From the Parker Chronicle (Chris Michlewicz):
The Parker Water and Sanitation District is taking advantage of the wet weather by using its diversion dam on Cherry Creek near Stroh Road. In the last two weeks, it has helped redirect 240 acre-feet of rainwater into Rueter-Hess. That’s 78,204,342 gallons, courtesy of Mother Nature. It’s among the few upsides to the soaking rains that have resulted in historic floods, displacing thousands in the north metro area, decimating roads and homes and taking eight lives along the way…
The PWSD, for the first time this year, raised its diversion structure and pulled off as much as 10,000 gallons per minute during the peak of the first day of storms. Then, just as the weekend was approaching, Cherry Creek was “called out” — in other words, those with downstream water rights declared their privileges to the flows, said Ron Redd, district manager for the PWSD. “We were pulling quite a bit off for a while,” he said. “When they put the call out, it was frustrating with all of that flooding.”
The district worked with a local water commissioner, who grants requests from water rights owners, and was able to lift the restrictions the following day. “We’ve been pumping ever since then,” Redd said.
Some of the rainwater has entered Rueter-Hess through Newlin Gulch, the drainage channel into which the reservoir was built. But much of the work has been done with the diversion dam, which was finished in 2006. It has gotten little use in recent years because of the low water level in Cherry Creek; the PWSD, however, captures alluvial flows from the creek.
The reservoir is a tool for the district to store excess flows, but if there is a call out on the river, the district must release that water, as it did last summer after heavy rains deluged northern Castle Rock, Franktown and areas south of Parker.
