Abstract

Bed elevation, feature adjustments, and spawning use were monitored at three Chinook salmon spawning habitat rehabilitation sites to measure project longevity in a regulated river, Mokelumme River in California. Of the mechanisms monitored, gravel deflation was the greatest contributor to volumetric reductions, followed by hydraulic scour. As sites matured, volumetric reductions decreased. While complexity is an extremely important aspect of ecological function, artificial production of highly diverse and complex habitat features may lead to limited longevity without natural rejuvenation
