The Lake Charles State Park is a state park and recreation area in Powhatan, Arkansas. It is touted for being the first of its kind and size in the country upon its creation in the 1960s.

The Lake Charles State Park started out as a watershed/flood protection project near the Black River. However, the Small Watershed Act came into the horizon and gave the creators of the state park a new concept, leading to the construction of the Lake Charles State Park.

Named after Charles C. Snapp, a former District Director of the Lawrence County Conservation District, the 645-acre Lawrence Lake was completed in 1967. The opening of the state park followed shortly. Today, it offers camping, fishing, picnicking, boating, swimming, and hiking opportunities to its visitor. There is also a nature center and interpretive programs offered and available at the site.
