Effect of Climate Change on the Hydrology of the Chehalis Basin
(2016-07-08)Recent flooding in the Chehalis basin has led managers, residents, and others to begin evaluating options for managing flood risk in the future (e.g., Ruckleshaus Center 2012). Climate change is expected to both increase ... -
In the Hot Seat: Saving Lives from Extreme Heat in Washington state
(University of Washington Climate Impacts Group, 2023-06-22)Extremely hot weather is more than just uncomfortable — it can be dangerous and even deadly. In 2021, more than 400 people in Washington died from direct and indirect heat-related causes during a week-long extreme heat ... -
Biophysical Climate Risks and Economic Impacts for Washington State
(University of Washington Climate Impacts Group, 2022-12)The Washington State 2021-23 Operating Budget ESSB 5092 Sec 606(23)) funded the University of Washington Climate Impacts Group (CIG) to “provide an updated climate risk assessment designed to inform future updates to the ... -
Integrating Climate Resilience into Washington State Water System Planning
(University of Washington Climate Impacts Group, 2022-10-13)Through a systematic review of existing water system plans and case study analysis, we explored if and how Washington state’s water system planning process could be a mechanism for climate resilience planning among small ... -

Preparing Washington Department of Fish and Wildlife for a Changing Climate: Assessing Risks and Opportunities for Action
(University of Washington Climate Impacts Group, 2021-06)The Washington Department of Fish and Wildlife (WDFW) recognizes that climate change poses challenges to fulfilling its mission to "preserve, protect and perpetuate fish, wildlife, and ecosystems while providing sustainable ... -
New Culvert Projections for Washington State: Improved Modeling, Probabilistic Projections, and an Updated Web Tool
(University of Washington Climate Impacts Group, 2021-09)This report marks the third phase in a multi-phase project. We developed new streamflow projections, using new dynamically downscaled projections, which are expected to better capture changes in climate at the local level ... -
Bias-Corrected and Dynamically-Downscaled Hourly Temperature Projections for Sea-Tac
(University of Washington Climate Impacts Group, 2021-12)Load forecasting requires hourly temperature estimates in order to better estimate energy demand. This memo describes the bias-correction approach used to develop new dynamically-downscaled projections of historical and ... -
Technical Memo: Projected Changes in Climate Extremes Affecting Seattle City Light
(University of Washington Climate Impacts Group, 2022-01)Changes in extreme weather metrics related to heat, high winds, and lightning may have implications for Seattle City Light operations, planning, and standards. This memo describes an updated assessment of changes in extreme ... -
Projecting Future High Flows on King County Rivers: Phase 2 Results
(2022-05-08)CIG scientists developed estimates of future flooding on the Green, Snoqualmie, and South Fork Skykomish rivers. The aim of this study is to provide King County decision makers with relevant, specific data that will allow ... -
Projected Changes in Streamflow and Water Temperature in Chico Creek, Kitsap County
(2022-05-08)The purpose of this study was to provide projections of future streamflows and water temperatures for use in assessing the impacts of climate change on salmonids in the Chico Creek Watershed. This information is intended ... -
Climate Change & Flooding in Snohomish County: New Dynamically-Downscaled Hydrologic Model Projections
(2022-05-08)We produced new projections of future streamflow, with a particular emphasis on flooding, for the Snohomish and Stillaguamish Rivers. Our results show that peak flows will increase in the future, with increases ranging ... -
