Pub. Resources Code, § 5094

It is hereby declared to be in the public interest for the state and local public agencies to participate with the federal government with respect to recreation and fish and wildlife enhancement facilities at federal water projects to the extent that such facilities are deemed necessary and desirable by the state or local public agency participating. The state may participate in any such project to the extent that it is of statewide importance and that local public agencies are unwilling or unable to do so and to the extent the Legislature appropriates funds necessary therefor. The state and local agencies may cooperate and jointly participate in a project where the interests of both will be advantageously served.
