Cal. Wat. Code § 12898
The Sacramento Canals Unit of the Central Valley Project is approved for state participation to the extent that funds are hereafter appropriated therefor.
The department may enter into a contract with the Federal Government on behalf of the State under which the State agrees to pay to the Federal Government, each year that the net revenue derived from the operation of the Sacramento Canals Unit is less than the amount necessary to pay the appropriate share of the reimbursable construction cost of the unit allocated for repayment in that year, an amount equal to the difference between the revenues received and the amount so allocated for repayment. The contract shall condition any payment upon an appropriation being made therefor.
