BC-NE--Zebra Mussels-Omaha, NE

The U.S. Army Corps of Engineers plans to again draw down Glenn Cunningham Lake in north Omaha in an effort to control invasive zebra mussels and the overabundance of common carp. The Corps said in a news release Friday that the goal of the initial drawdown was to expose zebra mussels to freezing temperatures and eliminate the carp. Then came the heavy winter snows and the rain last month. The runoff caused officials to close a drain gate in order to minimize flood risks downstream.

OMAHA, Neb. (AP) — The U.S. Army Corps of Engineers plans to again draw down Glenn Cunningham Lake in north Omaha in an effort to control invasive zebra mussels and an overabundance of common carp.

The Corps said in a news release Friday that the goal of the initial drawdown was to expose zebra mussels to freezing temperatures and dry them out while also eliminating the carp to improve the fishery. The reservoir was lowered almost 20 feet by late November, and the lake bed was exposed to harsh winter conditions.

But snowmelt and runoff from heavy rain last month caused officials to close a drain gate in order to minimize flood risks downstream. The lake now sits only about 1.5 feet (0.5 meters) below normal.

The drawdown will begin shortly to ensure the lake is prepared for final fish renovation, which is tentatively planned for early June.
