In 1990, the USGS began assessing water-quality in the Tualatin River. Almost 30 years later, we are still monitoring conditions in the basin.
The Klamath River from Link River to Keno Dam experiences poor water-quality conditions on a seasonal basis, creating inhospitable conditions for fish and other aquatic organisms. These problems led the Oregon Department of Environmental Quality to prepare a Total Maximum Daily Load (TMDL) plan to bring the river into compliance with water-quality standards. This study uses a hydrodynamic and...
Beavers and their dams are common sights along creeks in the Tualatin River basin. Beaver help create diverse habitats for many other animals, including birds, fish, and amphibians. The USGS studying the affect beaver activity has on the amount and quality of water in local streams, so that agencies in the basin can make strategic management and habitat restoration decisions based on science...
A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...
Although sparsely populated, this area in southeastern Oregon, northeastern California, northwestern Nevada, and southeastern Idaho has high geothermal heat flow that may be used to generate large amounts of electricity.
Fish, wildlife, and human populations along the lower Columbia River are exposed to an ever-growing variety of contaminants as a result of increasing urbanization, industrialization, and agricultural development.
The Camas National Wildlife Refugeprovides essential resting, feeding, and nesting habitat for waterfowl including migratory birds. A variety of other animals, large and small, are found there, too. Since the refuge was established in 1937, the U.S. Fish and Wildlife Service (USFWS) has been responsible for managing this vital resource.
Traditionally, Camas Creek and groundwater inflow...
The Arizona Water Use program collects and estimates annual water withdrawals for the categories of irrigation, municipal, mining, thermoelectric-power, and drainage uses. The data for these categories are compiled for the Arizona Department of Water Resources groundwater basins outside of Active Management Areas.
