Coal Transport

The Issue: Federal and state natural resource managers and Tribes are concerned with the environmental impacts from unintentional release of coal dust from train cars during transport through the Northwest. Proposed new coal export terminals in Washington and Oregon would substantially increase rail traffic through the Northwest and the release of coal dust to the environment...

Quinault Groundwater

The Issue: Located on the north coast of Washington within the Queets-Quinault Watershed, the Quinault Indian Nation's coastal communities rely on groundwater as their sole source of drinking water. Climate change can directly affect groundwater throughout the watershed, particularly worrisome in vulnerable coastal aquifers. The Quinault Indian Nation will be collecting...

Riparian Ecology

Riparian ecologists in the AS Branch study interactions among flow, channel change, and vegetation along rivers across the western United States and worldwide. Our work focuses on issues relevant to the management of water and public lands, including dam operation, climate change, invasive species, and ecological restoration. Investigations take place on a range of scales. For example,...

Riparian Vegetation Response to Dam Removal

Dam removal is an approach to river restoration that is becoming increasingly common. In most cases, dam removal is driven by considerations other than river restoration like dam safety, but how dam removal affects aquatic and riparian systems is of great interest in many dam removals. My work in this area has had two areas of focus thus far: 1) studies of vegetation and geomorphic change...

Streamflow-fluvial Geomorphology-riparian Vegetation Interactions

The foundation for applying science to river and riparian restoration contexts lies in a basic understanding of the factors that drive riparian vegetation dynamics. Much of our research is focused on clarifying relationships between streamflow, fluvial geomorphology, and riparian vegetation, including various feedbacks.

Western Drought Resilience Assessment

We collected streamflow, water temperature, and other data from more than 2,500 gaging stations on rivers and streams across California, Idaho, Nevada, Oregon, Utah, and Washington to document the severity of the 2015 drought. We are using the data collected to assess how warmer winter temperatures, reduced mountain snowpack, and a shift in precipitation from snow to rain may affect future...

Mason County

The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in Mason County, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable...

Water Management Studies

As the need for incorporating biological objectives into water management decisions has grown, so has the need for methods and metrics to incorporate predictions of relevant biological responses into an increasingly complex decision environment that attempts to balance multiple uses.

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats. Without this information, NAWMP population, habitat, and people objectives may not reflect stakeholder and societal values; and management...

Evaluating the reintroduction potential and limiting factors associated with anadromous fish reintroductions in the Upper Lewis River, WA

Hydropower facilities on the Lewis River, WA eliminated historic runs of anadromous species to the headwaters of the Lewis River. As anadromous reintroductions are considered and implemented, there remains considerable uncertainty in the viability of reintroductions in reservoir and tributary systems where large populations of non-native species persist and where spawning and rearing habitat...
