Lk Houston Nr Sheldon
LK Houston NR Sheldon, TX is a reservoir located in Harris County, Texas. It was created in 1953 by the construction of an earthen dam on the San Jacinto River. The reservoir has a total capacity of 21,000 acre-feet and serves as a source of drinking water for the city of Houston. The hydrology of the reservoir is influenced by the San Jacinto River and its tributaries. The surface flow is provided by the river and the snowpack providers are limited as the area does not receive significant snowfall. The reservoir is primarily used for municipal water supply purposes, but it also provides opportunities for recreational activities such as boating and fishing. There are no agricultural uses associated with LK Houston NR Sheldon, TX.

Is Lake Houston Near Sheldon 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 Houston Near Sheldon 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.
