2002 flood, the peak flow was about 70,000 cubic feet per second (2,000 m³/s). The amount of water that flowed over the spillway was about 3½ times the amount of water that the reservoir holds. Erosion over the course of three days washed away soil below the spillway to reveal what is now the Canyon Lake Gorge. Water continued to flow over the spillway for six weeks. Water conservation The Guadalupe-Blanco River Authority (GBRA) has rights to the water in the conservation pool of the lake. This water is used to operate several small hydroelectric plants downstream from New Braunfels and for municipal water supply, irrigation, and industrial uses. GBRA built a hydroelectric facility at Canyon Dam in August 1987; it was put into service in February 1989. Recreation Canyon Lake is a center for recreation in the area. The Corps of Engineers built and maintains eight park areas around the lake for camping, swimming, boating and picnicking. Bank fishing is available in all park areas, and a fishing dock can be found in Cranes Mill Park on the south side of the lake. Comal County provides several public boat ramps for access to the lake. Hike, bike and equestrian trails are available, as is limited hunting (archery only) and professional fishing guide services. PUBLIC ACCESS TO CANYON LAKE - Swimming and Boating The GPS coordinates given for a general search of 'Canyon Lake, Texas' on Wikipedia or available from a 'Google' search do not correspond to any public access areas. The only public access to the lake is at one of the parks, marinas or boat ramps around the lake. Although the Army Corps of Engineers owns and controls the shore immediately above the lake waterfront, the remainder of the lake shore (accessible by public roads) is privately owned property and public access to the lake shore through any of these properties is not allowed.

There are 2 marinas located on the lake. The marinas have boats and jet skis available for rent. There are several public boat ramps on the lake as well as private boat ramps. Public
