"The goal of this project is to characterize the vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake."
Management of Upper Klamath Lake depends on adequate knowledge of inputs to the lake of both water and nutrients. Loadings of phosphorus and other nutrients to Upper Klamath Lake lead to dense, harmful algal blooms during the summer and degrade water quality and stress endangered fisheries. In 2002, The Oregon Department of Environmental Quality (ODEQ) established a total maximum daily load (TMDL) management model that targeted a 40 percent reduction in phosphorus loading to Upper Klamath Lake from external sources in the drainage. It is also recognized that flux through the lake’s sediment is a potentially important but as yet uncharacterized source of phosphorus loading to the lake (“internal loading) that may help trigger and sustain algal blooms. In order to manage and restore lake water quality it is necessary to understand the processes that contribute to internal phosphorus loading and their relative magnitudes.
The goal of this project is to characterize the vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake and identify any spatial or temporal variability.

USGS Klamath River Basin Water-Quality Mapper
The Klamath River Basin Water-Quality Mapper allows users to explore and access water-quality data from the Klamath River Basin that were collected by the USGS and the Bureau of Reclamation. This web-based application provides access to hundreds of time series datasets and thousands of discrete sample results.
USGS Data Grapher
This is a data graphing utility that allows the user to build graphs of data from selected USGS stations. Select the station, the type of graph, the parameter(s) to plot, and the starting and ending dates for the graph.

Klamath Basin Studies
In 1992, the USGS began studying possible causes for the change in trophic status of Upper Klamath Lake. Since then research has expanded to include groundwater, geomorphology, streamflow forecasting, and fish ecology.Upper Klamath Basin Groundwater Studies
Since the late 1990s the USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to help evaluate the state of the groundwater system and its response to external stresses, and to develop computer models to provide insights useful for water management. These efforts build on earlier USGS studies in the basin going back to... - Data
