Surrounded by the Ouachita National Forest, Lake Ouachita is known for its scenic natural beauty and the clarity of its waters. These pristine waters form the largest manmade lake within Arkansas's borders. Named one of the cleanest lakes in America, 40,000-acre Lake Ouachita is a water sports mecca for swimming, skiing, scuba diving, boating and fishing. Angling for bream, crappie, catfish, stripers and largemouth bass can be enjoyed in open waters or quiet coves along the lake's 975 miles of shoreline.
