Spawning habitat for Chinook salmon in the North Santiam River, Oregon
This data release contains rasters of modeled spawning habitat for spring Chinook salmon at a range of streamflows in the North Santiam River, Oregon, extending from Big Cliff Dam downstream along the North Santiam River to a point near Stayton, Oregon. This area approximately encompasses the main river extent where spring Chinook salmon spawn in the North Santiam River downstream of Big Cliff and Detroit Dams (Stockwell and others, 2025). Usable habitat area for spawning spring Chinook salmon was evaluated by integrating depth and velocity outputs from two-dimensional hydraulic models (Bartelt and White, 2026) and estimates of riverbed grainsize (White and others, 2025) with observed and literature-based Chinook salmon habitat preferences (White and others, 2026). Grainsize estimates include the D50 (median surficial sediment size) and D84 (84th percentile surficial sediment size), which are used to characterize the proportion of the riverbed where substrate particles are of a sufficient size for building nests (redds) and movable by spawning Chinook salmon (White and others, 2026). The resulting rasters of modeled spawning habitat for the North Santiam River are organized into three subreaches (described in enclosed README file). For each reach, rasters of spawning habitat are included for a range of streamflows that span typical streamflows during the spring Chinook salmon spawning period of mid-August to late-October. Users are encouraged to read White and others (2026) and the enclosed README file for descriptions of model development, habitat preference criteria selection, and limitations.
