The refuge's diversity of habitats supports waterfowl, wading birds, shorebirds, and songbirds. Although it is protected by a levee, the refuge provides flood storage in periods of high water.
Clarence Cannon Refuge is managed by Great River National Wildlife Refuge.

Refuge staff focuses its management on 2,200 acres of seasonal wetlands and semi-permanent and permanent marshes. A diverse program of water level and vegetation manipulations provides a wide variety of habitats.
A pumping station allows for water management on all wetland units, semi-permanent marshes, and green tree reservoirs (bottomland forests with large, cavity-ridden trees). A levee around the perimeter of the refuge provides protection from the Mississippi River until the river reaches six feet above flood stage. At this stage, a newly constructed spillway allows for water to flow into the refuge, flooding the entire interior of the refuge except for the headquarters site.
Upland vegetation is controlled and manipulated by burning, discing, farming, and mowing.
