Lake Scanewa Near Kosmos reservoir
Lake Scanewa Near Kosmos
Lake Scanewa is a man-made reservoir situated near Kosmos, WA, in Washington. It was created in the 1960s as part of the Mossyrock Dam hydroelectric project, which aimed to provide electricity to the region. The lake is fed by the Cowlitz River, which is a significant source of hydroelectric power for the area. The primary surface flow providers to the lake are the Cowlitz River and the Tilton River. The lake's water level fluctuates due to the snowpack in the surrounding mountains, which serves as a source of water for the region. The lake has been utilized for various recreational purposes, including fishing and boating, and plays a crucial role in supporting local agriculture. The reservoir is home to several fish species, including salmon and steelhead, and is a popular destination for anglers.

About Lake Scanewa Near Kosmos
Where does the data for Lake Scanewa Near Kosmos 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.
