Nutrient loads in the Lost River and Klamath River Basins, south-central Oregon and northern California, March 2012–March 2015
The U.S. Geological Survey and Bureau of Reclamation collected water-quality data from March 2012 to March 2015 at locations in the Lost River and Klamath River Basins, Oregon, in an effort to characterize water quality and compute a nutrient budget for the Bureau of Reclamation Klamath Reclamation Project. The study described in this report...Schenk, Liam N.; Stewart, Marc A.; Caldwell Eldridge, Sara L.
Klamath River Basin water-quality data
The Klamath River Basin stretches from the mountains and inland basins of south-central Oregon and northern California to the Pacific Ocean, spanning multiple climatic regions and encompassing a variety of ecosystems. Water quantity and water quality are important topics in the basin, because water is a critical resource for farming and municipal...Sobieszczyk, Steven; Smith, Cassandra D.; Rounds, Stewart A.; Orzol, Leonard L.
