Description:
Abstract:
This data was collected for use in the Cooperative Hydrology Study in the Central Platte River Basin (COHYST).  Irrigation information (non center pivot) was obtained from the Nebraska Department of Natural Resources, Public Power Districts, and Natural Resource Districts.
Purpose:
Identifying irrigated areas within the Central Platte River Basin provides important information necessary to supplement the hydrologic modeling in the study area.  Irrigation data serve a variety of purposes, from water resources planning to land use planning.  This data could also be used for watershed analysis and other natural resource management activities.

Process_Step:
Process_Description:
Irrigation data were collected from a variety of sources.  The 1997 other irrigation layer previously developed by CALMIT was updated using 2001 Farm Service Reporting records. 1997 irrigated acres were collected from Pathfinder Irrigation District.  Pathfinder Irrigation District keeps DXF files of all of their irrigated acres. The original section sized Pathfinder Irrigation District DXF files were brought into ArcInfo, edited, attributed, and appended to create one larger area map for use in the Platte River Cooperative Hydrology Study.  Irrigation maps were also obtained from the Nebraska Department of Natural Resources. These paper maps identifying surface water irrigation rights were digitized using ArcInfo.  The canal project maps include; Castle Rock, Steamboat, Chimney Rock, Empire, Midland-Overland, Graf Canal, Keith-Lincoln, North Platte Canal (Platte Valley I.D.), Paxton-Hershey, Birdwood, Suburban, Cody-Dillon, Western Canal, Thirty Mile Canal, Six Mile Canal, Cozad Canal, and Orchard-Alfalfa Canal. These maps were individually digitized and then merged into one map.  Irrigation data was also obtained from the Central Nebraska Public Power and Irrigation District. The Central Nebraska Public Power and Irrigation District keeps all of their irrigated acres as DXF files.  The original section-sized DXF files were imported into ArcInfo, edited, attributed, and appended to create one larger area map.  Irrigated areas identified on the Nebraska Wyoming border was provided the Wyoming Water Resources Center.  Irrigated areas identified on the Colorado Nebraska border were interpreted using irrigation well data provided by the Colorado Division of Water Resources. This layer was checked for accuracy using  2001 Farm Service Agency reporting records,  registered irrigation well data, 1993 and 1999 digital orthophotography, Landsat 7 satellite imagery and existing knowledge of 2001 irrigated areas provided by Nebraska Natural Resource Districts and the Nebraska Department of Natural Resources. These irrigated acres will be a factor when running the hydrologic model on the study area.
