Where has all the grass gone in the lakes? My good friend whos been fishing all hi life says that texas A&M has developed a chemicle that kills grass in lakes and they have been spraying it for a couple years. I guess killing the grass makes managing power plants and othe equipment easier, but doesnt that create a problem for the ecosystem in fresh water? I know for sure that it makes it harder to find bass! If anyone knows about chemicles put into fresh water lakes to kill grass, let me know if its a permanant kill off, or if it will ever grow back if the chemicles aren't use anymore.....

the lakes are too low for it to grow. where it normally is, is dry land.

If it was there before, it will normally grow back at some point provided the chemical treatments stop. Problem is that it's not just chemicals. The grass carp population plays a bigger role in my opinion. Spraying costs a lot of money and the bigger the lake, the more money, or they have to take a more concentrated approach vs spraying the whole lake. In other words, areas around docks and ramps can be sprayed but other areas can be left alone. With grass carp, they drop them off and they systematically wipe out the grass in the whole lake. Plenty of examples of that scenario over the years. The gras carp munch away for years and the grass has a tough time trying to re-establish itself.

True to some degree, but some grasses can grow out to depths of 12-15 ft. Maybe some lakes that are 12-15 ft low have this issue but lakes with water levels only 4-6 ft low have other issues causing the decline.

Grass carp are doing a job on Austin right now, that's for sure.

I know of a algacide that a guy from A&M is trying to get on the market but it only kills algae and stays in suspension longer for more control. I'm around the fisheries department at a&m a lot and work with one of the aquatic herbicide suppliers in Texas. Don't know of any new aquatic herbicides being developed at a&m. There are already several herbicides on the market that kill aquatic vegetation.

Several factors affect how vegetation grows( water level, water visibility, nutrient loads, ect..) The amount of vegetation can vary from year to year.

Man I guess all the industries that depend on lakes for a source of water really hate grass. I don't know of an angler that hates grass besides the crazy ol coot at the dock that complains every time he throws a rattletrap right in the middle of it.
