re: Giant salvinia

The only things that help with giant slavinia are high water and cold winters with prolonged freezes (which are pretty rare these days). All of the other stuff they've tried has had little to no affect. Here's a picture of Caddo in Jeems Bayou from a couple of summers ago. It's some bad stuff.

Bistineau is wrecked with the stuff. Caddo has more open water and flushes better although parts of Jeems and the texas side have been thick too the last few years. If the weevils could tolerate the cold we might have a shot. Texas was trying to harden them to cold but I don't know how the program has progressed. South louisiana is likely far south enough that the weevils can overwinter. I know they've had success in parts of south central texas with weevil control. We need a 1983 type winter followed by a high water spring and some type of successful control program to get back to even against this stuff.
