Weeds in the duck hole

We were wrong... not a speck of duckweed, a few handfuls of hyacinth, sedges around the edges and Copious amounts of Giant Salvinia. Salvinia coverage of the hole doubled in a week. We planned on spraying for hyacinth because the surrounding area is pretty choked with it and would like to open up an alternate boat run. After researching chemicals I think the amine salt of 2,4D was our best/cheapest candidate for the hyacinth. I did the same for salvinia and came up with glyphosate as the best/cheapest way to go. Anyone ever done this? What formulation of glyphosate for salvinia? Any one know where I can find some of those weevils LSU spent $10 million or whatever on? Won't glyphosate kill nearly all aquatic life (crawfish)? Any ideas/ thoughts would be appreciated. Thanks in advance.

There are aquatic safe versions. The Glyphosate is safe, it's the surfactant that can be dangerous to aquatic life. Tractor supply sells it at the best price I've seen...
