THE TEXAS RESERVOIR BULLETIN DAILY FIELD REPORT
Lewisville Lake Level
Updated · Daily average · TWDB
Lewisville Lake is 3.91 ft below normal conservation pool and fell 0.27 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 518.09 ft. The conservation pool listed by TWDB is 522.00 ft (NGVD29; metadata dated Oct 22, 2026), putting the lake 3.91 ft below that reference.
Conservation storage is 462,531 acre-feet against a conservation capacity of 563,228 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 3.91 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.
