- Water from 2,000 square miles of farmland flows through the refuge; thus, sedimentation has been a problem for bottomland hardwood trees and the lake. The average depth of the lake is now three feet. There are three Corps of Engineers tainter gate structures on the refuge managed to try and lessen the sedimentation problem. The refuge was and is an important area for migrating/wintering waterfowl and neotropical birds in the Lower Mississippi River Ecosystem. The lake is a popular fishing spot for area fishers.
Recreation - In amongst the obvious uses of the refuge such as bird-watching, with bald eagle and osprey nests, concentrations of wintering and migrating ducks and wildlife observation, there are many other functions we serve; bow hunting for deer, squirrel and raccoon, fishing, frogging, boating and others are available as well.
