About this reservoir

Crane Valley

Crane Valley is a picturesque valley located in California, known for its rich history and abundant natural resources. The valley is fed by several rivers and streams, including the San Joaquin River, and is surrounded by the Sierra Nevada Mountains. Its hydrology is primarily based on snowmelt runoff, and it has several surface flow providers, including the Merced River, the Tuolumne River, and the Stanislaus River. The valley is also home to several major snowpack providers, including the Yosemite National Park and the Sierra National Forest. The valley is used primarily for agricultural purposes, with many farms and ranches located in the area. Recreational activities such as hiking, camping, and fishing are also popular in the area, which is home to several popular state parks and wildlife areas.

FAQ

About Crane Valley

Where does the data for Crane Valley 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.
