The largest increase in groundwater pumping has been in and around the Bureau of Reclamation\u2019s Klamath Irrigation Project, which includes the Tule Lake subbasin in the southern part of the upper Klamath Basin. Agricultural drains on the Klamath Project are an important source of water for downstream irrigators and for the Tule Lake and Lower Klamath Lake National Wildlife Refuges. U.S. Geological Survey regional groundwater-flow model simulations and records of irrigation-return flow pumped from the Tule Lake subbasin into the adjacent Lower Klamath Lake subbasin have indicated that water-level declines from pumping may be causing decreased flow of shallow groundwater to agricultural drains.\u00a0\nTo better define the effect of increased pumping on drain flow and on the water balance of the groundwater system, the annual water volume pumped from drains in three subareas of the Tule Lake subbasin was estimated and a fine-grid, local groundwater model of the Tule Lake subbasin was constructed. Results of the agricultural-drain flow analysis indicate that groundwater discharge to drains has decreased such that flows in 2012 were approximately 32,400 acre-ft less than the 1997\u20132000 average flow. This decrease was concentrated in the northern and southeastern parts of the subbasin, which corresponds with the areas of greatest groundwater pumping. Model simulation results of the Tule Lake subbasin groundwater model indicate that increased supplemental pumping is the dominant stress to the groundwater system in the subbasin. Simulated supplemental pumping and decreased recharge from irrigation between 2000 and 2010 totaled 323,573 acre-ft, 234,800 acre-ft (73 percent) of which was from supplemental pumping. The response of the groundwater system to this change in stress included about 180,500 acre-ft (56 percent) of decreased groundwater discharge to drains and a 126,000 acre-ft (39 percent) reduction in aquifer storage. The remaining 5 percent came from reduced groundwater flow to other model boundaries, including the Lost River, the Tule Lake sumps, and interbasin flow.", "description": "vi, 44 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Pischel, Esther M. epischel@usgs.gov", "givenName": "Esther M.", "familyName": "Pischel", "email": "epischel@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-0393-6993", "url": "https://orcid.org/0000-0002-0393-6993"}, "affiliation": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}]}, {"@type": "Person", "name": "Gannett, Marshall W. mgannett@usgs.gov", "givenName": "Marshall W.", "familyName": "Gannett", "email": "mgannett@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-2498-2427", "url": "https://orcid.org/0000-0003-2498-2427"}, "affiliation": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}]}], "funder": [{"@type": "Organization", "name": "Oregon Water Science Center", "url": "https://www.usgs.gov/centers/oregon-water-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "California", "url": "https://geonames.org/5332921"}, {"@type": "Place", "additionalType": "state", "name": "Oregon", "url": "https://geonames.org/5744337"}, {"@type": "Place", "additionalType": "unknown", "name": "Tule Lake", "url": "https://geonames.org/5318358"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-121.58020019531249, 41.80817277478235], [-121.58020019531249, 42.04317376494972], [-121.3604736328125, 42.04317376494972], [-121.3604736328125, 41.80817277478235], [-121.58020019531249, 41.80817277478235]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 41.92567326986603, "longitude": -121.47033691406251}]}]}
