We also evaluated how dam removal on the Elwha River influenced bull trout estuarine occupancy by sampling before, during, and after dam removal, because this process enlarged the estuary but also increased turbidity and sediment transport in the lower river. Catches were ...

The largest dam removal in U.S. history hopes to restore salmon to the Elwha River. But will the salmon come home? PLAY PART ONE THE RIVER The Elwha River begins deep within Olympic National Park. It cuts through the mountains for forty-five miles before meeting the Strait of Juan de ...
Opportunistic use of estuarine habitat by juvenile bull trout, Salvelinus confluentus, from the Elwha River before, during, and after dam removalJuvenile bull troutEstuaryTimingDam removalElwha RiverEstuaries are used by anadromous fishes, either as the definitive marine habitat or as transition ...
The main goal of the Elwha weir project is to evaluate trends in abundance and diversity of Chinook salmon Oncorhynchus tshawytscha and steelhead trout O. mykiss in the Elwha before, during and after dam removal. In 2010, a 59.4 meter resistance board floating fish weir was installed and ...
Before dam removal, anadromous fishes were limited to the 7.9 km section of river downstream of Elwha Dam, potamodromous species could not migrate throughout the river system, and resident trout were the most abundant species. After dam removal, there was rapid passage into areas upstream of ...
Relocations of Bull Trout in the tidal zone and the presence of bright, silvery colored adults were indicative of marine residence. Length at age of Bull Trout significantly increased after dam removal, and fish captured before and after dam removal were larger at similar ages when compared to ...
We used terrestrial laser scanning, high-resolution orthoimages, and surveys of large wood (LW) and sediment grain-size distribution to quantify changes to the channel and LW in four different geomorphic settings spanning a 16-year period before, during, and after dam removal. The results ...
The river system showed a two- to tenfold greater geomorphic response to dam removal (in terms of bed elevation change magnitude) than it had to a 40-year flood event four years before dam removal. Two years after dam removal began, as the river had started to incise through deposits of...
