Total dissolved gas and water temperature in the lower Columbia river, Oregon and Washington, 2004: Quality-assurance data and comparison to water-quality standards
Dwight Q. Tanner, Heather M. Bragg, Matthew Johnston
2004, Scientific Investigations Report 2004-5249
Significant Findings When water is released through the spillways of dams, air is entrained in the water, increasing the downstream concentration of total dissolved gas. Excess dissolved-gas concentrations can have adverse effects on freshwater aquatic life. The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE),...
Chloroform in the hydrologic system--sources, transport, fate, occurrence, and effects on human health and aquatic organisms
Tamara Ivahnenko, Jack E. Barbash
2004, Scientific Investigations Report 2004-5137
Chloroform is one of the volatile organic compounds (VOCs) detected most frequently in both ground and surface water. Because it is also one of the four trihalomethanes (THMs) produced in the highest concentrations during the chlorination of drinking water and wastewater, the frequent detection of this compound in ground and...

Various water managers in Montana need comprehensive, current, and detailed water-use data to quantify current stresses and estimate...
Determination of channel-morphology characteristics, bankfull discharge, and various design-peak discharges in western Montana
Sean M. Lawlor
2004, Scientific Investigations Report 2004-5263
Stream-restoration projects using natural stream designs typically are based on channel configurations that can accommodate a wide range of streamflow and sediment-transport conditions without excessive erosion or deposition. Bankfull discharge is an index of streamflow considered to be closely related to channel shape, size, and slope (channel morphology). Because of...
