Wichita’s post- World War II population growth, coupled with the USBR’s desire to add public water supply to their traditional irrigation development Doug Helmke mission, brought the Water Rights, city and the USBR Source Water Specialist together to discuss their mutual goals in 1949. Their conversation led to the construction of a dam, reservoir, pumping plant and pipeline. Water from Cheney Reservoir was delivered to Wichita 16 years later in 1965. The site of Cheney Dam was chosen primarily because of Because of Cheney Lake’s elevated location and flat topography, lake winds are allowed to economics. The valley of the North blow unimpeded across the lake.

To better understand and odor are neither easy nor cheap, give its support if the increase in the cause of the taste and odor so the best way to fix the problem is water use by Wichita would only cause a similar increase in pollution of the Arkansas River. Wichita, working with the Kansas State Board of Health, identified the pollution problems and the abatement programs that would address the problems. The Board of Health recommended to U.S. Public Health that federal aid be conditioned to Wichita’s adoption of the abatement programs. This recommendation was accepted. Environmental stewardship has been an important part of this project from the beginning. In the early years, Cheney Reservoir was helpful in meeting Wichita’s peak water demands. Wichita started relying on Cheney water to a much greater extent in the 1980s to meet increasing water demand.
