Invasive Fish Removal Helps Restore Lake Mattamuskeet
Lake Mattamuskeet National Wildlife Refuge in Hyde County is removing thousands of invasive fish in an effort to restore water quality and aquatic grasses.

An increase in nutrients and sediment flowing into the 40,000 acre coastal lake led the N.C. Department of Environmental Quality to list the waterbody as impared in 2016. The problem is compounded by an influx of common carp, a fish that stirs up phosphorus, nitrogen, and other nutrients as it scavenges the lakebottom for food. This increases the turbidity of the water and has led to a decline in submerged aquatic vegetation. Aquatic grasses provide habitat for fish and crabs and food for migratory waterfowl.
