Geophysical investigations for groundwater in the lower Klamath Lake basin, Oregon

Since the early 1900's the Klamath Basin, in the western United States, has relied heavily on surface water for irrigation. A large infrastructure of dams, canals and pump stations has been developed to service approximately 1500 farms. In the summer of 2001, with drought conditions and a concern for endangered species, the United States Bureau of Reclamation completely cutoff all irrigation water from Upper Klamath Lake, leaving approximately 1500 farms without water for crops. A flurry of groundwater exploration ensued.
