Somerville Lake water level

What this level means

Readings come from station 08109900 (Somerville Lk nr Somerville, TX). The last value stored here, 237.04 ft, is from 2026-09-09. The agency sets full pool at 238.0 ft. Over the record shown on the level page the gauge has moved between 234.09 ft and 240.80 ft (low on 2026-04-01, high on 2026-06-20). That put the reservoir at 93% of its conservation capacity. Conservation capacity is 150,293 acre-feet. A low pool exposes stumps and mud in the shallow arms of the lake.

How this reading is taken

USGS gauge 08109900 measures the water surface and publishes the value continuously. This page stores the latest reading at build time and refreshes the record daily, so the figure above is a real measurement rather than a model or an estimate.

Full pool for Somerville Lake is 238.0 ft, so the gap between the reading and that number is what the reservoir is missing.

Elevations are given in feet above the gauge datum used by the operating agency. Two lakes are only comparable with each other through how full they are, not through their raw elevation, because each dam sits at a different height.
