THE TEXAS RESERVOIR BULLETIN DAILY FIELD REPORT
O.H. Ivie Lake Level
Updated · Daily average · TWDB
O.H. Ivie Reservoir is 22.38 ft below normal conservation pool and fell 0.01 ft in seven days.
Elevation above the source's sea-level reference (NGVD29). This is not water depth or a live reading.
THE CURRENT PICTURE
Level against normal pool
The latest daily mean elevation is 1,529.12 ft. The conservation pool listed by TWDB is 1,551.50 ft (NGVD29; metadata dated Oct 22, 2026), putting the lake 22.38 ft below that reference.
Conservation storage is 227,519 acre-feet against a conservation capacity of 554,340 acre-feet. Percent full measures stored water volume; it is not the fraction of the lake's maximum depth.
What this means on the water
At 22.38 ft below conservation pool, shoreline and ramp conditions can differ from normal-pool maps. Check the managing authority's current ramp, closure and release notices. A reservoir-wide average cannot establish clearance at a specific location.
