Abstract

The Kenai River in south-central Alaska supports a multi-million-dollar, world-class salmon fishery. Recent studies indicate that numerous aquatic-habitat features along the river can be directly attributed to the effect of glaciers in its watershed. An extensive period of sustained high flows during salmon migration, two large glacially sculpted lakes, coarse streambed material, and a stable channel are examples of glacier-affected features. The extent of the watershed covered by glaciers significantly affects the seasonal and daily fluctuation in streamflow and the concentrations of suspended sediment. The historical extent of glaciers in a watershed has influenced channel morphology and stability. The glacial influences subsequently affect aquatic-habitat attributes such as protective cover, navigable water velocities, and appropriately sized substrate, which are most important to rearing juvenile salmon in the Kenai River.
