From email from Reclamation (Kara Lamb):
We have a little more maintenance to do on the power arm of the Colorado-Big Thompson Project starting top of next week. While we’re doing some testing at the Flatiron Power Plant, we will drop Pinewood down as we move water out and also suspend pumping to Carter Lake. Residents around and visitors to Pinewood Reservoir should notice the reservoir elevation going down the end of this week. By Sunday or Monday, March 24 or 25, the reservoir could get down to an elevation of 6562 feet, perhaps just a little lower. However, that is not low enough to impact local water provision to the community around Pinewood. The pump to Carter Lake will go off during that same time frame, returning to service by Thursday, March 28. The reservoir has come up quite a bit over the past several weeks. It is currently around 75% full.
While these operations are underway, water will continue being delivered to Horsetooth Reservoir. Water to Horsetooth will drop Flatiron Reservoir down between Tuesday and Wednesday of next week. Flatiron fluctuates daily, but visitors to that reservoir might notice a lower water line than typical for this time of year.
Pinewood Reservoir is expected to start rising again on Tuesday, March 26 and should be back to a typical water elevation for this time of year by Thursday, March 28. Flatiron should start going up again by Friday and be back to a more typical water elevation by the last weekend of March.
From email from Reclamation (Kara Lamb):
Downstream demands on the Colorado River have been fluctuating quite a bit the last two days. Yesterday we dropped down from 145 cfs to 120 cfs. Today, March 19, we dropped again from 120 to 100 cfs. This might help us store a little water behind Green Mountain Dam. The reason for these changes is that the Shoshone Power Plant has a relaxed call on the river and part of the Green Mountain water right is in effect.
