California Code, Water Code - WAT § 141

(a) The department may establish a program to authorize private entities to lease space above or adjacent to appropriate conveyance facilities of the State Water Project for the purpose of installing solar photovoltaic panels and systems for generating electricity from those panels and transferring electricity through the related systems. Upon request, the department shall evaluate proposals for installing solar photovoltaic panels and related systems for the generation and transfer of electricity. A proposal submitted to the department for evaluation shall include, but need not be limited to, an engineering study of the proposed solar photovoltaic panels and related systems and an evaluation of the effect the solar photovoltaic panels and related systems may have on water supply, water quality, worker safety, and liability considerations. The costs of the engineering study and the department's evaluation shall be paid by the person or entity making the request.

(b) After approval of a proposal as described in subdivision (a), the department may negotiate any level of compensation for an agreement for the installation of solar photovoltaic panels and related systems that is equal to, or greater than, the cost to the department of meeting its obligations under the agreement. These costs shall include, but are not limited to, the costs of operating and maintaining State Water Project facilities and lease administration that are directly related to the lease and use of the conveyance facilities.
