Old Wild Horse Dam Remnants features the partially submerged remains of a 1937 dam located near the modern dam at the north end of the reservoir. This freshwater site offers an artificial reef environment consisting of underwater structures and rocky crevices. Due to geothermal springs feeding the reservoir, water temperatures are high, ranging between 37°C and 57.8°C. The site is suitable for advanced divers due to the overhead environment presented by the dam remnants. Access is available via both shore and boat. Facilities provided at the site include parking, toilets, showers, and changing rooms. Snorkelling is possible, though rated 2/5.
