MAMMOTH SPRING -- Mammoth Spring Lake at Mammoth Spring State Park was first drained three years ago when a new permanent water supply line was built at the National Fish Hatchery, close to the park.
The lake was drained again last year and this year in an effort to kill the dense aquatic vegetation (lake weeds) that grows in most all of the lake.
Mammoth Spring Park Superintendent Dave Jackson said the reason for such a high concentration of weeds on the lake is due to the high nitrogen content in the lake.
Jackson said the lake is usually drained in the coldest months of the year, usually January and February, in hopes freezing the vegetation will retard its growth.
"The largest problem with the vegetation is that it is unsightly and many visitors to the park do not find it attractive," the superintendent said. He added that as far as harming anything in the lake the vegetation is not a problem.
Jackson said the park system has mentioned hiring a Lake Management Consultant to look into the problem of the vegetation and that dredging the lake may be an option sometime down the road. He said that dredging the lake bed is about the only option open for getting rid of the plants.
Until the Arkansas Department of Parks and Tourism can come up with a solution to the vegetation, visitors to the park and local residents can see how the park looked before the dam at the park was built in 1888.
