Utah Lake reservoir
Utah Lake
Utah Lake is the largest freshwater lake in Utah, covering an area of about 148 square miles. The lake has a rich history dating back to the Native Americans who inhabited the region. The hydrology of Utah Lake is unique, as it is fed by several rivers and streams, including Provo River, Spanish Fork River, and Hobble Creek. The lake also receives water from snowpack in the surrounding mountains, with the spring snowmelt resulting in high flows into the lake.
The lake is crucial for agriculture in the Utah Valley region, with water from the lake used for irrigation of crops such as alfalfa and fruit trees. It is also a popular recreational spot, with activities such as fishing, boating, and swimming enjoyed by locals and tourists. However, the lake has faced challenges in recent years with pollution and invasive species such as carp and quagga mussels impacting the ecosystem. Efforts are being made to address these issues and preserve the lake for future generations.

Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Utah Lake
Where does the data for Utah Lake 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.
