Bathymetric Mapping of the Kootenai River

The Kootenai River white sturgeon (Acipenser transmontanus) and other native fish species are culturally important to the Kootenai Tribe of Idaho, but their habitat and recruitment have been affected by anthropogenic changes to the river. The Tribe has undertaken a large-scale restoration project and needs objective...

Modeling the Hydraulic and Water-Quality Habitat Suitability for Macrophytes in the Middle Snake River, South-Central Idaho

Rooted aquatic plants (macrophytes) are essential components of freshwater ecosystems. Macrophyte beds provide shelter for fish and other aquatic life. Their leaves and stems also provide algae with surfaces to colonize, which, in turn, drives the aquatic food webs and dissolved oxygen cycles. However, too much of a good thing can create problems. When growth conditions are favorable,...

Wood River Valley Aquatic Biology and Habitat Assessment

Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...

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...

Panther Creek: Evaluating Recovery of a Mining-Damaged Stream Ecosystem

Historically, Idaho has been home to many productive underground and open-pit mining operations. These activities have also produced water quality problems in some areas. One such example is the Blackbird Mine in central Idaho. Following mining operations from the 1940s through the 1960s, Panther Creek and its tributaries were severely damaged by runoff from the Blackbird Mine. Water-quality...
