Merrisach Lake COE camping near Tichnor Ar.

Worth a stop

The Dale Bumpers White River National Wildlife Refuge is a haven for wildlife and migratory birds, and is one of the largest remaining bottomland hardwood forests in the Mississippi River Valley. The National Park Services's Arkansas Post National Memorial is also a great place to visit while camping in the area.

Public land it sits in

On Wilderness Atlas →

Dale Bumpers White River National Wildlife Refuge begins about 4.4 miles away, and it is the closest of these.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

The Arkansas Post Canal creates a waterway from the Arkansas River to the White River, and Merrisach Lake stems from the pool between the Wilbur D. Mills Dam and Lock Number 2. Wilbur D. Mills Pool boasts 96 miles of shoreline and 10,600 acres of water.

Recreation

The campground and day use park offers visitors the perfect amount of seclusion to enjoy the outdoors. Visitors enjoy fishing for bass, crappie and catfish in Merrisach Lake and other tributaries of Pool 2. The tailwaters of Wilbur D. Mills Dam provide excellent opportunities to catch many species of gamefish, especially catfish. Visitors to this area also find great hunting, birding and boating opportunities. Merrisach sits on the famed Mississippi Flyway, where millions of songbirds, ducks, geese and butterflies pass during migration.
