Doing so requires an ongoing understanding of streamflow characteristics of the rivers and streams in South Carolina. A...
Statistical analysis of the water-quality monitoring program, Upper Klamath Lake, Oregon, and optimization of the program for 2013 and beyond
Sara L. Caldwell Eldridge, Susan A. Wherry, Tamara M. Wood
2014, Open-File Report 2014-1009
Upper Klamath Lake in south-central Oregon has become increasingly eutrophic over the past century and now experiences seasonal cyanobacteria-dominated and potentially toxic phytoplankton blooms. Growth and decline of these blooms create poor water-quality conditions that can be detrimental to fish, including two resident endangered sucker species. Upper Klamath Lake is...
