Currently, \nirrigated acreage is estimated routinely for only a few basins in the study area and these acreages are \ncalculated and reported by township range section, quarter, and quarter-quarter.  Satellite imagery from \nthe Landsat Thematic Mapper (TM) platform was used to delineate irrigated acreage for the BARCAS \nstudy area on a field by field basis.  Six hundred and forty-three fields were delineated by interpreting \nsatellite data. The water source, irrigation system, crop type, and field activity were identified and \nverified through field reconnaissance. These data were integrated into the geodatabase and analyzed \nto develop reasonably accurate estimates of irrigated acreage for the 2000, 2002, and 2005 growing \nseasons by hydrographic area and sub-area. Estimated average annual potential evapotranspiration \nand average annual precipitation were incorporated into the geodatabase as ancillary data. Irrigated \nacreage in 2005 totaled nearly 32,000 acres ranging from less than 200 acres in Butte, Cave, Jakes, \nLong, and Tippett Valleys to 9,200 acres in Snake Valley. Cave, Irrigated acreage increased about 20 \npercent from 2000 to 2005, with Snake and White River Valleys experiencing the greatest increases. \nThe source for about 80 percent of irrigation water applied during drier years is ground water pumped \nfrom wells. About 80 percent of irrigation water applied in 2005 was through sprinkler systems, and \nabout 20 percent was through flood systems. Fields planted in alfalfa accounted for about 88 percent \nof the irrigated acreage.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://water.usgs.gov/lookup/getspatial?ds273_DelineatedIrrigatedAcreage_Geodatabase", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.ef4ae96f-9ddf-4f5b-90b9-dfe460b13d4f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_ef4ae96f-9ddf-4f5b-90b9-dfe460b13d4f", "keyword": ["Agriculture", "Butte Valley", "Cave Valley", "Inland waters", "Irrigation", "Jakes Valley", "Lake Valley", "Little Smoky Valley", "Long Valley", "Nevada", "Newark Valley", "Snake Valley", "Southwest United States", "Spring Valley", "Steptoe Valley", "Tippett Valley", "USGS:ef4ae96f-9ddf-4f5b-90b9-dfe460b13d4f", "Utah", "White River Valley", "agriculture", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-116.034926, 37.987253, -113.676000, 40.302025", "theme": ["geospatial"], "title": "Irrigated Acreage Geodatabase Within the Basin and Range Carbonate-Rock Aquifer System, White Pine County, Nevada, and Adjacent Areas in Nevada and Utah"}
