From The Pueblo Chieftain (Chris Woodka):
Flows ranging from 5-1,100 cubic feet per second will be released from the new outlet works during the tests. It’s the first time the outlet has been used since construction.
The Arkansas River has been fed by releases from flood gates in the central portion of the dam during construction. River flows have been in the 400 cfs range below the dam recently.
The first test occurred Wednesday afternoon, and more tests are planned Friday and Tuesday, said spokeswoman Kara Lamb.
The Y-shaped outlet is being constructed by Colorado Springs Utilities as part of the Southern Delivery System. It will connect to a 90-inch diameter pipeline leading to a Pueblo West tap and the Juniper Pump Station, which will be constructed near the dam. The other pipeline will serve as the river outlet.
