Biological and Human Dimension Components of Water Quality Assessment Measured on a Watershed Scale in the Pacific Northwest Grant uri icon



  • The state of Idaho is under court order to clean-up over 600 stream segments in the state that currently do not meet designated beneficial uses due to one or more of the following pollutants: sediment, nutrients, flow alteration, high temperature, bacteria, lack of dissolved oxygen and/or heavy metals. Science alone can not solve water quality problems, rather the human dimension is important in the implementation of programs that improve water resources within a watershed. This project will use macroinvertebrates as indicators of water quality within watersheds. This technique will allow us to measure water quality improvements following BMP implementation within stream segments that do not meet designated beneficial uses. This project will also assess public attitudes, aptitudes and changes made to enhance water quality within watersheds.
