Effects of Nutrient Enrichment on Stream Ecosystems (Upper Snake River Basin NAWQA)
Nutrient enrichment can affect the ecological health of a stream. For example, excessive aquatic plant growth caused by increased nutrients can reduce dissolved oxygen necessary for other aquatic life. Topics of particular interest in this study area include:
seasonal patterns among nutrients, flows, algae and plants in streams
rooted aquatic plant vs. algae growth
stream metabolism and nutrient transport processes
field sample technique improvement
Beginning in 2006, we collected and analyzed aquatic chemical, physical, and biological samples to evaluate relationships between nutrients in streams and levels of aquatic plant growth. These analyses helped us to understand the role of nutrient concentrations and eutrophication in agricultural streams nationally and how conditions in the irrigated agricultural settings in the arid west differ from those in the Midwest or Eastern regions of the country.
