They have been doing that for years here at Clearlake and the Delta. I contacted Ca fish and Wildlife about it at least 10 years ago. Their answer was it doesnt effect enough of the lake at once to make a difference.Why the need to spray in late fall make no sense here because all the weeds die off in winter anyways.Most of all the water companies around the lake draw water off the lake and really makes me wonder what we are showering ourselves with. The outflow of Clearlake goes right into the rice fields in the valley and also wonder how much at risk chemicals also go into the rice fields. Think about that with your next bowl of rice!!
