Title: 1997 other irrigated areas (non center pivot) delineated for the Cooperative Hydrology Study in the Central Platte River Basin
Publication Information:
Publisher: CALMIT
Description:
Abstract:
Irrigation information was obtained from the Nebraska Department of Natural Resources, Public Power Districts, and Natural Resource Districts. All irrigation data were checked for accuracy by Nebraska Natural Resource Districts. This data was collected for use in the Platte River Cooperative Hydrology Study.
Purpose:
The irrigated areas will be a factor when running the hydrologic model on 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, environmental impact assessments, and other natural resource management activities.

Process Description:
Irrigation data were collected from a variety of sources. 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. All of the above mentioned sources were appended into one file and printed on maps divided by Natural Resource Districts. These maps were sent out to each Natural Resource District within the study area and checked for accuracy. Maps were checked using existing knowledge of 1997 irrigated areas and Farm Service Agency reporting records from 1997. When these maps were returned the original vector files were edited and all files were merged into one map for use in the Platte River Cooperative Hydrology Study. These irrigated acres will be a factor when running the hydrologic model on the study area.
