Pine Hollow-Jackknife Creek Watershed Assessment
Sherman County, OR
Cascade assisted the Sherman County Soil and Water Conservation District with the completion of an assessment of Pine Hollow and Jackknife Creeks, a nearly 150,000 acre watershed draining to the lower John Day River in north-central Oregon.
For this project, we analyzed data, developed GIS and other databases, and summarized the findings. We produced a comprehensive series of maps depicting watershed resources, water quality and quantity, habitats, and fish population statuses. The assessment describes the watershed within the context of the larger John Day Basin’s ecological setting and its contribution to ESA-listed steelhead population recovery.
In the assessment, we analyzed the factors limiting steelhead and redband trout populations and made recommendations for prioritized stream, riparian, and upland restoration actions. The watershed assessment is useful both as a technical guide for land managers and a resource to facilitate landowner outreach and stewardship.
