THE TEXAS RESERVOIR BULLETIN DAILY FIELD REPORT
Lake Granbury Lake Level
Updated · Daily average · TWDB
Lake Granbury is 2.01 ft below normal conservation pool and rose 0.24 ft in seven days.
Elevation above the source's sea-level reference (NGVD29 -1.11). This is not water depth or a live reading.
THE CURRENT PICTURE
Level against normal pool
The latest daily mean elevation is 690.69 ft. The conservation pool listed by TWDB is 692.70 ft (NGVD29 -1.11; metadata dated Oct 22, 2026), putting the lake 2.01 ft below that reference.
Conservation storage is 117,260 acre-feet against a conservation capacity of 132,949 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 2.01 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.
