Gemini Springs is composed of three springs that create two separate elongated pools and flows into an impounded reservoir. Rosenau et al. (1977) described the springs as originating in “sharp little ravines or clefts at the base of a higher surrounding area…” An eight inch diameter well was drilled to augment the flow from the springs (Rosenau et al., 1977). One pool is completely inundated by tannic reservoir water and measures 32 ft (9.8 m) long and 10 ft (3.1 m) wide. No boil or flow is detectable. The run is also inundated. The second pool is 100 ft (30.5 m) to the east and is situated on slightly higher ground than the first pool. This pool is 17 ft (5.2 m) long, 12 ft (3.7 m) wide, and 2 ft (0.6 m) deep. Clear water prominently boils from a small hole in the exposed limestone. Clumps of green and brown algae cover most of the sand spring pool bottom. Water also seeps from the hillside. The spring run is 6 ft (1.8 m) wide and 0.4 ft (0.1 m) deep. Algae, similar to that in the spring pool, grow in the spring run. The run flows 150 ft (45.7 m) east under a wooden bridge and joins the first spring’s inundated run. From the reservoir, spring water flows 1.5 miles (2.4 km) east into Lake Monroe. The surrounding higher ground rises west and north to more than 20 ft (6.1 m) above the water level. The springs are located within a Gemini Springs County Park with trails and playgrounds. During the February 2003 visit, swimming was prohibited due to high bacteria levels in the water. The average discharge between 1966 and 2000 was 10.1 ft3/s (6).
