Hernando Point is a freshwater site located at Arkabutla Lake, United States, primarily utilised for snorkeling practice. The site features a gently sloping sandy entry from the shore, making it accessible for beginners. Divers and snorkellers should expect mild currents and low visibility, which characterises the underwater environment. The habitat supports various temperate freshwater fish and aquatic vegetation typical of the region. Facilities at the site include showers for visitor use. Typical sessions last approximately 30 minutes. Due to the limited visibility, this site is rated 1/5 for snorkelling, focusing more on observing shallow-water lake bed textures than extensive wildlife viewing.

Old Coldwater Townsite consists of the submerged remains of a former settlement, now located within Arkabutla Lake. The site is a freshwater wreck location featuring structural ruins from the original town. Due to the depth, which reaches up to 17 metres, and the prevalence of low visibility, the site is considered suitable only for advanced divers. Snorkelling is generally not recommended as the ruins are difficult to view from the surface. Access to the site requires a boat. Divers should be aware of potential entanglement hazards associated with the submerged structures.
