California Code, Water Code - WAT § 12053

(a) As a provision of any contract entered into pursuant to Section 12052, and for the purpose of securing its performance thereunder, the department may assign rights which have accrued or which will accrue to the department from the execution of contracts entered into pursuant to the provisions of subdivision (b) of Section 12054.

(b) Such rights may be effectively assigned notwithstanding the fact that contracts creating such rights have not, at the time of the assignment of rights to accrue thereunder, been executed, the provisions of Section 1045 of the Civil Code or of any other provision of law to the contrary notwithstanding.  The department may require, as a condition precedent to its duty to perform any obligation incurred by virtue of its entry into any contract pursuant to Section 12052, the subsequent execution of all contracts to be entered into by the department pursuant to subdivision (b) of Section 12054 which are to create the rights assigned.

(c) The department may give such assurances, in the form of covenants in contracts to which it is a party pursuant to the provisions of Section 12052, as may be required by the terms of any interstate compact which effectively allocates water supplies from the Washoe Project or from any division or unit thereof, or by the federal government, including any agency thereof, as operating agency of the Washoe Project or of any division or unit thereof, which assurances are in the judgment of the department necessary and proper to the execution of the intent expressed by this part.
