About this reservoir

Bull Run Lake Near Brightwood

Bull Run Lake is located in the Mount Hood National Forest near Brightwood, Oregon. The lake, which has a surface area of approximately 6,600 acres, is the primary drinking water source for the city of Portland. The Bull Run Watershed, which includes the lake and surrounding area, was established in 1892 to provide clean water to the growing city. The lake is fed by snowpack from the surrounding mountains and has a controlled release system to maintain water levels. The watershed is managed by the Portland Water Bureau, and access to the lake is limited to approved activities and individuals. There are no agricultural uses in the area, and recreational activities are also limited to protect the water quality. The lake and surrounding area provide habitat for a variety of wildlife, including fish, amphibians, and mammals.

FAQ

About Bull Run Lake Near Brightwood

Where does the data for Bull Run Lake Near Brightwood 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.
