Lake Elmer Thomas Dam is a freshwater shore dive with easy entry.
Lake Elmer Thomas Dam is a freshwater shore dive in the Wichita Mountains refuge, with simple dam-area entry and a shallow profile that makes it useful for practice and relaxed exploration. The upper water stays the most comfortable, while the lower layer can turn colder, darker, and siltier below the thermocline. Freshwater fish and the submerged dam structure are the main draw, so good buoyancy and surface awareness matter more than speed.

Safety Notes
Use a surface marker, stay clear of boat lanes, and expect buoyancy to matter once the water gets silted or colder below the thermocline.

Use the authorized dam-area entry for snorkeling and scuba; other refuge waters are off-limits and some access routes can involve Fort Sill screening.
Legal Notes
Commercial snorkeling or scuba instruction at Wichita Mountains Wildlife Refuge requires a permit.
Community notes to help plan your visit.
Scuba Diving
Good for training dives, buoyancy work, and relaxed freshwater exploration from shore.
Freediving
Not a primary freedive objective.
Snorkeling
Snorkeling is most useful near the dam and in calm surface conditions; it is a shallow freshwater outing, not a long swim.
