A spillgate failure at Lake Dunlap has mostly emptied the 410-acre reservoir on the Guadalupe River southeast of New Braunfels. The Guadalupe-Blanco River Authority said the peak river flow has subsided, but cautions homeowners downstream as “water flows will remain brisk.” The lake started draining after the failure at 8 a.m. Several floodgates have been releasing water along multiple waterways in the area after heavy rains caused flooding the last two weeks. Maximum depth of Lake Dunlap was 40 feet near the dam, and the lake was known for boating, water skiing and fishing.
