Medina Lake is 26.8% full as of Nov 5, 2026, per the Texas Water Development Board; the USGS gage reads 1,018.6 ft, 45.6 ft below full pool.
Is that normal for the date?
At 1,018.64 ft, Medina Lake is lower than 69% of Novembers in 29 years of daily record.
The median for this date across 29 years is 1,046.55 ft, so this is -27.91 ft against the lake’s own history. Placed on a quantile ladder built from 9,838 daily readings published by USGS for site 08179500, 1997-08-09 to 2026-08-06. This reservoir typically peaks in January and bottoms out in December.
Medina Lake today: level, trend, source and access
Level against full pool
On Nov 5, 2026 the surface sat at 1,018.6 ft, 45.6 ft below the full-pool mark of 1,064 ft. The Texas Water Development Board rates its conservation storage at 26.8% full. Of the 15 Texas lakes on this site with a live percent-full reading, it ranks 14 of 15.
Trend
Between Oct 7 and Nov 5 (29 days) the level fell 2.1 ft, about 0.5 ft a week. The high in that window was 1,020.7 ft on Oct 7 and the low was 1,018.6 ft on Nov 5. In the last 7 days it fell 0.3 ft. The last 24 hours moved it down 0.07 ft.
Data source
The elevation comes from USGS monitoring location 08179500 (lake surface elevation above NGVD 1929, parameter 62614), last reported Nov 5, 2026. Percent full is the Texas Water Development Board daily storage estimate for the same lake. Feet from full pool, the trend and the figures above are computed from that reading and the published full-pool elevation; none is typed by hand. Bexar-Medina-Atascosa Counties WCID runs the dam on the Medina River.
Recreation status
Status: low. At 26.8% full it is 8.2 points under 35%, where many ramps end above the waterline and stumps, sandbars and rock shelves show. Call Bexar-Medina-Atascosa Counties WCID before you tow a boat there. If the 30-day pace of 0.5 ft a week down held, the surface would be near 1,016.6 ft in four weeks. Releases and rain change that quickly.
Check an elevation against full pool
For readers outside the U.S., the surface of Medina Lake is about 310.5 m above sea level, and full pool is about 324.4 m.
Check any elevation yourself. Type a level in feet above sea level (a ramp cutoff, a marina mark) to see how far it sits below full pool and in meters.
