About this reservoir

Lake Chelan At Purple Point At Stehekin

Lake Chelan at Purple Point in Stehekin, WA is a popular recreational area that has a rich history and unique hydrology. The lake is over 50 miles long and is fed by snowpack from the surrounding mountains, including the North Cascades. The lake's surface flow is primarily from the Stehekin River, which runs through the valley and into the lake. The snowpack providers for the lake include the North Cascades National Park and the Okanogan-Wenatchee National Forest. The area was historically used by the Native American tribes who fished and hunted in the area. Today, the lake is a popular destination for fishing, boating, and camping. The area also supports some agriculture, including orchards and vineyards.

FAQ

About Lake Chelan At Purple Point At Stehekin

Where does the data for Lake Chelan At Purple Point At Stehekin 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.
