Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

Creator:

Stewart, Gregory B.

Abstract:

Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...

Dam removals and downstream bar-pool morphology

Creator:

Zunka, John Page Purnell

Abstract:

Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...

A summary of investigations of the use of hatchery-reared steelhead in the management of a sport fishery

Creator:

Wagner, Harry H. and Oregon State Game Commission

Abstract:

This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...
