Hydrology and Water Chemistry of the Benton Lake Basin with Emphasis on the Fateof Dissolved Solids at Benton Lake National Wildlife Refuge, West-Central Montana

摘要

The purpose of this report is to present the results of a hydrogeochemical studyof the Benton Lake basin. Specific objectives of this report are to describe: The hydrology and water chemistry of ground water, saline seeps, and streamflow in the Benton Lake basin; The hydrology and water chemistry of Benton Lake, including the loading of dissolved solids and selenium to Benton Lake; The fate of dissolved solids within Benton Lake; and The implications of dissolved-solids chemistry on management of water-bird habitat at Benton Lake NWR. The report describes the collection anad analysis of physical and chemical data from the Benton Lake basin.
