Three reservoirs. One clear comparison.
Compare TWDB conservation storage and dated elevation changes. Each measure keeps its unit and source date.
| Reservoir | Reading date | Conservation full | Elevation | 7-day change |
|---|---|---|---|---|
| Lake Travis | 2026-09-28 | 89.6% | 674.77 ft | -0.80 ft |
| Canyon Lake | 2026-09-28 | 97.9% | 908.02 ft | -0.30 ft |
| Lake Corpus Christi | 2026-09-28 | 82.7% | 91.67 ft | -0.26 ft |
| Medina Lake | 2026-09-28 | 28.6% | 1020.63 ft | -0.33 ft |
Change uses the headline reading and an observation exactly 7 calendar days earlier. Missing comparison dates stay unavailable. Elevations have reservoir-specific references; they do not rank water supply or safety.
