Integrating Stormwater Drainage into USGS StreamStats Application for the Duwamish and Lower Green River
The U.S. Geological Survey (USGS) is developing a Duwamish and Lower Green River Storm Drain StreamStats application to help communities and decision-makers address stormwater challenges in the Duwamish and lower Green River watershed.
This free, publicly accessible tool will allow users to delineate stormwater drainage areas and calculate basin characteristics, supporting climate resiliency and improved water quality.
Project Goals
- Create the Duwamish and Lower Green River StreamStats application for stormwater analysis.
- Engage communities and partners through outreach and training.
- Publish data and resources to support local planning and decision-making.
What the App will Do
The U.S. Geological Survey’s (USGS) StreamStats web application allows you to delineate drainage areas and calculate basin characteristics.
This project will enhance StreamStats for areas within the Duwamish and lower Green River watershed. It will compile high-resolution elevation data and existing municipal data on stormwater infrastructure systems and integrate these datasets into a new tool within StreamStats. Critically, the application will allow you to access information for any location within the watershed, not just for pre-defined watersheds.
The tool will allow users to:
- View the network of stormwater inlets, pipes, ditches & streams.
- Delineate drainage areas derived from high-resolution elevation data and stormwater infrastructure.
- Compute additional high-resolution basin characteristics, such as impervious cover, tree cover, traffic counts, population density, precipitation, and slope.
These functions are already available for three select areas (St. Louis, Missouri; the Mystic River basin in Boston, Massachusetts; and Washington, District of Columbia). We are expanding the functionality to the Duwamish and lower Green River watershed, and tailoring the data available to meet local needs.
Why This Matters
The Duwamish and lower Green River watershed is highly urbanized, with extensive impervious surfaces and complex stormwater infrastructure. Residents face flooding during heavy rainfall, and the Duwamish and lower Green Rivers provide critical habitat for salmon and other species.
Stormwater infrastructure, such as pipes and drains, in addition to topography, determines how water flows through cities. USGS is incorporating stormwater infrastructure into the StreamStats application to better represent how water moves through the Duwamish and lower Green River watershed.
By integrating high-resolution elevation and stormwater infrastructure data, this project will support efforts to:
- Assess water quantity and inform water-resource planning.
- Reduce flooding impacts on vulnerable communities.
- Improve water quality in the Duwamish and lower Green Rivers and tributaries.
- Support stormwater engineering and design.
How Partners Can Engage
We invite municipalities, Tribes, community organizations and residents, and local decision-makers to participate in shaping this tool. Your input will ensure the application meets real-world needs. We plan to host kickoff meetings, listening sessions, and training webinars. We will post engagement opportunities here, in addition to reaching out directly to partners.
