Haynes Lake is a 45-acre freshwater lake and offers fishing. The lake is for stocked catfish, bream, and bass. A boat launch and parking are available. A Mississippi fishing license is required for all persons between the ages of 16 and 65 and may be purchased at the park office for a nominal fee. Water skiing is not permitted on Haynes Lake.
The water level in the lake can vary a great deal based on the time of year and the frequency of rain events. Without regular rain events, the water level will decline which can make access to the lake edge and boat launching difficult. Investigations have found that fractures have developed in the limestone lake bed. These fractures allow water to pass through the lake bed and leave the lake. The loss of water is in such quantities that traditional normal lake water levels cannot be maintained.
