Gillham Lake


Gillham Lake is known as the "Bright Spot on the Cossatot." Located in southwestern Arkansas, the lake is a dammed portion of the Cossatot River. The Gillham Lake project was approved to control flooding, the area’s water supply, and wildlife conservation efforts. The dam was completed in 1975. While recreation wasn’t in the initial plans for the lake project, it was later included. Today, the 1,370-acre lake attracts many for boating, hunting, and fishing.

Once set up at your campsite, head down the two-mile Coon Creek Walking Trail to take in the scenic lake views and colorful trees. Take your fishing pole out onto the lake or the fishing pier to catch bass, catfish, and even walleye. Drive or boat to remote areas of the park to hunt deer or turkey. Tired after a long day of driving? Relax over by the sandy swim beach at Big Coon Creek and dip your toes into the refreshing lake water.

There are three campground options on Gillham Lake. Big Coon Creek, Little Coon Creek, and Cossatot Reefs have a combined total of 73 campsites. Each park offers its own amenities from the swim beach at Big Coon Creek to the fishing pier at Little Coon Creek to the large picnic shelter at Cossatot Reefs. Reservations can be made in advance of your visit. Peak season runs from March to October.

Gillham Lake is just six miles from Gillham, Arkansas and can be accessed from County Road. The town of Gillham has food, services, and supplies for fishing and camping. A few miles separate the different parks on lake. Visitors may find the need to drive to amenities and activities at other parks such as the swim beach or boat ramp.

If planning to fish during your visit to Gillham Lake, it’s unlikely you’ll leave disappointed. The lake has many crappie, catfish, bass, sunfish, and walleye beneath its surface. Bring a chair and cast a line from the fishing pier. If you brought a boat for your visit, use one of the boat ramps to find a quiet and remote spot further out on the lake.


Hunting is permitted in designated areas of Gillham Lake Project land. Hunters come to the area for turkey, rabbits, deer, and many other types of wildlife. Since hunting is allowed in mostly undeveloped areas, roads may be rough. Take extra caution while driving. Some hunting areas are far more remote and can only be accessed by boat. Check regulations and limits prior to hunting at Gillham Lake.
