Lake vegetation treatment expected later this week

 

  Aquatic Ecosystems Consultants, LLC, will be handling an application of vegetation management chemicals in Storm Lake, planned for Thursday morning. 

  Early this year, the Lake Improvement Commission approved a vegetation management plan suggested by the Iowa Department of Natural Resources.

  “This stems from a plan the DNR put together with the LIC to address the overabundance of vegetation in some of the high use shoreline areas over the last couple of years,” said DNR Fisheries Biologist Ben Wallace. While the lake has not seen a large amount of algae so far this spring, the contract was already in place. He said a modest amount of herbicide will be used, and likely no additional application will be needed this year.

 The project also represents a financial partnership. The DNR purchased the chemicals, and the local LIC is covering labor cost for applying it, according to Wallace.

The application includes Tribune brand herbicide with the active ingredient Diquat dibromine. It is designed for aquatic application and targets rooted vascular plants. The application also includes Komeen brand herbicide that has been proven effective on a number of submerged and floating aquatic plant species, with active ingredient copper ethylenediamine complex. “People are familiar with copper sulfate – we’ve used it for a long time,” Wallace said. “It gets diluted very quickly as it enters the water and begins to break down almost immediately.”

 There are no restrictions on water activity due to the chemicals. It is considered fully safe for swimming and consumption of fish, according to the DNR. If anyone is in the water in the immediate application areas, they will be asked to exit the water temporarily while the application is taking place.

 In general, the lake’s health is good this season.

  “It is pretty turbid [dark water with suspended sediment] however, more so than I would like to see,” Wallace said. “The wind has really churned things up. I can’t remember another spring into early summer where the wind has been blowing so hard almost every single day. I would really like to see it clearer.

“The walleye population looks good, the fish population in general looks real good,” Wallace added. “If we keep seeing things this turbid, though, I expect that the bluegill and largemouth bass might start to suffer.”
