Abstract

Kellogg Creek is located in the Kellogg-Mt Scott watershed which flows through downtown Milwaukie, Oregon into the Willamette River. At the confluence of Kellogg Creek and the Willamette River is the Kellogg Dam. This dam impedes salmon, steelhead, and lamprey movement up Kellogg Creek, which is known historically as a salmon and steelhead rearing and migrating habitat. A plan to remove Kellogg Dam and restore 14 acres of Kellogg Creek is in progress by North Clackamas Watersheds Council (NCWC) and partners. Water temperature studies in Kellogg Creek have been conducted for the past several years, this report analyzed thermal surface water temperature images that were collected during a drone flight. The findings from the thermal images identified several cool water regions, ranging from 11-18°C, suitable for salmon and steelhead. The image analysis was accompanied by a literature synthesis which was used to provide recommendations on restoration design element to NCWC. These restoration recommendations suggest the implementation of stream reconstruction, application of deep pools, and increase tree canopy coverage of Kellogg Creek. These restoration recommendations are to incorporate the cool water regions identified by the thermal image analysis. The goal is that these recommendations lead to a successful restoration project and create a more climate resilient ecosystem.
