Continuous Water-Quality Monitoring of Middle Snake River Springs in Support of Threatened and Endangered Snail Species
Two species of aquatic snails, the Banbury Springs limpet ( Idaholanx fresti ) and the Bliss Rapids snail ( Taylorconcha serpenticola ) live in springs along the middle Snake River in south-central Idaho. The U.S. Fish and Wildlife Service has listed these species as Endangered (Banbury Springs limpet) and Threatened (Bliss Rapids snail). Both species need clean, cold spring water to survive.
Idaho's Large River Ambient Monitoring Network
From 1989 to 2009, the U.S. Geological Survey, in cooperation with the Idaho Department of Environmental Quality, monitored trends in water quality and biological integrity at more than 50 USGS streamgage stations on rivers throughout Idaho. In 2018, multiple State and Federal partners restarted a portion of the Large River Ambient Monitoring (LRAM) network.
Automated Sampling for Phosphorus in the Lower Boise River
For decades, the lower Boise River downstream of Lucky Peak Reservoir has been highly enriched with phosphorus. Too much of a good thing, the high concentrations of phosphorus create a cycle of excessive plant growth, decreased oxygen for fish, and even algal blooms.
Assessing the Water Quality of the Lower Boise River and Selected Tributaries
For decades, the lower Boise River downstream of Lucky Peak Reservoir has been highly enriched with phosphorus. Too much of a good thing, the high concentrations of phosphorus create a cycle of excessive plant growth, decreased oxygen for fish, and even algal blooms.
Naval Reactors Facility Groundwater-Quality Monitoring
As part of the Comprehensive Environmental Response Compensation and Liability Act, it is important to evaluate the effect of Naval Reactors Facility (NRF) activities on the water quality of the eastern Snake River Plain aquifer.
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...
Wood River Valley Aquifer System - Water-Quality Assessment
A component of groundwater availability is whether the water quality is suitable for a particular use. Elected officials, water managers, and the general public have raised concerns about whether water quality has been affected in developed and agricultural areas by wastewater disposal, fertilizer application, and animal waste.
