From The Pueblo Chieftain (Chris Woodka):
What to do with all the water?
The Southeastern Colorado Water Conservancy District tackled the question Thursday by approving additional allocations requested by cities and farms in the Arkansas Valley.
But more than half of additional water brought in by the Fryingpan-Arkansas Project will be carried over to next year and added to next year’s allocations.
In May, the district allocated about 46,000 acre-feet (15 billion gallons), with about one-third going to cities and two-thirds to farms. But continued wet conditions added another 22,500 acre-feet to the amount available for allocation.
A total of 72,000 acrefeet were imported, but some of it goes for other obligations or to account for losses.
Wet conditions and the way water has to be delivered or accounted for cut down on demand for the additional water, Executive Director Jim Broderick explained.
Most cities had plenty of water in storage and not many places to store additional water.
“A lot of people were at their limit and not making request,” Broderick said. “It’s been a wet year and there is no place to put the water. Everything got full.”
The big exception was the Pueblo Board of Water Works, which did not take any water from the first allocation. Pueblo Water took 6,500 acre-feet. All told, cities added 8,200 acre-feet to their supplies.
The large canal companies downstream did not jump at all of the additional water either, because there was no way to store it for when it would be needed. About 2,600 acre-feet were allocated during the second round.
That still leaves about 11,700 acre-feet that was brought over from the Fryingpan River basin through the Boustead Tunnel into Turquoise Lake for later distribution in the Arkansas River basin.
“It will be applied to the first allocation next year,” Broderick said. “My guess is that a lot of the water is going to be available to agriculture.”
That could create a problem even with average moisture next spring, raising the possibility that water stored in excess capacity, or if-and-when accounts, could spill.
About 55,000 acre-feet of if-and-when water is stored in Lake Pueblo now, about one-quarter of the water in the reservoir.
Some winter water could also spill, if the amount exceeds 70,000 acre-feet. About 24,000 acre-feet are now in storage. However, winter water could be stored downstream as well.
Turquoise and Twin Lakes are nearly storing at capacity. Lake Pueblo is at 80 percent of capacity, but 145 percent of average for this time of year, according to Roy Vaughan, manager of the Fry-Ark Project for the Bureau of Reclamation.
If water conditions are typical, 26,000 acre-feet could spill next spring, but it is too soon to make an accurate prediction, Vaughan said. But he said most forecasts are calling for at least 100 percent of snowpack.
“Part of the question is are we bringing water in and using it that year, or are we storing it?” Broderick said. “For the past few years, we have been using other water and storing (Fry-Ark) water.”
