Lk J. B. Thomas Nr Vincent
LK J.B. Thomas is a reservoir located near Vincent, Texas. The reservoir was created in 1952 when the Colorado River was dammed. The primary purpose of the reservoir is to provide water for irrigation and municipal use. The hydrology of the reservoir is supplied by the Colorado River and several small tributary streams. The specific surface flow of the reservoir is dependent on the amount of rainfall and runoff from the surrounding area. The snowpack providers for the reservoir are primarily from the northern and western parts of the state. The reservoir is used for agricultural purposes such as irrigation, and also for recreational activities such as boating, fishing, and camping. There are several parks and boat ramps located around the reservoir for public use.

Is Lake J. B. Thomas Near Vincent 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 Lake J. B. Thomas Near Vincent 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.
