About this reservoir

Rockport Reservoir

Rockport Reservoir is a man-made lake in Summit County, Utah, which was created in the 1950s by the construction of Wanship Dam. It is situated at an elevation of 6,050 feet and has a surface area of 1,080 acres. The reservoir's primary source of water is the Weber River, which is fed by snowmelt from the Wasatch Mountains. The reservoir provides water for irrigation, municipal, and industrial uses, and also offers recreational activities like fishing, boating, and camping. The reservoir's water level is regulated by the Weber Basin Water Conservancy District, which manages the snowpack providers and surface flow of the reservoir. The reservoir provides a crucial water source for agriculture and municipal uses in the surrounding area, contributing to the local economy and enhancing the quality of life for residents.

FAQ

About Rockport Reservoir

Where does the data for Rockport Reservoir 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.
