Stillhouse Hollow Lk Nr Belton
Stillhouse Hollow Lake is a reservoir located in Bell County, Texas, near the city of Belton. The lake was created in 1968 by the U.S. Army Corps of Engineers for flood control and water supply purposes. The hydrology of the lake is fed by the Lampasas and Leon Rivers and has a surface area of 6,430 acres. The lake provides water to the cities of Killeen, Harker Heights, and Belton. The snowpack that feeds the lake comes from the northern parts of Texas and the Rocky Mountains. The agricultural use around the lake includes cattle grazing and row crops. Recreation activities on the lake include fishing, boating, camping, hiking, and swimming. The lake is a popular destination for outdoor enthusiasts in the Central Texas region.

Inside the reservoir
The real shoreline of this water body, with a depth model scaled so the basin holds exactly its recorded storage. Drag to orbit, scroll to zoom, and use the slider to drain and refill it. Click anywhere on the basin for the modelled depth there.
How this is built. The shoreline is the National Hydrography
Dataset polygon for this water body (“Stillhouse Hollow Lake”),
matched to the dam by proximity and confirmed by comparing its area with the
National Inventory of Dams surface area.
Depth is modelled, not surveyed: the basin is shaped by distance from
shore — deep in open water, shallow in the bays — and scaled so its
volume equals the recorded storage. No national bathymetric survey exists for
US reservoirs. Treat the shoreline, area and volume as measured, and the depth
distribution as an informed approximation.
Above normal pool, water is shown rising within the normal-pool
shoreline. Where it would actually spread depends on the surrounding
terrain, which is not modelled here — a reservoir in a steep canyon barely
widens, one on flat ground can spread a long way. This is a depth and volume
figure, not an inundation map. Official inundation mapping for a dam
comes from its Emergency Action Plan.
Plan around the weather

About Stillhouse Hollow Lk Nr Belton
What is the water level at Stillhouse Hollow Lake Near Belton Reservoir right now?
As of September 17, 2026, Stillhouse Hollow Lake Near Belton Reservoir is holding 621 ft, about 100% of normal for this date. Pool elevation and the year-over-year trend are shown above.
Is Stillhouse Hollow Lake Near Belton Reservoir high or low right now?
Compare the percent-of-normal figure on this page: above 100% means storage is higher than the historical average for the date (a wet year), below 100% means lower (a dry year or drought). The daily-levels chart shows the current trend.
Where does the data for Stillhouse Hollow Lake Near Belton come from?
Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.
What does the Hazard hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this reservoir, set a threshold, and you'll get a push the moment conditions cross.
