Bloomington Lake to Disappear for Winter in Effort to Combat Invasive Weed

Normandale Lake is disappearing for the winter.

Officials with the Nine Mile Creek Watershed District and the City of Bloomington are getting aggressive about getting rid of the curly leaf pondweed there.

It's an invasive weed that grows rapidly, overtakes the native plant population and causes algae growth.

The plan is to drain the lake into Nine Mile Creek in hopes the harsh Minnesota winter will freeze the sediment bed and kill the invasive weed.

The lake will then be filled back up again in the spring.

Area wildlife should survive the change. 

The fish are expected to travel downstream as the water levels drop and wind up in the creek connected to the lake.

Special fences or guides for turtles have also been installed around the edge of the lake.

"It gives them a barrier so they don't go on the roads," said Erica Sniegowski of the Nine Mile Creek Watershed District.

"They'll follow that fence around to an opening we've left so they can go downstream and find a wintering habitat."

The cost of the initial phase of the project is expected to be about $370,000. 

Sniegowski said the technique has worked on at least two other lakes in Eden Prairie.
