Stillhouse Hollow Lake water level

What this level means

The level comes from gauge 08104050, Stillhouse Hollow Lk nr Belton, TX, and carries the time it was taken. Conservation capacity is 229,796 acre-feet. The agency sets full pool at 622.0 ft. The top of the dam sits at 698.0 ft. The Corps of Engineers puts the top of the flood pool at 666.0 ft. Over the record shown on the level page the gauge has moved between 619.33 ft and 626.32 ft (low on 2026-04-01, high on 2026-05-30). That put the reservoir at 98% of its conservation capacity. The last value stored here, 621.31 ft, is from 2026-09-09. Water level decides what is usable on the shoreline, from beach width to ramp access.

How this reading is taken

USGS gauge 08104050 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 Stillhouse Hollow Lake is 622.0 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.
