In March 1958, the nearby community of Norton, Kansas secured a contract with the U.S. government to receive 1,600 acre-feet of water annually.[9] In 1963, the Kansas state government granted the community a water right to that amount of storage in the reservoir.[6] Norton began to use the reservoir as a municipal water supply in September 1965.[9]
The reservoir is impounded at its northeastern end by Norton Dam.[10][11]Prairie Dog Creek is both the reservoir's primary inflow from the southwest and its outflow to the northeast.[10]
The city of Norton lies 2.5 miles (4.0km) northeast of the reservoir.[8]
Hydrography
The surface area, surface elevation, and water volume of the reservoir fluctuate based on inflow and local climatic conditions.[1] In terms of capacity, the Bureau of Reclamation vertically divides the reservoir into a set of pools based on volume and water level, and it considers the reservoir full when filled to the capacity of its active conservation pool.[1][3] When full, Keith Sebelius Lake has a surface area of 2,181 acres (8.83km2), a surface elevation of 2,304 feet (702m), and a volume of 34,510 acre-feet (42,570,000m3). When filled to maximum capacity, it has a surface area of 6,713 acres (27.17km2), a surface elevation of 2,341 feet (714m), and a volume of 192,027 acre-feet (236,862,000m3).[3][12]
The streambed underlying the reservoir has an elevation of 2,245 feet (684m).[3] Since the reservoir's initial flooding, sedimentation has gradually accumulated on the reservoir bottom thus raising its elevation.[12]
Infrastructure
Norton Dam is a zoned earth-fill embankment dam with rock riprap on its upstream face.[6] It has a structural height of 151 feet (46m) and a length of 6,450 feet (1,970m). At its crest, the dam has an elevation of 2,347 feet (715m).[13] A spillway structure controlled by three radial gates is located at the southeast end of the dam. Outlet works at the northwest end of the dam manage outflow into Prairie Dog Creek and the city of Norton's municipal water supply.[6]
Management
Norton Dam
The U.S. Bureau of Reclamation maintains and operates the reservoir and Norton Dam. The U.S. Army Corps of Engineers provides water regulation procedures for flood control. Downstream canals and structures which use portions of the reservoir's water for irrigation are managed by Almena Irrigation District No. 5.[6] The Kansas Department of Wildlife, Parks and Tourism (KDWP) manages the surface of the reservoir and 6,500 acres (26km2) of land around it as the Norton Wildlife Area.[6][14]
Parks and recreation
The KDWP operates the 1,150-acre (4.7km2)Prairie Dog State Park on the reservoir's north shore.[5] It includes boat ramps, camping facilities, a hiking trail, and a swimming beach.[15]
Keith Sebelius Lake is open for sport fishing year-round.[6] Hunting is permitted on the public land around the reservoir although it is restricted in certain areas.[14]
Points of interest
The KDWP preserves two vintage 19th-century buildings in Prairie Dog State Park: a one-room schoolhouse and the last standing original adobe house in Kansas. The park also hosts a growing prairie dog town.[15]
