Flow Releases at Canyon to Be Reduced
CANYON LAKE, Texas — Beginning Tuesday Sept. 5, 2017, current releases of 110 cubic feet per second (cfs) at Canyon Reservoir will be reduced to match the inflow of about 60 cfs at Spring Branch.
Recent rainfall produced by Hurricane Harvey in areas of the basin, including New Braunfels, did not increase flows in the river above Canyon Reservoir and the level of Canyon did not significantly increase. At 906.93 mean sea level (msl), Canyon Reservoir remains approximately two feet below its conservation pool of 909 msl and the inflows at Spring Branch, at 60 cfs, also are low. Given these factors, operational procedures for Canyon Reservoir require the reduction in flow releases.
These lower flows will remain in effect until Canyon’s level rises above its conservation pool of 909 msl. However, minor daily adjustments may occur to meet regulatory requirements.
