California Harbors And Navigation Code Section 64
(a) The Legislature hereby finds and declares that the growth
of water hyacinth and Egeria densa 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 and Egeria densa 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 and Egeria densa 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 and Egeria densa
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 and
Egeria densa 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
(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.
