Christopher Konrad is a research hydrologist with U.S. Geological Survey in Tacoma, Washington.
His research integrates data collected from ground-based observations and networks, aircraft, and satellites with quantitative analysis and model development to address key scientific questions for environmental management. Dr. Konrad’s expertise spans many topics in the field of hydrology: streamflow, floods, and drought; hydraulics and fluvial sediment transport; groundwater and surface water interactions; and the effects of water management and land use on river ecosystems. Dr. Konrad served as the River Science Coordinator for The Nature Conservancy and USGS from 2007 to 2011 working on the development and evaluation of ecological flow requirements for rivers. He earned a BS in Biological Sciences from Stanford University and MS and PhD in Civil and Environmental Engineering from the University of Washington.

Analysis of USGS Surface Water Monitoring Networks
The issue: National interests in water information are important but challenging to incorporate into planning and operation of a monitoring network driven by local information needs. These interests include an understanding of the spatial variability in water availability across the United States, anthro-physical factors including climate and land use that affect water availability, and federal...
USGS science supporting the Elwha River Restoration Project
The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington.
River Corridor hot spots for biogeochemical processing: a continental scale synthesis
Rivers are the veins of the landscape, providing environmental benefits that are disproportionately high relative to their aerial extent; shedding flood waters, hosting aquatic ecosystems, transporting solutes and energy-rich materials, and storing and transforming pollutants into less harmful forms. From uplands to the coasts, rivers facilitate key biogeochemical reactions that cumulatively influ
Cedar River Peak Flow Management
The Cedar River watershed provides two-thirds of the water supply for the greater Seattle metropolitan region, in addition to being home to numerous federally listed salmon species. The City of Seattle, through Seattle Public Utilities (SPU), works closely with the Cedar River Instream Flow Commission (IFC) to adaptively manage flows on the Cedar River. Seattle operates its water management...
NWIFC Water Assessment
Water resources are essential to Native American Tribes in western Washington for instream and out-of-stream uses. As the demand for water across the region increases, western Washington Tribes need critical information about water availability, water use, and ecological needs for water in order to manage their resources. To assess tribal water resources comprehensively in western Washington, the...
Green River Geomorphic Responses
In the Pacific Northwest, water, sediment, and vegetation primarily determine the form of large river channels and shape their ecosystems. Dams on rivers affect all of these elements, with consequences for habitats and aquatic species. Understanding how water, sediment, and vegetation interact in habitats is key to managing rivers. In the case of the middle Green River in King County, Washington...
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...
GW/SW Interactions
Knowing the interactions of ground water and river water can help reduce the fluctuation of water supplies in alluvial (sediment-deposit) river basins. To develop general principles of these interactions in order to identify and analyze them, the USGS is reviewing the results of the numerous studies of these interactions in Pacific Northwest basins. The review will describe common geologic aspects...
Methow River Basin
The Methow River Basin, located in North Central Washington in Okanogan County, is well known for its natural beauty, wildlife, outdoor recreation, and rural lifestyle. The Methow River and its tributaries are home to upper Columbia summer steelhead and spring Chinook salmon, which are both listed as endangered under the Endangered Species Act (ESA), and bull trout, which is listed as threatened...
Hydrologic Urban Indicators
Storm water, the rainfall that runs off urban surfaces such as rooftops, pavement, and lawns, can affect streams in a number of ways. As urban development increases, storm water can run quickly into streams, increasing the volume and peak flows and reducing summer flows. Sediment and other contaminants can also be carried into the streams. The Washington Department of Ecology (WDOE), the state...
