THE CURRENT PICTURE

Level against normal pool

The latest daily mean elevation is 532.80 ft. The conservation pool listed by TWDB is 535.00 ft (NGVD29; metadata dated Oct 22, 2026), putting the lake 2.20 ft below that reference.

Conservation storage is 149,093 acre-feet against a conservation capacity of 163,064 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 2.20 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

Grapevine Lake: the details

Is Grapevine Lake full?

As of Oct 22, 2026, Grapevine Lake is 91.4% full based on conservation storage. Its daily mean elevation is 2.20 ft below the current conservation pool of 535.00 ft. Percent full excludes flood-pool storage.

How low is Grapevine Lake right now?

The latest available daily average is 532.80 ft on Oct 22, 2026, 2.20 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 Grapevine Lake has been?

The lowest recorded elevation in the TWDB observations available to this site is 521.78 ft on Dec 28, 2006. The record used here runs from Oct 27, 1989 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 Grapevine Lake rising or falling?

Grapevine Lake fell 0.20 ft in seven days. The 30-day change is +0.12 ft. These changes compare daily average elevations on exact dates, rather than instantaneous measurements.
