Vegetation community development after dam removal on the Elwha River
<p>The Elwha River is the site of the largest dam removal project in the world to date and serves as a case study for the ecological effects of large dam removal. The 2012-2014 removal of two dams on the Elwha River exposed a cumulative 2.76 km2 of previously inundated surfaces. Environmental …

The Elwha River Restoration: Landscape Change, Salmon, and Sense of Place
<p>Removal of the Elwha River dams to restore the ecosystem and salmon fisheries is the largest project of its kind in the history of the United States. Spanning decades and affecting generations, this project has changed and will continue to change the landscape. This research examined the …

Riparian understory dynamics and relationship to dams on the Elwha River, Washington
<p>"Dams alter the dynamics inherent to river systems by displacing natural hydrologic and sediment regimes, which can fundamentally alter riparian ecosystem function. However, with better understanding of how dams negatively impact river systems, and as many dams approach the end of their …

Raw Material Usage and Stone Tool Manufacture in the Elwha River Valley
… investigations stemming from the removal of the Elwha and Glines Canyon Dams of the Elwha River Valley in 2014 resulted in the identification of nine archaeological sites and collection of 6,870 pre-contact lithic artifacts, primarily composed of fine-grained volcanic stone. Regional models of …

Vegetation colonization within exposed reservoirs following dam removal on the Elwha River, Washington
… are important for ecological functioning of rivers, and are significantly impacted by dams. With over 50% of large dams in the U.S. beyond their life expectancy, dam removal is increasingly being considered to eliminate aging infrastructure and restore ecosystems. There have been few large …

Initial response of riparian vegetation to dam removal on the Elwha River, Washington
… riparian zones can be altered by the damming of rivers that disrupts natural fluvial processes that change the flow regime, trap and reduce sediment transport downstream, and limit the dispersal of seeds in the water column. On some rivers, dams reduce floristic diversity downstream and create …

Revegetation of two drained reservoirs on the Elwha River ten years after dam removal
<p>The Elwha and Glines Canyon dams on the Elwha River, Washington, USA were removed between 2011 and 2014 after being in place for a century, and at the time were the largest dams ever removed. The resulting dewatering of Lake Aldwell, the reservoir of the Elwha dam, and Lake Mills, the reservoir …

Long-term Geomorphic Effects of the Glines Canyon Dam Removal on the Elwha River, Washington, USA
<p>The Elwha River once provided vital habitat for a variety of salmonid species, but after two dams were emplaced on the river in the early 1900s, habitat diminished, and salmon populations declined. From 2011-2014, the dams were finally removed to restore the Elwha ecosystem. To understand the …

Riparian vegetation and the soil seed bank five years after dam removal on the Elwha River, Washington
<p>Damming of rivers is widespread and can profoundly impact riparian areas by altering the fluvial processes that drive riparian vegetation communities. Dam removal may reverse these effects; however, very few studies have examined the response of riparian vegetation to large dam removal and …

Quantifying Channel Responses to the Removal of the Glines Canyon Dam in the Middle Reach of the Elwha River, Washington
… study sites throughout the middle reach of the Elwha River were monitored before, during, and after the dam removal process over a period of two years from 2012-2014. The complexity of the river geometry was a major factor in the ability of the river to trap and accumulate the new influx of …

Monitoring the influx of marine derived Nitrogen and characterizing soil food webs of riparian zones of the Elwha River Watershed, WA, USA.
… The recent removal of two large dams on the Elwha River, WA, opened up ~60 km of previously inaccessible river habitat for pacific salmon. I used naturally abundant stable nitrogen isotopes (denoted as ‰ δ15N) to establish baseline data to monitor the influx of MDN to riparian zones of Elwha …
