About this reservoir

Jackson Meadows (Nevada Co Wd)

Jackson Meadows is a reservoir located in the Nevada County Water District of California. The reservoir was created in 1960 by the construction of a dam on the Jackson Creek, a tributary of the Middle Fork of the Yuba River. The hydrology of the area is dominated by snowmelt from the Sierra Nevada Mountains which maintains the water level of the reservoir. The snowpack provides a major source of water for agriculture, recreation, and hydropower generation. The reservoir is also used for recreational purposes like fishing, boating, and camping. The surrounding area is a popular destination for outdoor enthusiasts during the summer months. The reservoir is managed by the Nevada County Water District which ensures that it continues to provide reliable water supply to the area.

FAQ

About Jackson Meadows (Nevada Co Wd)

Where does the data for Jackson Meadows (Nevada Co Wd) 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.
