Site details

New Mexico's largest lake, a 15,590-acre reservoir on the San Juan River in the state's northwest corner, with depths to 100 feet in the dived areas near the dam. Most diving is by boat from the state park marinas; walk-in entry is possible near the dam/spillway when the lake level is high, though it requires hauling gear down a steep hill. Visibility is modest (10-15 ft) and water ranges from the 40s F in winter to about 75 F in summer.
