Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

EcoFlows: Understanding Streamflow Dynamics in Small Mountain Streams

The WY-MT WSC is collaborating with the Northern Rocky Mountain Science Center to understand the dynamics of streamflows in small, mountain streams during the course of the year, and to describe the amount of variability associated with those measurments. These findings will assist fisheries biologists who are researching...

National water summary 1987: Hydrologic events and water supply and use

Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...
