Lower Blue to jump back up
Even though we are looking at good snowpack, the cooler weather has not produced as large flows into the Colorado River basin as originally anticipated. As a result, the critical habitat for the endangered fish in the Colorado River upstream of Grand Junction will not have the targeted cfs flow necessary for the fish.
That means the Coordinated Reservoir Operations program for the Upper Colorado River Endangered Fish Recovery Program is ON.
Green Mountain will be bumping up from the 800 cfs it was earlier today (Wednesday, June 4) to about 1200 cfs by tomorrow (Thursday, June 5) evening. We will bump up in 100 cfs increments. The first two increases were today, taking us to 1000 cfs in the Lower Blue by 8 p.m. tonight. The next two increases are for tomorrow. The first at 7 am, the second at 7 pm. About 1200 cfs should be in the Lower Blue through the weekend and possibly longer.
The decision to run CROS came about this morning during a weekly conference call between reservoir operators and the State Engineer's Office (Colorado Division of Water Resources). Operators were responding to a quick decline in river volume due to the cooling temperatures. We will have a more formal announcement out tomorrow.
Please feel free to call or e-mail if you have questions or concerns. I am in all day Thursday and Friday.
