Sonar is an aquatic herbicide developed specifically for the control of aquatic plants. It has been used for a number of years in other states, but was not approved for use in California until 1996. Sonar has no restrictions on use of the water after application and has been shown to be especially successful in controlling or even eradicating unwanted plants such as coontail and milfoil. These two noxious plants are the targets of the District's current weed harvesting programs and are the most annoying to boaters. The test proved very successful in giving three seasons of relief from weeds in the test area.
Plans are underway do to the positive test results.
The District is committed to continually investigating methods such as Sonar, which may be used in conjunction with the harvesting program, to provide the best and most cost effective plant control possible. The primary consideration when implementing new methods is to thoroughly evaluate the long range impacts which the introduction of a herbicide or chemical may have on the environment and the fishery.
