Algae causing slimy problem at Centennial Park


The beauty of Centennial Park attracts a crowd of locals and visitors alike, but there is a growing, slimy problem at Nashville's most popular green space.

Lake Watauga, where people come to fish and feed the ducks, sits ridden with algae - trapping trash and ruining the view.

"It's not a good thing," said park visitor Kim Caruthers. "To me, it looks swampy and dirty."

The stuff looks and feels a lot like green cotton candy. Eventually, it will sink to the bottom of the nearly 116-year-old lake.

Those in charge know what caused it, but fixing it will take a lot of time and money.

"It's a problem that's been building up year after year after year," said Metro Parks Director Tommy Lynch.

This problem seems to get worse every year for one simple reason: rainwater supplies the lake, but it also brings along dirt and silt.

That buildup makes the lake more shallow and ripe for this kind of problem.

"It's not something that we're going to win the battle on a daily basis, by having a couple of our maintenance guys focus on it. The way that we're going to win this is implementation of the master plan," Lynch said.

The plan, that was unveiled last week, calls for dredging the lake to make it deeper. A fresh water supply should also keep things moving and make it better for the wildlife.

In the meantime, workers will treat the lake weekly, letting nature run its course while planning to help it along with some man-made plans.

The actual work could be months away. In the short term, Metro Parks will work with Metro Water to bring in additional aerators to inject more oxygen into the lake.
