Reconnaissance Investigation of Water Quality, Bottom Sediment, and BiotaAssociated with Irrigation Drainage in the Klamath Basin, California and Oregon, 1988-89

摘要

The report describes results of a reconnaissance-level field investigation of thequality of irrigation drain water and the effects of its use on federally managed wildlife refuges in the Klamath Basin, California and Oregon. The investigation was designed to indicate the magnitude and extent of any water-quality problems that could threaten wildlife and human health. The investigation also was designed to use similar sampling strategies and sampling media as was used in all Department of the Interior reconnaissance studies throughout the Western United States, thus providing a consistency that would allow comparison between studies. Information provided by the investigation will be used by the DOI Task Group on Irrigation Drainage to evaluate the need for more detailed study. Samples of water, bottom sediment, and biological tissues were collected in 1988 at various locations on or near the refuges and analyzed for selected chemical constituents.
