SAN LUIS OBISPO COASTKEEPER, ET AL V. SANTA MARIA VALLEY WATER CONSE, ET AL, No. 21-55479 (9th Cir. 2022)
Annotate this Case
The Ninth Circuit reversed the district court’s summary judgment in favor of the Bureau of Reclamation and the Santa Maria Water District (collectively, the “Agencies”) in an action brought by San Luis Obispo Coastkeeper and Los Padres ForestWatch (“Plaintiffs”), claiming that the Agencies’ operation of Twitchell Dam interfered with Southern California Steelhead’s reproductive migration, which constituted an unlawful take in violation of the Endangered Species Act (“ESA”).
The panel held that under PL 774, the Agencies had discretion to release water from Twitchell Dam to avoid take of endangered Southern California Steelhead. The panel held that PL 774 expressly authorized Twitchell Dam to be operated for “other purposes” beyond the enumerated purposes. As a secondary priority, PL 774 also required the Agencies operate the dam substantially in accordance with the Secretary’s Report. The statutory requirement of substantial compliance—rather than strict compliance—with the Secretary’s Report explicitly grants discretion to the Agencies to adjust the dam’s flow rate.
The panel held that this interpretation is buttressed by the principles of statutory construction. Because PL 774 and the ESA can easily be read to work in harmony, it was the panel’s duty to do so. Here, there is no clear Congressional intent to preclude the dam from being operated to avoid take of Southern California Steelhead. There is no implied conflict between PL 774 and the ESA. Twitchell Dam can readily be operated to provide modest releases at certain times of the year and during certain water years, while still satisfying the dam’s primary purpose of conserving water for consumptive purposes.
