California Code, Harbors and Navigation Code - HNC § 64

(a) The Legislature hereby finds and declares that the growth of water hyacinth (Eichhornia crassipes), Brazilian elodea (Egeria densa), and South American spongeplant (Limnobium laevigatum) in the Sacramento-San Joaquin Delta, its tributaries, and the Suisun Marsh has occurred at an unprecedented level and that the resulting accumulations of water hyacinth (Eichhornia crassipes), Brazilian elodea (Egeria densa), and South American spongeplant (Limnobium laevigatum) obstruct navigation, impair other recreational uses of waterways, have the potential for damaging manmade facilities, and may threaten the health and stability of fisheries and other ecosystems within the delta and marsh. Accordingly, it is necessary that the state, in cooperation with agencies of the United States, undertake an aggressive program for the effective control of water hyacinth (Eichhornia crassipes), Brazilian elodea (Egeria densa), and South American spongeplant (Limnobium laevigatum) in the delta, its tributaries, and the marsh.

(b) The department is designated as the lead agency of the state for the purpose of cooperating with agencies of the United States and other public agencies in controlling water hyacinth (Eichhornia crassipes), Brazilian elodea (Egeria densa), and South American spongeplant (Limnobium laevigatum) in the delta, its tributaries, and the marsh.

(c) The department, other state agencies, cities, counties, and districts are hereby authorized to cooperate with one another and with agencies of the United States in controlling water hyacinth (Eichhornia crassipes), Brazilian elodea (Egeria densa), and South American spongeplant (Limnobium laevigatum) in the delta, its tributaries, and the marsh and may furnish money, services, equipment, and other property to that end.

(d) Up to five thousand dollars ($5,000) per year of the funds available for expenditure by the Department of Fish and Game to implement this section shall be paid from the Harbors and Watercraft Revolving Fund.

(e) Whenever any control program is proposed to take place in Rock Slough, the department and the Contra Costa Water District shall develop a memorandum of understanding establishing the parameters of the control program. This subdivision does not apply to any control program proposed for Sand Mound Slough.
