Public Resources Code section 5093.542
(a)
The continued management of river resources in their existing natural condition represents the best way to protect the unique fishery of the McCloud River. The Legislature further finds and declares that maintaining the McCloud River in its free-flowing condition to protect its fishery is the highest and most beneficial use of the waters of the McCloud River within the segments designated in subdivision (b), and is a reasonable use of water within the meaning of Section 2 of Article X of the California Constitution.(b)
A dam, reservoir, diversion, or other water impoundment facility shall not be constructed on the McCloud River from Algoma to the confluence with Huckleberry Creek, and 0.25 mile downstream from the McCloud Dam to the McCloud River Bridge and such a facility shall not be constructed on Yét Atwam Creek from the confluence with Cabin Creek to the confluence with the McCloud River.(c)
Except for participation by the Department of Water Resources in studies involving the technical and economic feasibility of enlargement of Shasta Dam, a department or agency of the state shall not assist or cooperate with, whether by loan, grant, license, or otherwise, any agency of the federal, state, or local government in the planning or construction of any dam, reservoir, diversion, or other water impoundment facility that could have an adverse effect on the free-flowing condition of the McCloud River, or on its wild trout fishery.(d)
A state agency exercising powers under any other law with respect to the protection and restoration of fishery resources shall continue to exercise those powers in a manner to protect and enhance the fishery of those segments designated in subdivision (b). In carrying out this subdivision, the exercise of powers shall be consistent with Section 5093.58.(e)
This section does not prejudice, alter, affect in any way, or interfere with the construction, maintenance, repair, or operation by the Pacific Gas and Electric Company of the existing McCloud-Pit development (FERC 2106) under its license, or prevent Pacific Gas and Electric from constructing a hydroelectric generating facility by retrofitting the existing McCloud Dam if the operation of the facility does not alter the existing flow regime below the dam.
