Recent rainfall across Central Texas and the Hill Country has given Canyon Lake a noticeable boost, raising the reservoir to its highest level in months as summer recreation season gets underway.
New data from Water Data for Texas and the U.S. Army Corps of Engineers shows Canyon Lake was 61.2% full as of 8 a.m. on Thursday, June 18. The reservoir stood at an elevation of 888.19 feet above mean sea level and contained approximately 231,977 acre-feet of water.
The increase follows a week of storms that brought widespread rainfall to much of the region. On June 11, Canyon Lake was 58.9% full and held 223,306 acre-feet of water. Since then, storage has increased by roughly 8,700 acre-feet, pushing the lake more than 2 percentage points higher in just seven days.
Water levels have steadily climbed throughout the week. Canyon Lake measured 60.9% full on June 16 before rising to 61.1% on June 17 and reaching 61.2% Thursday morning.
Current inflows into the reservoir measured 334 cubic feet per second shortly after midnight on Friday, while outflows were significantly lower at 81 cubic feet per second as of 7 a.m. No surcharge releases were being made from Canyon Dam.
The latest reading also marks an improvement from a month ago, when Canyon Lake was 58.7% full. The year-over-year comparison is even more dramatic. At this time last year, the reservoir was just 46.9% full and held approximately 177,588 acre-feet of water in June 2025.
As of Thursday, June 18, Canyon Lake sits at elevation 888.19 feet above mean sea level and is 61.2% full. While recent rains have helped replenish the reservoir, it remains below its conservation pool capacity of 378,781 acre-feet. At its current level, Canyon Lake contains about 231,977 acre-feet of water, leaving it roughly 147,000 acre-feet below full conservation storage.
For boaters planning a trip to the lake, three public boat ramps remain open, the Water-Oriented Recreation District of Comal County tells MySA.
As of Thursday, June 18, the following ramps were open:
