Aquatic spraying Glyphosate

Technicians from Citrus County's Aquatics Services Division spray the chemical Glyphosate mixed with water to treat lily pads in Lake Spivey in this 2013 file photo. 

Roughly 200 acres of invasive aquatic plants in and around the waters of Lake Rousseau will be the target of a multiday spraying operation by state wildlife officials next week. 

According to a news release from the Florida Fish and Wildlife Conservation Commission, or FWC, staff has scheduled to spray Hydrilla from June 11 to 12, weather permitting, but treatments could continue later into the week.

About 147 acres of Hydrilla will be treated just in marked boating trails on the 4,163-acre lake, including County Trail B, Shoreline B, County Trail C, Shoreline C and River Retreats Trail.

FWC will also spray 50 acres of floating plants throughout Lake Rousseau that have been flushed downstream by high flows of the Withlacoochee River into the center of the reservoir, specifically near the Silver Lake, Harnick Estates and Old Mill trails.

There are better options than manatees like bioherbicides and mechanical harvesting, but bottom line is chemical control is cheaper. Better still, get rid of the dam and restore the Withlacoochee river, then manatees would have historic access to rainbow springs and the hydrilla problem would go away.

Right--just kidding in previous post, but actually I do remember back in the day Manatees: Wake-Speed-Only signs in the Rainbow River and saw a few manatees at the confluence of the Withlacochee and the Rainbow. They would have a grocery store in those rivers now; however, the many power boats on those rivers would hurt or kill them--especially the speeders on the Withlacoochee. But I think fishermen should be warned to NOT eat any fish they catch after all of this spraying.

Why can't they just release about two dozen manatees for about a month into Lake Rousseau. It would be a win win win. Those sea cows would get in some good grazing in comfortably warm waters, no toxic chemicals would be releasted to kill fish, birdlife, turtles and frogs along with the aquatic plants, and there would be no carpets of dead aquatic plants smothering anything that's trying live on the bottom of the lake. Manatees are Nature's aquatic plant vacuum cleaners! I've heard of people using goats for weed eating, so why not manatees for aquatic plant eating?
