Lower Blue bumps up today--stay away!
As I had mentioned earlier this spring, we are doing Coordinated Reservoir Operations this year. The "CROS" program is part of the Upper Colorado River Basin Endangered Fish Recovery Program. In years there is above average snowpack, like we had this year, reservoirs in the upper Colorado River basin work together to coordinate and time releases so that they augment the natural river peak of the Colorado River between Cameo and Grand Junction. That stretch of river is critical to the recovery of the four endangered fish of the Colorado River.
What this means for you all is that Green Mountain, a participating reservoir, will start increasing releases this afternoon at 3:00. We are currently releasing 110 cfs. At 3 p.m., we will bump up to 225. But we're not done. We have to get to 1000 cfs by tomorrow evening, so, there will be subsequent releases of about 200 cfs, each, today and tomorrow. Our anticipated release schedule looks like this:
Date Time From To
5/19 1500 110 cfs 225 cfs
5/19 2000 225 cfs 400 cfs
5/20 0600 400 cfs 600 cfs
5/20 1300 600 cfs 750 cfs
5/20 2000 750 cfs 1000 cfs
Because releases will go up incrementally, we are asking that boaters and fisherfolk please stay out of the river until our ramp up is complete. It looks like by Saturday evening, we will be done, leaving Sunday free of ramping rates on the Lower Blue. By then, the cfs will be around 1000.
I'm not sure how long we'll be running this rate out of Green Mountain. We had originally projected about two weeks, but with this hot weather and resulting rate of run off, we might not last that long. I'll keep you all posted and, as always, please feel free to give me a holler. I'm in all day today and on cell phone over the weekend at (970) 215-9545.
