Officials with the N.C. Division of Parks and Recreation say they will drain a 33-acre pond at the edge of Lake Norman this month for testing.
The pond is at a dam near Lake Norman State Park, and the drawdown of water will limit visitor access to the shorelines in the area.
State officials say researchers need to study sediments in the pond and conduct routine maintenance, to control weeds and improve the fishery. Refilling of the pond will depend on rainfall.
Hiking trails in the area will not be affected, officials say.
