Willow and Granby update

Post By: klamb      Posted: 5/24/2013 4:42:47 PM     Points: 396    
Hi all,

It's Memorial Day weekend and time to kick off my annual communications about run-off.

Some of you might have noticed that we saw some peaking run-off at Willow Creek last week. Inflows to the reservoir were over 900 cfs. As a result, releases from the dam were bumped up to about 450 cfs on May 16th. They did not stay at that level for long.

Going into Memorial Day weekend, inflows from snow melt are anticipated to peak at about 700 cfs. Releases have been adjusted to around 100 cfs as we continue to store behind the dam. We do not plan to increase releases until the reservoir fills or we see much larger peak inflows.

Meanwhile at Granby Reservoir, we continue to release around 70 cfs. The reservoir is at a water level elevation of 8230.5--about 50 vertical feet down from full and the storage content is a little less than half full. The reservoir has started filling with some run-off flows already, bumping up ten feet in elevation over the past couple of weeks. We are anticipating seeing the reservoir water level rise another 20 feet as run-off continues.

Please let me know if you have any related questions.

Have a great and safe Memorial Day weekend.

Thanks for the update, it's a good thing for the fishery that we are getting nutrients coming in from Windy gap. although 50' down now the water conditions will be healthier for the fishery with plankton levels rising compared to the sterile water conditions that multiple high water years create. Now if we can just get some fish stocked!!
