The Great Plains offers an entirely freshwater diving and snorkelling experience spread across reservoirs, lakes, and one underground mine. Site types range from artificial reefs and deliberately sunk wrecks to rock walls, ledges, and drift dives below dams. The fish life is distinctly inland: Carp, Blue Gill, Perch, Sucker, Catfish, and Channel Catfish are observed across the vast majority of sites, while Sturgeon, Pike, Walleye, and the prehistoric-looking Paddlefish reward those who look carefully. Sub-areas such as Bonne Terre Mine, Lake Tenkiller, and Black Hills Lakes each offer a different character, from flooded caverns to clear reservoir walls.

Across Great Plains's dive sites, May, June, July, August and September are most often reported as the best months to visit.
The Great Plains is rich in freshwater fish observed across many sites. Carp, Blue Gill, Perch, and Sucker are among the most frequently encountered, while Catfish and Channel Catfish are also common. Divers willing to explore more widely may come across Walleye, Pike, Large Mouth Bass, Small Mouth Bass, and the distinctive Paddlefish. Longnose Gar and Freshwater Drum have also been recorded at certain sites.
The majority of sites across the Great Plains are rated for beginners, including shore-entry artificial reefs, shallow ledges, and calm reservoir walls. Sites such as Boulder Haven, The Bowl, and Beaver Lake Dive Park are specifically noted as beginner-friendly. A smaller number of sites, including the drift dive at Tailrace, are rated intermediate and involve current management. New divers have a wide range of options to build confidence.
Each sub-area has its own character. Bonne Terre Mine offers a flooded underground mine environment unlike any open-water lake. Lake Tenkiller combines reefs, walls, wrecks, and artificial structures across a broad depth range. Black Hills Lakes provide a different landscape shaped by the surrounding terrain. Lake Oahe concentrates several beginner-friendly artificial reef and ledge sites in one area, including a dam site that suits both divers and snorkellers.
Shore entry is available at many sites across the Great Plains, making independent access straightforward for divers and snorkellers. Sites such as Blakely Mountain Dam, Little Rock Drop Off, and The Tower are all shore-entry locations. Some sites, including Hotel Island East and Lake Ouachita, require a boat to reach. Several sites in the region offer both options, so the choice of access depends on which sub-area and specific site you visit.
