Watershed Assessment

From headwaters to estuaries, we take a holistic and watershed-wide approach to help set the context and provide key insights for natural and water resource management.

Fish Passage

Providing opportunities for native fish species to access suitable habitat is a key step in restoring aquatic ecosystem function.

River Restoration

From adding wood and boulders to re-creating wetlands, we can help you prioritize, plan, and design your channel and floodplain improvements with an eye towards ecological function.

Environmental Compliance

Our scientific approach ensures targeted, streamlined and defensible impact assessments and mitigation measures.

Hydroelectric Project Licensing

Stillwater staff have supported over 30 FERC projects in study plan development, relicensing, compliance monitoring, and other support throughout the western US.

Flood Protection

Complete levee improvements and maintenance to meet flood control mandates using thoughtful resource protection measures that reduce overall mitigation need.

Urban Streams

Our planners and engineers are accustomed to evaluating, managing, and creating naturally-functioning ecosystems within some of the west coast’s largest urban centers.

Dam Removal

Stillwater scientists specialize in evaluating the impacts of dam removal, specifically the effects on sediment transport, water quality, and fisheries, and how best to model and mitigate.
