FIRST APPELLATE DISTRICT

DIVISION THREE

TIMOTHY JAMES DUMMER, Plaintiff and Appellant, A172588 v. CITY AND COUNTY OF SAN (Alameda County FRANCISCO et al., Super. Ct. No. 23CV036826) Defendants and Respondents.

The question presented is whether plaintiff Tim Dummer is entitled to a writ of mandate compelling the public entity defendants to obtain an amended water supply permit and open the Calaveras Reservoir— immediately and in its natural state—to public fishing. Dummer contends a writ is appropriate because defendants have a ministerial duty to act under provisions of the Fish and Game Code, the Health and Safety Code, and various constitutional provisions, and have failed to do so. Our review of the relevant laws leads us to conclude that Dummer has not established a right to mandamus relief. Specifically, he has not demonstrated defendants’ failure to perform a ministerial duty. We will affirm the judgment. FACTUAL AND PROCEDURAL BACKGROUND Plaintiff Dummer is a licensed California fisherman who has long sought access to fish at the Calaveras Reservoir.

1 Defendants are the City and County of San Francisco and the San Francisco Public Utilities Commission (“SFPUC”). 1 The City is the owner of the Calaveras Reservoir, which is located in the counties of Alameda and Santa Clara and contains fish species including resident rainbow and anadromous steelhead trout. The reservoir provides drinking water to 2.7 million residents across several Bay Area counties and is part of a watershed governed by the Alameda Watershed Management Plan. SFPUC adopted the management plan in April 2001 after conducting an environmental review pursuant to the California Environmental Quality Act (Pub. Res. Code, § 21000 et seq.; “CEQA”). The plan’s purpose is “to provide for improved management of the watersheds to meet the primary goal of water quality protection as well as the secondary goals of watershed management.” The plan currently prohibits public access and fishing at the Calaveras Reservoir. A. Dummer I In 2019, Dummer filed a petition for writ of mandate seeking to compel the City to immediately determine that public fishing would not affect the purity and safety of the water at the Calaveras Reservoir and to obtain a valid water supply permit setting forth the terms and conditions upon which public fishing at the reservoir may be conducted (“Dummer I”). Dummer raised claims under the California Constitution, the Fish and Game Code, and the Health and Safety Code. At the hearing on the matter, the trial court recognized, first, the public right to fish in a reservoir is a qualified right, and second, the issue is whether public fishing could occur in the Calaveras Reservoir without

2 affecting the water’s purity. Viewing the matter as not necessarily presenting “a simple yes-or-no proposition,” the court stated the City would need to consider a fishing program specific to the Calaveras Reservoir with potential time, place, and manner restrictions, as well as what facilities would be needed. The court elaborated as follows. If the City determines that public fishing will not prevent the delivery of pure drinking water with an appropriate fishing program in place, the City would then be “obligated” under Health and Safety Code section 117045 to propose such a program with an appropriate environmental evaluation under CEQA and to include whatever program terms and conditions the City deems necessary in its application to the State Water Resources and Control Department (“SWRCB”) for an amended water supply permit. At that point, SWRCB will consider whether to issue a permit with the City’s proposed terms and conditions. 2 The court ultimately ruled the City had a present ministerial duty to determine “whether fishing in the reservoir is something that can be accomplished without affecting the purity of the water” provided to users, but it emphasized the City had no other ministerial duties to perform at that point. Consistent with its oral pronouncements, the trial court issued an order granting Dummer’s petition with a finding that the City had “a present ministerial duty to make a determination as to whether fishing in the Calaveras Reservoir can be accomplished without ‘affect[ing] the purity and safety for drinking and domestic purposes of the water collected in the reservoir’ under Health & Safety Code § 117045.” The court ordered the City

2 For purposes of this appeal, we accept the parties’ mutual understanding that SWRCB oversees the water supply permit process set forth in the Health and Safety Code statutes and regulations discussed herein.

3 “to commence the evaluation required to make such determination immediately,” taking into consideration “all of the variables described in Health & Safety Code §§ 117040, 117045, 117050, 117055, 117060 and 117065.” The City thereafter complied with the trial court’s order. In Resolution 22-0135, the City determined: “[S]ubject to the results of any CEQA review and the analysis of the State’s Office of Drinking Water [a division of SWRCB], . . . shoreline fishing by the public can occur under terms to be set by [SFPUC’s] General Manager without affecting the purity and safety for drinking and domestic purposes of the water collected in Calaveras Reservoir.” The resolution further reflected the City’s authorization of its General Manager “to develop the terms and conditions of a fishing program, obtain the City Planning Department’s review of that program under CEQA; request an amendment to the drinking water permit from the State’s Office of Drinking Water; and present to [the City] proposed amendments to the 2000 Alameda Watershed Management Plan to allow limited public shoreline fishing at Calaveras Reservoir.” B. The Instant Lawsuit After adopting Resolution 22-0135, the City started planning for a fishing program at the reservoir. The City determined that instituting a fishing program would require improvements designed to ensure the safety of the public and staff, protect the watershed and drinking water quality, and safeguard SFPUC infrastructure. Proposed improvements included widening the existing access road to create safe travel conditions, expanding the existing paved landing area to accommodate public parking and restrooms, adding security fencing to protect existing infrastructure and prevent trespass, and installing signage to direct visitors to the public access areas.

4 Upon learning the Calaveras Reservoir would not immediately open for fishing while the City considered the necessity and parameters of a fishing program, Dummer filed a petition for writ of mandamus and complaint for declaratory and injunctive relief, and damages. Dummer sought to compel the City to perform the following acts, which he contends are mandatory and ministerial: (1) obtain the requisite water supply permit from SWRCB pursuant to Health and Safety Code section 117045; and (2) provide public access for fishing during open season pursuant to Fish and Game Code section 5943 and California Constitution, article I, section 25 and article X, sections 2 and 4. He also sought the City’s prompt performance of additional “incidental” actions such as “consulting with agencies, developing a fishing program (where required by law), completing environmental review or negative declaration, amending an existing drinking water permit, and providing correct signage regarding public access and fishing rules versus trespass.” The trial court denied Dummer’s petition, concluding he failed to identify any breach by the City of a ministerial duty.
