The Heat Is On: What Hotter Summers Mean For Streams and People

The illustrated graphic poster, published in 2025, explores the important relationship between air and water temperature in the North Clackamas Watersheds and why keeping streams cool is essential for healthy ecosystems.

Authored by Dr. Leslie King and brought to life through the artwork of Alexander Ryan-Tanner, the poster combines science and visual storytelling to explain how warming temperatures influence watershed health, aquatic habitat, and climate resilience. You can explore more of Alexander Ryan-Tanner’s artwork on his website.

To make this resource accessible to more community members, the poster is available in both English and Spanish. Download and print the PDF versions using the links below for classrooms, community events, offices, or personal learning.
