Slide1: Who’s Water is it? Who’s Water Is It?: Who’s Water Is It? The average annual flow of the Arkansas River, as measured at the Wellsville gage is 523,200 acre-feet An acre-foot of water is 325,851 gallons. One cubic foot per second will equal 1.98 acre-feet of water in a 24-hour period.

The Wellsville gage is used to administer the Arkansas River Flow Management Program Arkansas River Flow Management Program: Arkansas River Flow Management Program The highest priority for the flow program is the maintenance of a year-around flow of 250 cfs to protect the fishery. Arkansas River Flow Management Program: Arkansas River Flow Management Program From July 1 thru August 15, flows are augmented to maintain 700 cfs at the Wellsville gage to enhance recreational boating. These flows are dependent on water availability and storage levels in the reservoirs.

In accordance with the Allocation Principles, water is allocated 51% to municipalities and 49% to agriculture. Irrigation belowPueblo Reservoir: Irrigation below Pueblo Reservoir Historically, 75% of Fry-Ark water has been used to supplement irrigation of over 200,000 acres of farmland. Since the drought of 2002, cities have taken their full allocation of Fry-Ark water. Fountain Valley Conduit: Fountain Valley Conduit 45-mile long conduit from Pueblo Reservoir to Colorado Springs Conveys approx. 20,100 acre-feet of water to Colorado Springs, Fountain, Stratmoor Hills, Widefield and Security Exchanges: Exchanges An exchange is an operation where a water user can take water in a stream system out of priority and replace it with a like amount of water at another point on the stream. The exchange may not cause injury to other water rights between the diversion and replacement points or to water rights downstream of the diversion. Exchanges: Exchanges Questions? : Questions?
