Canyon Dam and Reservoir

• Canyon Dam and Reservoir is a joint project between the U.S. Army Corps of Engineers and the Guadalupe-Blanco River Authority. Located on the Guadalupe River, Comal County, the dam was built for two reasons:
  1) to control flood events that originated in the watershed of the Guadalupe River in the Texas Hill Country.
  2) for GBRA to have a stored supply of water available for citizens in the Guadalupe River Basin during times of drought.
• Canyon Reservoir holds 8230 acre-feet of water at normal level (909 msl*).
• When the Reservoir is over 909 msl, the Corps regulates how much water is released from the lake.
• When the Reservoir is 909 msl or below, GBRA regulates the discharge.
• The top of the dam is at 974 msl.
• The top of the emergency spillway is 943 msl.
• Various parks are located around the reservoir, and are operated by the corps.
