Northern Water has determined it is time to initiate the second spill operation this season at Lake Granby. Outlet releases are being increased throughout today until outflows reach 1,500 cfs. We will maintain this release until at least next Monday. We are watching the skies this week – rainstorms are in the forecast and a significant rainfall event might prompt us to boost outflows even more.
At Willow Creek Reservoir, our West Slope operators will allow the reservoir elevation to rise to 8,129 feet this week. The high runoff this year generated a lot of debris which is now floating on the surface of the reservoir. The operators will adjust both the river outlet works and the gates on the pump canal. Prevailing winds should then help force the debris to move to the northeast corner of the reservoir where it can be removed. Once this operation is complete, the reservoir will be returned to its normal operating elevation of 8124 feet.
