From email from Reclamation (Kara Lamb):
With the recent heat, we are finally starting to see a dip in the elevations at Horsetooth and Carter reservoirs.
Today, Horsetooth is releasing about 360 cfs to water users (agricultural, city and industrial users). About 164 cfs is coming into the reservoir. It has started to go down and is at an elevation today of 5425. It will reach 5424 by tomorrow and will continue going down.
The pump to Carter went off in the middle of the night last night. Carter is approximately one foot below full at an elevation of 5758. With the heat, it is likely demand out of Carter will come up, too, and we’ll start to see the elevation there start to go down as well.
We are making deliveries down the Big Thompson River and along the canals. As we run water through the project, we are seeing regular fluctuation at both Pinewood and Flatiron reservoirs as we generate hydro-electric power at Pole Hill, Flatiron and the Big Thompson power plants. If you are visiting either Flatiron or Pinewood, please keep the fluctuating nature of the reservoirs in mind. In particular, please remember there is no boating, wading, swimming, etc. of any kind allowed in Flatiron. It goes up and down too much and has strong currents.
Those near Lake Estes will see the elevation creep up at Estes slightly. Releases from Olympus Dam to the Big Thompson River have remained around 125 cfs for the past week and are anticipated to stay at that rate for a while, weather depending, of course.
