Detailed SR Function Description
Density-independent survivorship for spring Chinook upstream migration and holding and stream temperature. Stream temperature is modelled as the 7-day average of daily maximum (7-DADM). Functional relationship is originally sourced from the Willamette River OR (see original source data from (Bowerman et al. 2018).
Regression line shows relationship for wild (non-hatchery) origin fish. Mortality increases with stream temperature

Stressor Magnitude Data
Empirical model that estimates fine sediment from road density, slope and bankfull width
PoE Chain
Upland development, road building, fine sediment, smothering of eggs, egg to fry surviorship
Function Type
continuous
Stressor Scale
linear
