THE TEXAS RESERVOIR BULLETIN DAILY FIELD REPORT
Falcon Lake Level
Updated · Daily average · TWDB
Falcon Reservoir is 40.15 ft below normal conservation pool and fell 0.30 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 261.05 ft. The conservation pool listed by TWDB is 301.20 ft (NGVD29; metadata dated Oct 22, 2026), putting the lake 40.15 ft below that reference.
Conservation storage is 318,225 acre-feet against a conservation capacity of 1,562,367 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 40.15 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.

COMMON QUESTIONS
Falcon Reservoir: the details
Is Falcon Reservoir full?
As of Oct 22, 2026, Falcon Reservoir is 20.4% full based on conservation storage. Its daily mean elevation is 40.15 ft below the current conservation pool of 301.20 ft. Percent full excludes flood-pool storage.
How low is Falcon Reservoir right now?
The latest available daily average is 261.05 ft on Oct 22, 2026, 40.15 ft below the conservation pool. This is an elevation in the source's NGVD29 datum, not the water depth at a dock or boat ramp.
What is the lowest Falcon Reservoir has been?
The lowest recorded elevation in the TWDB observations available to this site is 235.12 ft on Feb 16, 1957. The record used here runs from Jul 2, 1954 to Oct 22, 2026, starting once the reservoir first filled. Early observations may be less frequent than daily; this is not an instantaneous or guaranteed all-time minimum.
Is Falcon Reservoir rising or falling?
Falcon Reservoir fell 0.30 ft in seven days. The 30-day change is +0.45 ft. These changes compare daily average elevations on exact dates, rather than instantaneous measurements.
