OPINION
TOCI, Judge.
This is a petition for special action brought by defendant Salt River Valley Water Users’ Association (“SRP”) to review the trial court’s denial of a motion for summary judgment in a case in which a six-year-old child drowned in an SRP culvert. SRP claimed immunity from suit under the doctrine announced in Salladay v. Old Dominion Copper Mining Co., 12 Ariz. 124, 100 P. 441 (1909). The trial court denied SRP’s first motion for summary judgment, finding that disputed issues of fact existed concerning real parties in interests’ (“plaintiffs”) assertion that SRP was not protected from suit by the Salladay doctrine. The trial court refused to consider SRP’s second motion for summary judgment, concluding that the motion was a “horizontal appeal.” This court granted an interlocutory stay of the proceedings and accepted jurisdiction with this opinion to follow.
We first conclude that because SRP’s second motion for summary judgment was based on additional evidence discovered after the first motion for summary judgment, the second motion was not a “horizontal appeal.” Second, we conclude that because irrigation districts are immune from suit for attractive nuisance claims involving injury or death to trespassing children, SRP is entitled to the benefit of the Salladay doctrine. Finally, we conclude that plaintiffs did not establish a triable issue of fact that SRP acted with conscious disregard for the rights of the public so as to deprive SRP of immunity under Harris v. Buckeye Irrigation Co., 118 Ariz. 498, 578 P.2d 177 (1978). Consequently, we hold that SRP is entitled to immunity and that the trial court abused its discretion in not considering and granting SRP’s second motion for summary judgment.
FACTUAL AND PROCEDURAL BACKGROUND
The following facts are undisputed. On September 19, 1991, Kevin Paul Shoemaker, age six, was playing with two other boys in a SRP canal. He apparently lost his footing, floated downstream approximately fifty-eight feet, and drowned in a sixty-foot long enclosed culvert, approximately three and one-half feet in diameter, under Industrial Avenue in Chandler, Arizona. Kevin’s body was recovered from inside the culvert by a diver in scuba gear.
According to SRP written policy, a culvert of less than 100 feet in length did not require a trashrack or grate at the entrance unless “safety considerations justify a trashrackheadwall to prevent people from entering into the conduit.” Under this policy, SRP did not consider a trashrack necessary for safety reasons unless the culvert was obstructed by a water delivery structure that prevented an object from freely passing through the culvert. For example, the culvert downstream from Industrial Avenue— which is less than 100 feet in length—houses a turnout structure obstructing the exit from the culvert. Consequently, it has a trashrack installed at the inlet. Because the culvert under Industrial Avenue contained no such obstruction, under SRP’s policy a trashrack was not required at the entrance.
Plaintiffs’ expert established by affidavit that concrete canals, such as the lateral where the drowning occurred, are extremely hazardous. He concluded that the SRP canal where Kevin drowned did not meet the 1971 Bureau of Reclamation design standards. The side slopes of the canal were made of concrete and were very steep, which would prevent a person from climbing out of the canal. Furthermore, according to plaintiffs’ expert, the canal was devoid of safety measures recommended by the bureau. Specifically, the expert concluded that SRP could have “mitigated” the hazard to trespassing children either by replacing the open lateral with cast-in-place concrete pipe or by the installation of fencing to prevent access to the lateral. Alternatively, the affidavit of [73]*73plaintiffs’ expert established that SRP could have made the canal safer by installing ladders, cables and floats, nets, and safety screens and trash racks at the entrance to the culvert. Plaintiffs’ expert estimated the cost of a trash rack to be approximately $1000.
DISCUSSION
1. Is Special Action Relief Proper Where Qualified Tort Immunity is Asserted?
We begin with the proposition that denial of a motion for summary judgment is not appropriate for special action jurisdiction except in very unusual cases. Ft. Lowell-NSS Ltd. Partnership v. Kelly, 166 Ariz. 96, 99-100, 800 P.2d 962, 965-66 (1990); United States v. Superior Ct., 144 Ariz. 265, 269, 697 P.2d 658, 662 (1985). Nevertheless, there are exceptions to this general rule. Accordingly, we have accepted special action review in cases where defendant has claimed judicial immunity, Lavit v. Superior Ct., 173 Ariz. 96, 97, 839 P.2d 1141, 1142 (1992); Henke v. Superior Ct., 161 Ariz. 96, 98-99, 775 P.2d 1160, 1162-63 (App.1989), because if one is “erroneously forced to stand trial, he has lost the benefit of immunity, even if he is found not liable.” Henke, 161 Ariz. at 99, 775 P.2d at 1163. Consequently, a defendant who asserts an immunity has no adequate remedy at law by direct appeal after trial. Lavit, 173 Ariz. at 97, 839 P.2d at 1142.
Here, we can see little difference between the qualified common law tort immunity SRP claims under Salladay and the claim of judicial immunity in Lavit. Our supreme court has held for many years that common law tort immunity, whether absolute or qualified, protects not just from liability, but from suit. Henke, 161 Ariz. at 100, 775 P.2d at 1164. Thus, we conclude that special action relief is appropriate to enforce a claim of qualified tort immunity. See Bledsoe v. Goodfarb, 170 Ariz. 256, 266, 823 P.2d 1264, 1274 (1991) (the intent and viability of the Salladay doctrine and the interpretation of the recreational use statute have statewide significance).
2. Does A.R.S. Section 33-1551 Codify the Salladay Doctrine and Thus Preclude Special Action Relief?
Plaintiffs argue that because of the recent passage of Arizona’s amended recreational use statute, AR.S. section 33-1551, ch. 90, § 25, Ariz.Sess.Laws 265-66, this case is not appropriate for special action review. Thus, according to plaintiffs, the courts will no longer need to interpret Salladay because any case involving death or injuries resulting from SRP’s operations will be determined under section 33-1551. This argument has no merit.
Section 33-1551 is intended to promote the use of vast areas of unused land for recreational purposes. Bledsoe, 170 Ariz. at 259 n. 2, 823 P.2d at 1267 n. 2. It encourages owners of private and public lands to make their property accessible to the public by providing the owners with a broad immunity from suit for injuries. AR.S. § 33-1551(A). This broad immunity only applies, however, to suits by a “recreational user” or “educational user.” Id. A “recreational user” is defined as “a person to whom permission has been granted or implied ... to travel across or to enter upon premises.” A.R.S. § 33-1551(B)(3).
SRP policy, however, prohibits the recreational use of its canals and laterals. Because those who enter the canals and laterals do so without SRP’s permission, they are trespassers rather than recreational users and consequently are not covered by section 33-1551. Thus, the extent and viability of the Salladay doctrine continues to be a matter of judicial interpretation notwithstanding the amendment of section 33-1551.
3. Did the Trial Court Abuse its Discretion in Denying SRP’s Second Motion For Summary Judgment?
SRP’s first motion for summary judgment was filed in August of 1992. In response to that motion, plaintiffs argued that SRP was deprived of immunity because of its “public be damned” policy. According to plaintiffs’ response, as a result of SRP’s failure to clean the lateral and to install a trashrack grate on the entrance to the culvert, Kevin drowned [74]*74when “he became entangled in debris in the culvert.” The trial court denied the motion for summary judgment. It held that conflicting inferences could be drawn from the record about whether the Salladay doctrine applied and whether SRP was deprived of immunity because it had engaged in callous conduct toward the public.
Approximately four months from the denial of the first motion for summary judgment, after engaging in additional discovery and investigation, SRP filed a second motion for summary judgment. SRP supported the second motion with uncontroverted affidavits that no obstruction existed in the culvert that could have impeded Kevin’s passage through it and that Kevin did not, as plaintiffs claimed, become “entangled in debris.” SRP also produced uncontroverted evidence that by memo dated July 8, 1987, it adopted a policy requiring trashracks in short culverts “where safety considerations justify [them],” and that, after the drowning, it had rejected an internal suggestion to modify this safety policy. Nevertheless, the trial court denied the second motion, holding that it was an unauthorized “horizontal appeal” and not within the exception announced in Autonumerics, Inc. v. Bayer Indus., Inc., 144 Ariz. 181, 185, 696 P.2d 1330, 1334 (App.1984). We disagree.
After denial of a motion for summary judgment, a second motion is unauthorized when no new discovery has taken place. Chanay v. Chittenden, 115 Ariz. 32, 34, 563 P.2d 287, 289 (1977). In other words, if no new facts are produced, the parties are not allowed to relitigate a motion for summary judgment already decided. Here, however, additional discovery revealed uncontroverted evidence that refuted plaintiffs’ claim that SRP was deprived of immunity because it engaged in “public be damned” conduct. This case clearly falls within the Autonumerics exception to the prohibition against consideration of a second motion for summary judgment. Id., 144 Ariz. at 185, 696 P.2d at 1334.
The standard we apply in review of the trial court’s denial of a motion for summary judgment is whether the trial court abused its discretion. In exercising its discretion, the trial court is not authorized to misapply the law or a legal principle. City of Phoenix v. Geyler, 144 Ariz. 323, 328-29, 697 P.2d 1073, 1079-80 (1985). Here, the trial court misapplied the law announced in Autonumerics.
Furthermore, the facts produced in support of plaintiffs’ claim that SRP is not entitled to immunity because it engaged in “public be damned” conduct “have so little probative value ... that reasonable people could not agree with the conclusion advanced by [plaintiffs].” Orme School v. Reeves, 166 Ariz. 301, 309, 802 P.2d 1000, 1008 (1990). Thus, because the record shows that no real dispute exists as to any material fact regarding SRP’s immunity from suit, it was entitled to judgment as a matter of law. Ariz. R.Civ.P. 56(c); United Bank of Arizona v. Allyn, 167 Ariz. 191,196, 805 P.2d 1012, 1017 (App.1991). Under these circumstances, the trial court’s failure to consider and grant SRP’s motion for summary judgment was an abuse of discretion.
4. Is the Salladay Doctrine Still Viable in Arizona?
We reject plaintiffs’ argument that the Salladay immunity is a relic of the past and that changing conditions dictate that it be abolished. Even if we were so inclined to hold, we are bound by the prior decisions of our supreme court. We hold that the Salladay doctrine remains a viable defense to suits against an irrigation company “based on the theory that the operation of an unfenced canal and its equipment is per se an act of negligence.” Bledsoe, 170 Ariz. at 266, 823 P.2d at 1274.
In Salladay, the plaintiff alleged that a three-year-old child fell into an uncovered mining flume that discharged water over a fifteen-foot fall. The child was swept along by the rushing water and carried over the fall to her death. The issue was whether the flume, with its rushing water, was an attractive nuisance for which defendant was required to maintain “a proper inclosure, covering, or other safeguard.” 12 Ariz. at 126-28, 100 P. at 441-42. The Arizona Supreme Court affirmed the dismissal of the plaintiffs [75]*75complaint by the trial court, holding that as a matter of law and public policy, the attractive nuisance doctrine should not be applied to the maintenance of a flume to transport water. Id. at 129-31, 100 P. at 442-43.
Our supreme court has recently noted, in a case involving a bicyclist injured by a cable gate stretched across an SRP canal access road, that the same considerations applied in Salladay in 1906 apply today in deciding when an irrigation company is entitled to tort immunity. Bledsoe, 170 Ariz. at 263, 823 P.2d at 1271. These considerations are that (1) it is impossible to render canals harmless, (2) such conduits “ ‘are indispensable for the maintenance of life and prosperity,’ ” and (3) because the danger of open canals is obvious, “ ‘defendant [is] entitled to assume that plaintiffs natural guardians [will] protect him from any dangers attached thereto.’ ” Id. at 263-64, 823 P.2d at 2171-72. In Bledsoe, the court concluded that the dangers of canal roads “are simply not comparable to the operator’s inability to protect children from the inherent, unavoidable dangers of open canals.” Id. at 265, 823 P.2d at 1273.
The Bledsoe court also recognized that “the continued delivery of irrigation water to our arid land” is still an important policy rationale behind the Salladay doctrine. Id. 170 Ariz. at 263, 266, 823 P.2d at 1271, 1274. Here, plaintiffs argue otherwise, asserting that SRP is asking for the continuance of “84 year old policies that make no sense today.” According to plaintiffs, and we agree, in Dombrowski v. Maricopa County Mun. Water Conservation Dist., 108 Ariz. 275, 276-77, 496 P.2d 136, 137-38 (1972) and Hersey v. Salt River Valley Water Users’ Ass’n, 10 Ariz.App. 321, 327, 458 P.2d 525, 531 (1969), our appellate courts “recognized that [the] urbanization of Arizona ... may lead to the need to abandon Salladay.” Nevertheless, although plaintiffs may question the wisdom of the Salladay doctrine, we are, in the language of this court in Hersey, “bound by the prior decisions of the Arizona Supreme Court until changed by that court.” Hersey, 10 Ariz.App. at 327, 458 P.2d at 531 (citing McKay v. Industrial Comm’n, 103 Ariz. 191, 438 P.2d 757 (1968)).
Consequently, at least with regard to trespassing children who drown in irrigation canals, as a matter of public policy, the Salladay doctrine is as viable today as it was in 1906. See Bledsoe, 170 Ariz. at 266, 823 P.2d at 1271; Harris, 118 Ariz. at 502, 578 P.2d at 181 (“[Salladay ] is sound public policy today as far as the use of canals ... [is] concerned.”). Nor are we convinced that Arizona is out of step with other states. Although plaintiffs assail the doctrine by pointing to the Restatement (Second) of Torts § 339 (1965) (“Restatement”)1 as the “modem formulation of landowner liability,” we are not convinced. Before section 339 can be applied the court must find “(d) the utility to the possessor of maintaining the condition and the burden of eliminating the danger are slight as compared with the risk____” Restatement § 339(d).
Here, the uncontradieted evidence in the record indicates that SRP has over 1000 miles of canals, laterals, and culverts in the Phoenix area. These canals are essential for the delivery of water for both agricultural and urban use in central Arizona. Moreover, the canal system is an obvious, inherently dangerous condition that cannot be feasibly rendered harmless. Consequently, because the utility of maintaining the canal system and the burden of eliminating the danger are [76]*76great, no basis exists to apply section 339 of the Restatement. Thus, even if plaintiffs are correct that section 339 should apply to determine whether SRP has attractive nuisance liability, it avails them nothing under these circumstances. Accord Hanners v. City of Ashland, 331 S.W.2d 729, 730 (Ky.1959) (reservoir cannot be considered an attractive nuisance in light of costs of safeguards); Frensley v. Gravity Drainage Dist. No. 5, 180 So.2d 743, 744-45 (La.App.1965) (drainage canal is not an attractive nuisance under Restatement § 339(d)); Mellas v. Lowdermilk, 58 N.M. 363, 271 P.2d 399, 403 (1954) (pond is not an attractive nuisance in light of its usefulness and the impossibility of rendering it harmless); Loveland v. Orem City Corp., 746 P.2d 763, 772-73 (Utah 1987) (canal is not an attractive nuisance in light of its usefulness and the cost of fencing).
The dissent argues that we “improperly considered] the cost of eliminating the danger in all of the Salt River Project’s more than 1000 miles of canals,” and that “SRP has not proved ... that the risk to Kevin Shoemaker and other children is outweighed by the $1,000 expense of installing a trash-grate on a culvert of less than 100 feet.” The conclusion we reach in this opinion, however, is that the attractive nuisance doctrine embodied in section 339 of the Restatement does not apply to SRP because of Salladay and its progeny. We discuss the risk-benefit issue in the preceding paragraph only in the context of considering whether, if plaintiffs are correct in asserting the application of section 339, that section imposes liability on SRP for the death of Kevin Shoemaker. We conclude above that even if we accept plaintiffs’ argument that section 339 is applicable, the risk-benefit analysis in section 339(d) would preclude plaintiffs from recovering from SRP under a section 339 theory. See Bledsoe, 170 Ariz. at 263-64, 823 P.2d at 1271-72 (“ ‘such conduits [are] practically impossible to render harmless’ ... [and] ‘are indispensable for the maintenance of life and prosperity”’). Because section 339 of the Restatement does not apply, however, SRP does not have to prove that the benefit of maintaining its canal system outweighs the risk to trespassing children.
5. Does Salladay Exempt SRP From Liability For Ordinary Negligence?
Plaintiffs argued in the trial court that factual questions about the amount of debris in the culvert and SRP’s negligence in failing to install trashraeks deprive SRP of immunity. We reject this argument. Because the Salladay doctrine is applicable, SRP’s negligence in failing to install trash-racks or in allowing the accumulation of debris in the culvert is not actionable.
The Bledsoe court observed that since Salladay, “our courts have expanded the doctrine to protect canal operators from attractive nuisance claims involving the maintenance of essential components of a canal system.” 170 Ariz. at 264, 823 P.2d at 1272 (citations omitted). That court also remarked that in each of the cases in which the courts have protected the canal operator from liability “the child was injured by the canal itself or some device closely connected with the canal.” Id.
Consequently, the application of the Salladay doctrine does not depend on the location in the canal system where the death or injury occurred or the instrumentality that ultimately caused it. In other words, the fact that the death or injury occurred in a subterranean culvert, which may even be more dangerous than the canal itself for one reason or another, is not determinative of whether the canal operator is entitled to immunity. The immunity shields SRP from the claims of all those who are injured by the canal itself or by equipment used as an essential component of the canal system. See Salladay, 12 Ariz. at 129, 100 P. at 442. (“There is no distinction that properly can be drawn for liability for injuries received by a child from any of such various means of diversion or use of water.”).
Other decisions of our supreme court and this court support the latter conclusion. For example, in Dombrowski, the supreme court held that a whirlpool created by a waterfall in the canal is covered by the Salladay doctrine. 108 Ariz. at 277, 496 P.2d at 138. And in Lee v. Salt River Valley Water Users’ Association, 73 Ariz. 122, 126, 238 P.2d 945, 948 (1951), the supreme court found that [77]*77weirs, or water troughs, at a canal pumping station were so similar to the canal itself as to be covered by the doctrine. Id.,Id., 73 Ariz. at 126, 238 P.2d. at 948. Later, in Elkins v. Roosevelt Water Conservation Dist., 22 Ariz. App. 130, 131, 524 P.2d 964, 965 (1974), this court held that because a conservation district’s electrical transformer adjacent to an open trough was an essential component of the system for discharging water, it was covered by the Salladay doctrine.
Finally, in Hersey, the plaintiff, in an effort to circumvent Salladay, made essentially the same argument as plaintiffs make in this case. There, as a result of an automobile accident on a street adjacent to the canal, a child was thrown into the canal. She drowned in a culvert after passing through a defective trashgrate installed at the entrance to the culvert. Hersey, 10 Ariz.App. at 322-23, 458 P.2d at 526-27. The plaintiff argued that Salladay was not applicable because plaintiffs’ theory of recovery was not based upon SRP’s negligence in maintaining the open canal, but rather was based upon SRP’s negligence in failing to install a trashrack at the entrance to the culvert where the plaintiff drowned. Id. at 327, 458 P.2d at 531. This court held that such distinction was not meaningful and “[t]he reasoning of Salladay would apply equally to the diversion facilities from the canal to the underground culvert.” Id.
We now turn to plaintiffs’ assertion that an exception to the the Salladay doctrine exists when the danger was temporary or unexpected, or not entirely open to observation. According to plaintiffs, Salladay does not “eliminate the obligation of canal operators to exercise reasonable care where the danger is hidden.” Thus, plaintiffs argue, there are two disputed fact issues precluding summary judgment: first, whether SRP negligently designed and maintained the canal without “trashracks ... to render it free of debris,” and second, whether SRP knew of debris clogging the culvert and negligently failed to remove it. According to plaintiffs theory, SRP’s negligent failure to install trashracks and to remove debris from the lateral upstream from the Industrial Avenue culvert created an “impassable wall of debris” that prevented Kevin’s body from passing through the culvert. Plaintiffs assert that because the “debris filled culvert” was an additional danger that was not open and obvious and was unexpected to the public, SRP is deprived of the Salladay immunity. We reject this argument for the following reasons.
First, we observe that even if SRP is not entitled to the benefit of the Salladay doctrine, plaintiffs’ contentions, unsupported by any citation to the record, would not be sufficient to create a disputed issue of fact regarding SRP’s negligence. Brown Wholesale Elec. Co. v. Safeco Ins. Co. of America, 135 Ariz. 154, 158, 659 P.2d 1299, 1303 (App. 1982). Furthermore, after reviewing the record, we find that plaintiffs’ counsel has misrepresented the record concerning the existence of purported debris in the canal. No competent evidence exists in this record to support plaintiffs’ contention that SRP allowed debris to accumulate in the canal or culvert or that an “impassable wall of debris” prevented Kevin’s body from passing through the culvert.
Instead, the undisputed evidence indicates that the culvert was free of debris when the drowning occurred. Although plaintiffs argue that SRP was aware of debris in the canal and “took no action to clean” it, the affidavit of SRP employee James Duncan refutes this argument. Duncan’s affidavit establishes that about one month before the accident he confirmed the removal of the dirt about which plaintiffs complain. Furthermore, the affidavits of the divers who entered the Industrial Avenue culvert establish that “the culvert was not impeded or restricted by any debris” and they were able to move freely through it. Photos taken after the culvert was emptied of water confirm this testimony; they show only a few small rocks and other debris littering the floor of the three and one-half foot culvert. Finally, the affidavit of Richard Weyenberg, the diver who retrieved Kevin’s body from the culvert, states that “it did not feel to me that the child was caught up on anything in the culvert.”
Second, the Salladay decision involved the resolution of two separate issues, neither of [78]*78which creates an exception to the immunity of canal operators. The first issue in Salladay—the issue in which the Salladay immunity has its genesis—dealt with the question of whether the attractive nuisance doctrine should be extended to a flume owned and operated by a mining company. Salladay, 12 Ariz. at 129, 100 P. at 442. For public policy reasons, the court refused to extend the holding in the “turntable case” of Sioux City & Pacific R.R. Co. v. Stout, 84 U.S. 657, 21 L.Ed. 745 (1874), to the facts of the Salladay case, thus giving birth to the so-called “Salladay doctrine” of tort immunity of canal operators. Salladay, 12 Ariz. at 129-30, 100 P. at 440.
Having refused to extend the holding of Stout, the Salladay court then turned to the question of whether Stout was controlling as precedent. Our supreme court concluded that because Stout represented an exception to the rule of nonliability of landowners for injuries to trespassing children, Stout was controlling only in the limited situation where the danger was hidden or unexpected. Id. at 130, 100 P. at 442-43. In other words, the Salladay court limited the application of the attractive nuisance doctrine announced in Stout to dangers that are “temporary or unexpected, or not entirely open to observation.” Id. The court did not, as plaintiffs contend, create an exception to the immunity of a canal operator for dangers that are “temporary or unexpected, or not entirely open to observation.” Id.
Third, one of the elements of an attractive nuisance is a condition “the possessor knows or has reason to know and which he realizes or should realize will involve an unreasonable risk of death or serious bodily harm to such children.” Restatement § 339(b); MacNeil v. Perkins, 84 Ariz. 74, 81, 324 P.2d 211, 215-16 (1958). Thus, one cannot logically argue that the Salladay doctrine immunizes SRP from liability for harm caused by children attracted to its highly dangerous canal system and in the same breath argue that SRP is required to exercise reasonable care for the safety of these same children. The two concepts are mutually exclusive. Under the Salladay doctrine, SRP is immunized from liability for maintaining an unfenced canal and its equipment— conditions which a reasonable, prudent person would recognize as involving an unreasonable risk of harm to trespassing children. If, as plaintiffs argue, SRP must exercise reasonable care to protect children who may be attracted to its canal system, SRP could never avail itself of the protection afforded by Salladay.
Finally, plaintiffs’ argument is refuted by Hersey. There, the specific act of negligence alleged against SRP was the failure “‘to properly install and maintain a grate’ ” at the entrance to a culvert. Hersey, 10 Ariz.App. at 326-27, 458 P.2d at 530-31. The Hersey court found both the existence of a duty to the plaintiff and foreseeability, but concluded that because of the Salladay doctrine, SRP’s conduct in failing to install and maintain the grate was not actionable negligence. Id. at 327, 458 P.2d at 531. Here, the negligence alleged against SRP—the failure to “conform with usual or customary precautions in design, construction and maintenance of the canal, such as the installation of trashracks ... placement of exit steps in the lateral and cleaning ... the culvert”—is similar to the negligence alleged against SRP in Hersey.
Consequently, because of the Salladay doctrine, SRP’s claimed omissions do not constitute actionable negligence. For this reason, we do not consider the claim by plaintiffs’ expert that SRP negligently violated the Bureau of Reclamation Standards by failing to install trashracks, by failing to fence the canal and by failing to install cast-in-place concrete pipe as a substitute for the open lateral.
6. Did SRP Engage in the “Public Be Damned” Conduct Condemned by Harris v. Buckeye Irrigation Company, 118 Ariz. 498, 578 P.2d 177 (1978)?
Plaintiffs argue that an issue of fact existed as to whether this case falls within the Harris, “public be damned” exception to Salladay. We disagree. First, we do not read Harris as broadly as do plaintiffs. Second, the facts of this case are distinguishable from the facts of the Harris case and do not fall within the rule announced in Harris. Consequently, we conclude that on this ree[79]*79ord plaintiffs have not established that SRP’s conduct deprived it of immunity under the Harris case.
A. Does Harris Apply To These Facts?
Harris involved a makeshift footbridge constructed by Buckeye Irrigation Company (“Buckeye”). The bridge consisted of two warped and uneven boards nailed together, totalling 24-inches wide, improperly anchored and without handrails. Although the bridge was constructed by Buckeye employees and used for employee access over the canal to an irrigation checkpoint, it was also frequently used by the public as the most direct method of access from the residential area north of the canal to the high school, baseball field, and swimming pool on the south side of the canal. Several hundred children used the bridge daily to travel back and forth from their homes to the high school and ball fields. One of these children, Marlon Harris, drowned when he fell from his bicycle while attempting to cross the bridge to go to the ball field south of the canal. Harris, 118 Ariz. at 499-501, 578 P.2d at 178-80.
Although Buckeye knew about the public use of the bridge and was aware of prior incidents involving a drowning and a near drowning resulting from a fall from the bridge, the company exerted no effort to make the bridge safe. It erected no signs warning of the danger and took no steps to discourage public use. Furthermore, Buckeye rejected an offer by school officials to construct a safer bridge over the canal at no cost to Buckeye. Finally, and perhaps most significant, Buckeye’s manager testified at his deposition that although he knew the bridge was dangerous, he had no obligation to make the bridge safe because the children were “trespassers.” Id. at 499-502, 578 P.2d at 178-81.
The Arizona Supreme Court held that such conduct resulted in the loss of immunity. It said, “[ujnfortunately, this immunity sometimes leads to the callous ‘public be damned’ policy exemplified by the testimony of the manager ... in the instant case.” Id. at 502, 578 P.2d at 181. Nevertheless, the reason for the court’s ruling was clearly prophylactic: to prevent irrigation companies “from using a grant of immunity as an excuse not to exercise reasonable care to protect the ... public from a negligently constructed ... bridge they knew was being used by the public.” Id. (emphasis added).
Later, after the Harris case was tried in the superior court and appealed, this court upheld an award of punitive damages against Buckeye for its wilful and wanton conduct. Harris v. Buckeye Irrigation Co., 131 Ariz. 540, 545, 642 P.2d 885, 890 (App. 1982) (“Harris II ”). In Harris II, we also observed that no Arizona case supported an immunity for wilful and wanton conduct based on the Salladay doctrine. Id. Thus, our holding in Harris II makes it clear that where an irrigation company engages in conduct that gives rise to an award of punitive damages, it is not entitled to immunity. On the other hand, contrary to SRP’s argument, the Harris eases do not stand for the proposition that an irrigation company can be deprived of Salladay immunity only where its conduct rises to the level of conduct justifying an award of punitive damages.
Plaintiffs argue that Harris does away with immunity “where the accident could have been avoided had the canal operator exercised reasonable care and such care was not exercised because of the grant of immunity.” We disagree. The immunity provided by Salladay would be meaningless if an irrigation company could be deprived of the immunity simply by relying upon it. Neither does Harris require us to reach this conclusion. The crux of Harris is that an irrigation company cannot acquiesce in public use of a dangerous bridge it has constructed and then, relying upon its immunity, refuse to make the bridge safe for such use.
This case is different from Harris. Here, no evidence exists that the public used the lateral for swimming or that any other incidents of this nature occurred at or near the culvert under Industrial Avenue. Neither is there any evidence that SRP acquiesced in public use of the lateral. On the contrary, SRP expressly prohibits swimming in its canals and laterals.
[80]*80B. Does the SRP Memorandum Demonstrate Callous Conduct?
Plaintiffs next point to an SRP memo dated October 24, 1991, to demonstrate SRP’s “public be damned” conduct. In that memo, Harold Biever, an SRP employee, noted that the company’s policy was to install trash-racks on culverts less than 100 feet in length “ “where safety considerations justify [it].’ ” The memo notes that this is an expensive policy and recommends that instead of installing trashracks on such culverts, SRP should “hang its hat on the legal opinion of SRP’s Law Department.”
Athough plaintiffs argue that the memo demonstrates SRP’s “public be damned attitude,” we are unable to find any evidence in the memo that supports this argument. The opinion of SRP’s law department referred to in Harold Biever’s October 24, 1991 memo, was rendered on April 27, 1987. Athough the April 27, 1987 legal opinion suggested that SRP should not, because of its immunity, install trashracks “solely for the purposes of protecting the public,” that recommendation was not followed by SRP. When SRP adopted its design criteria for trashracks on July 8, 1987, it provided “[a] trashrack-headwall may be required for shorter lengths of conduit where safety considerations justify [it] to prevent people from entering into the conduit.” (Emphasis added.) Furthermore, Biever’s recommendation, made several months after Kevin drowned, was never adopted by SRP. Thus, the July 8, 1987 policy on trashracks, which expressly acknowledged safety concerns, was in effect both before and after the drowning. Consequently, nothing in the Biever memo demonstrates that SRP engaged in conduct which, under Harris, would deprive SRP of immunity-
CONCLUSION
We conclude that the Salladay doctrine is still viable to immunize canal operators from liability for trespassing children who drown in an irrigation canal. Athough a canal operator who engages in “public be damned” conduct may be deprived of that immunity, we conclude that plaintiffs have not demonstrated that a triable issue of fact exists on this point. We hold that SRP is entitled to immunity and that the trial court abused its discretion in denying SRP’s motion for summary judgment.
