Status: Completed

Nitrate in GW, Lower Umatilla Basin, OR

Stretching from Pendleton, Oreg., to the Columbia River, the Lower Umatilla Basin covers 550 square miles. Concentrations of nitrate in the basin's ground water frequently exceed national drinking-water standards. The basin's complex ground-water system is exposed to five human-related sources of nitrate: septic tanks, feedlots, explosives, fertilizer, and land applications of food waste....

Elwha River

The formerly free-flowing Elwha River was famous for the diversity and size of its salmon runs. After the construction of the Elwha Dam (1912) and the Glines Canyon Dam (1927), fish lost access to more than 70 miles of mainstem river and tributary habitat. As a result, all 10 runs of native Elwha salmon and sea-going trout declined sharply. Restoration of the Elwha River ecosystem will be...

Nooksack River Ground-Water Bacteria

The lower Nooksack River Basin is located in Whatcom County, in the northwestern part of Washington. Within areas of the basin, the ground-water aquifer is shallow. Knowledge of how the surface water and the aquifer interact, and how this interaction affects the transport of bacteria and nitrates from agricultural fields to the ground-water system, is important to residents of the basin. This...

Multispectral imaging, Puyallup River

In the past, levees have been built along the river banks of the Puyallup River to prevent floodwater from damaging roads, buildings, farms, and other areas in the floodplain. Because levees can worsen flooding by creating backwater effects or reducing floodplain storage, Pierce County is planning to remove current levees and build new ones further away from the river channels.

Water Resources of the Tulalip Indian Reservation

Future increases in population and development of the Tulalip Indian Reservation and neighboring areas would lead to increased pumping of ground water both on and off the Reservation. Increased pumpage in coastal and inland wells may decrease baseflows of streams and could affect fish-rearing operations in the Tulalip Creek watershed.

Satus Creek

After irrigating croplands, water returned to creeks and rivers in the Yakima River Basin can contribute compounds and materials that affect the quality of habitat. On lands of the Yakama Nation, Satus Creek receives water from the North Drain that brings with it sediment, nutrients, bacteria, and pesticides, degrading the aquatic habitat and posing a barrier for endangered fish in the creek...

Urban Pesticide

Salmon and other aquatic life in the Puget Sound Basin need a healthy habitat to survive and to recover from historical declines, both in urban and agricultural settings. Yet, USGS studies in 1997 and 1998 found that more pesticides were found in urban streams than in agricultural streams, and that 9 out of 10 samples from urban streams had concentrations of insecticides exceeding levels...

Continuous Gas Monitoring Tracks Volcanic Activity at Mount St. Helens

Volcano gas geochemistry has been around for a long time. Scientists can make gas measurements using very large, very expensive Correlation Spectrometers or collect samples in the field and bring them back for analysis in the lab. But it’s possible we’re missing out on a lot of information because our monitoring capabilities don’t include continuous observation.
