I have an oxbow off of a bayou in Louiaiana that floods and has some current in it every year during the spring. The lake is only 150 feet to 200 feet wide but 3 miles long. We have it dammed with a spillway at one end. The lake has a fairly large watershed and flows out during the rainy period in the late fall to early summer. About 10 years ago aligator weed got started growing along the banks. This aquatic plant works well cleaning the water and supplying oxygen, as well as cover for young fish and crawfish. The weed is starting to clog the lake now and I can't seem to stop it with rodeo, 2 4 D, or diaquat. Does anyone have any suggestions or have been successful killing this stuff. We have a lot of large bass and I don't want to harm them. Frank
