You are invited to learn a new online tool for exploring streamflow in the Skagit River watershed. The tool provides historical and future streamflows based on hydrologic modeling by University of Washington (UW). The visualization and streamflow data can be used in long-term planning as well as in designs for long-lived infrastructure and resource projects. This training includes slides for a presentation and interactive run exercises using the visualization tool and explore how to use the tool to discover interesting patterns based on CMIP5 climate changes.

As the climate warms, people want information on what to consider as they plan for potential changes in streamflows. The following visualizations show a large set of outputs from a modeling study conducted by researchers at the University of Washington Civil and Environmental Engineering Department and supported by several organizations with a common interest in understanding a potential range of future conditions (Seattle City Light, Swinomish Indian Tribal Community, and the Sauk-Suiattle Indian Tribe in partnership with the Skagit Climate Science Consortium). The study is available at: The study modeled projected changes in streamflows at 20 locations in the Skagit River Watershed.

Specific locations modeled include: Red Cabin Creek, Finney Creek, Jackman Creek, Illabot Creek, Cascade River, Jordan Creek, Bacon Creek, Marblemount to Newhalem, Gorge, Diablo,Thunder Creek, Ross, Sauk River near Sauk, Big Creek, Sauk River at Darrington, Sauk River above Clear Creek, Sauk River above White Chuck, White Chuck, North Fork Sauk River, South Fork Sauk River,

Visualizations include Monthly Averages and Extremes within multiple dashboard page viewers with embedded maps, charts, and figures, with a tab on Definitions & Documentation used in the visualizations also provided.
