It is the purpose of this chapter to provide for the planning and construction of water storage, conservation, and regulation facilities and associated fish and wildlife and recreation features consistent with this declaration and to make provision for funds therefor on a continuing basis, and to provide for the operation and maintenance of such fish and wildlife and recreation features.

In enacting this chapter, however, it is not the intent of the Legislature to diminish any existing powers of the Department of Water Resources, the Department of Parks and Recreation, or the Department of Fish and Game, but rather to provide specifically for the preservation and enhancement of fish and wildlife resources and for a system of public recreation facilities at state water projects as part of a coordinated plan for multipurpose use of these projects.
