in New Braunfels. The lake level is down almost 13 feet due to the broken spill-gate, however the body of water is still navigable in certain areas although hazards such as stumps and rocks are prevalent. Lake Dunlap offers mostly calm water due to its narrow size (in parts) and protection from wind by shoreline trees. Wakeboarders, skiers, and other recreational enthusiasts use Lake Dunlap daily due to its family friendly calmness, temperature, and status of near-private lake, however watersports since the dam broke are mostly limited to areas closest to the dam where the water is the deepest. Boaters have to proceed with caution as the lake has numerous unmarked stumps.

unexpectedly collapsed, nearly draining the lake by day's end. The lower, concrete portion of the dam remains in place. The collapse was due to ageing structural steel. The Guadalupe-Blanco River Authority worked with lakeside residents who formed an engineering and technical committee and a temporary water-control improvement district. Engineers and the Texas Water Development Board devised a solution to replace the spill gates at Dunlap and GBRA's other remaining aging dams. On November 3, 2020, the residents of Lake Dunlap voted on and passed three propositions which allow for the creation of a formal water-control district and assessment of
''ad valorem'' taxes that will fund the construction of a new dam. The construction of the new design is estimated to be completed in May 2023.
