Canyon Lake was at 96.7% of conservation storage on Oct. 24, and its elevation was 907.42 feet, 1.58 feet below the conservation pool.
The Texas Water Development Board reports the percentage, while the U.S. Army Corps of Engineers reports the elevation. The Corps reading was taken at 11 p.m. CDT.

Comal County residents tracking dry conditions can compare that lake reading with a county drought index average of 569, up four points from the previous day. The Texas A&M Forest Service’s county reading ranged from 309 to 684. Its Keetch-Byram Drought Index runs from zero for saturated soil to 800 for extreme drought; the county average is a soil dryness measure, not a lake-level measure.
The Corps also reported that the lake elevation fell 0.04 foot over the preceding 24 hours. Its conservation pool tops out at 909 feet, giving residents a reference point for the Oct. 24 elevation. These figures are dated measurements; they do not establish a change in any water-use restriction.
The Edwards Aquifer Authority reported a J-17 index-well 10-day average of 639.3 feet above sea level and a Comal Springs 10-day average flow of 148 cubic feet per second on Oct. 24. Those averages describe aquifer and spring conditions over ten days, rather than the lake’s storage on a single day. Residents can check the authority’s current conditions page for later readings.
