One of the goals of the Clackamas River Water Providers is to better understand local impacts of climate change on water quality and quantity in the region. It is also to identify climate mitigation and adaption strategies that will help ensure a more resilient watershed and drinking water source for CRWP members.
Clackamas Watershed Resiliency Project
In 2018 the CRWP worked with Portland State University faculty and graduate students and the Institute of Sustainable Solutions (ISS) on a multi-year project aimed to provide water resource stakeholders in the Clackamas River watershed with guidance for managing resilience in the face of climate change. Phase I of this project was to establish a baseline of historical trends in the Clackamas River watershed relevant to climate change and identify issues pertinent to stakeholders in the context of climate change (e.g., diminished summer water supply, water quality degradation resulting from urban development and intense rainfall, etc.). Phase II of this project sought to continue that research with two objectives: (1) Applied Climate Science, (2) Climate Adaptation Planning. The goal of the Clackamas Watershed Resilience project was to help the CRWP understand local impacts of climate change on water quality and quantity in the region; and develop strategies to sustain a healthy, reliable water source.

ODFW Beaver State Podcast
Episode 71: Water Part I – The Clackamas Watershed (October 2021)
Oregon’s rivers, streams, and aquifers support a wide range of benefits for both humans and the environment—sources of water for drinking, agriculture, recreation, and essential habitat for fish and wildlife. A clean and reliable source of water is critical for meeting Oregonian’s basic needs and for supporting Oregon’s economy, but it all hangs under the shadow of climate change. In this episode, we talk to ODFW’s Ben Walczak, Clackamas River Water Provider’s Kim Swan and PGE’s Nick Ackerman about a partnership to tackle the impacts of drought.
