Areas of Coleto Creek Park to be closed for treatments
The aquatic herbicides Navigate and HardBall will be applied in selected coves of Coleto Creek Park and the Lake Wood Subdivision Park located on the Coleto Creek Reservoir on Monday for control of Watermilfoil.
The application is part of the Guadalupe-Blanco River Authority's ongoing Coleto Creek Reservoir Aquatic Plant Management Program.
This annual program was originally developed by GBRA after extensive study and public input from the Coleto Creek Aquatic Plant Management Advisory Committee, Park Chief Ranger Wilfred Korth said in a news release.
The program consists of an Integrated Pest Management system to help control nuisance aquatic vegetation overgrowth in the Coleto Creek Reservoir, located between Victoria and Goliad off U.S. Highway 59.
The main goals of the Coleto Creek Aquatic Plant Management Program continue to be to control the density of nuisance aquatic plants in the high use park areas of Coleto Creek Reservoir.
Korth said all treated areas in the Coleto Creek Reservoir will be clearly marked with signs.
Swimming or water contact recreation activity will not be allowed Monday in treated areas of the Coleto Creek Park and the Lake Wood Subdivision Homeowner's Park.
Only 24.6 acres of the reservoir will receive herbicide treatments. The additional 3,075.4 acres of reservoir will remain open for fishing, swimming and all normal recreation activities during this period.
Although more than 500 acres around the reservoir are impacted by nuisance aquatic plants, Korth said, the treatment to 24.6 surface acres "will keep the shoreline areas around these parks open for swimming, boating, shoreline fishing and general water contact for all park users through the summer months."
Watermilfoil and other non-native aquatic plants were originally brought to the United States for use in aquariums and water gardens.
