About this reservoir

E. V. Spence Res Nr Robert Lee

E.V. Spence Reservoir, located near Robert Lee, Texas, was constructed in the 1960s by the U.S. Army Corps of Engineers. The reservoir spans over 14,000 acres and is fed by the Colorado River. The hydrology of the reservoir is primarily influenced by the Colorado River basin, which is known for its high variability in flow. Specific surface flow providers to the reservoir include the North Concho and Middle Concho Rivers. Snowpack providers include the Rocky Mountains, although their impact on the reservoir is minimal. The reservoir provides water for agricultural purposes such as irrigating crops and livestock watering. Additionally, recreational activities such as boating, fishing, and camping bring tourists to the reservoir. However, in recent years, the reservoir has experienced a decline in water levels due to drought and overuse, leading to concerns about its sustainability.

FAQ

About E. V. Spence Res Nr Robert Lee

Where does the data for E. V. Spence Res Nr Robert Lee 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 above 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.
