Hey, What are They Spraying in the Lake?

Today, May 23 Aquatic Nuisance Control Inc. our herbicide applicators were out on the Main Lakes to conduct the Curlyleaf Pondweed treatment as prescribed. The Curlyleaf is topped out and ready to treat, just in time before the plant gets the chance to produce its reproductive structures called turions. The treatment maps are included below depicting the exact areas that were treated. The reason we aggressively target CLPW for eradication has been detailed in last season’s Blog. The goal of these treatments is to focus herbicide induced stress on the CLPW while causing minimum damage to beneficial natives in the vicinity.
Please notice on the overview map that it is terrestrial grass in front of Sunset Beach that was mapped for treatment. This terrestrial grass is submerged and is now presenting a nuisance to those wishing to use the beach. Beach areas are intended to be open to all recreational pursuit and therefore will be treated aggressively to accomplish this goal. Both of these herbicide applications will be contact herbicides (Reward and/or Aquathol K).

Here is the overview map detailing where Aquatic Nuisance Control will be treating CLPW and at Sunset Beach, submerged terrestrial grasses.


These patches are near the marina in East Lake. It is important to treat the CLPW before it produces reproductive turions. If a boat goes through one of these beds, it can transfer such turions to another location. This is one way the CLPW is spread. Since 2004, CLPW has been selectivly treated early in the season before turions develope.

Small patches of CLPW at the entrance to Finger Lake at Buchanan Road.


This patch of CLPW just south of the island in the west side of the Main Lake is the largest and most dense patch being treated.


A small patch of CLPW near the pump at W. Royal and Buchanan. Both pumps on the Main Lakes have CLPW near them. This is because the cold ground water supplied by the pumps favors the cold water loving exotic plant.
