Scott Dam reservoir
Scott Dam
Scott Dam is a concrete gravity dam located in Mendocino County, California, USA. It was built in 1922 by the Pacific Gas and Electric Company for hydroelectric power generation and irrigation purposes. The reservoir created by the dam, Lake Pillsbury, has a capacity of 82,000 acre-feet and is fed by the Eel River and its tributaries. The hydrology of the area is influenced by the Mediterranean climate that brings wet winters and dry summers. Surface flows in the Eel River are mainly from rainfall, while snowpack in the winter months is a significant source of water supply. The area surrounding the Lake Pillsbury is used for recreational activities such as camping, fishing, and boating. The reservoir also provides water for agricultural use in the nearby vineyards and orchards.

About Scott Dam
Where does the data for Scott Dam 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.
