Northbrook Power Water Levels

Lake Summit Water Levels


Current Level is: 98.98 as of 08:15 on 2019-10-16



On October 08th, 2019 from 07:00 to 11:00, we will be conducting a test release of 1-unit at 100% gate. We will be performing this flow test for the upcoming Green River Race on November 2nd, 2019.

Caution: Do not enter the tailrace section directly below hydroelectric stations. These areas are prone to a sudden rise and violent turbulence in the water. Please remember to stay 300 feet away from the upstream and downstream sides of the dam and powerhouse.

Note: Scheduled flow releases are subject to variability based on natural conditions and/or unexpected changes in hydro project operation. Northbrook Energy may, at any time and without prior warning, modify the scheduled flow releases which may affect water levels, water availability and arrival or recession times.

Check special messages on the Current Lake Levels Web page for changes to recreation releases.
