Invasive Aquatic Species in the Delta
The Delta Protection Commission supports the control of invasive aquatic species, primarily Egeria densa (Brazilian Elodea) and water hyacinth, which negatively impact Delta recreational navigation, tourism and water supply. The California State Parks Division of Boating and Waterways (DBW) is the State lead agency in the effort to control Egeria densa and water hyacinth in the Sacramento-San Joaquin Delta, its tributaries, and the Suisun Marsh.
Delta residents and businesses are encouraged to learn more about DBW’s Aquatic Weed Control Program and sign up for Weekly Control Treatment Notifications, as well as learn how to prevent the spread of invasive species.
In 2014, Commissioners Mary Nejedly Piepho (Supervisor, Contra Costa County) and Larry Ruhstaller (Supervisor, San Joaquin County) prepared and submitted a white paper on invasive aquatic weeds to the Delta Plan Interagency Implementation Committee. Read it here.
