About this reservoir

New Bullards Bar

New Bullards Bar is a reservoir located in California's Yuba County. The dam was completed in 1970 with a height of 645 feet, making it one of the tallest earth-filled dams in the United States. The reservoir has a capacity of 969,000 acre-feet and is part of the Yuba River Development Project. It provides hydroelectric power and has a surface flow that feeds into the Yuba River.

The water supply for the reservoir comes from several sources, including snowpack from the Sierra Nevada Mountains, which is collected by the Yuba River and its tributaries. The reservoir also receives water from the North Yuba River, Middle Yuba River, and Oregon Creek.

New Bullards Bar Reservoir is used for both agricultural and recreational purposes. It is a popular spot for boating, fishing, and camping. The surrounding area is home to several campgrounds, parks, and trails. Additionally, the reservoir provides water for agricultural purposes in the Yuba County region.

FAQ

About New Bullards Bar

Where does the data for New Bullards Bar 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.
