Riparian understory dynamics and relationship to dams on the Elwha River, Washington
… At present, two dams are being removed along the Elwha River (Washington, USA), providing a valuable window for ecological studies concerning the effects of dams, and their removal, on biotic communities. In this study I described plant community dynamics along the twice-dammed Elwha River for use …

Vegetation colonization within exposed reservoirs following dam removal on the Elwha River, Washington
… succession following removal of two dams on the Elwha River, Washington. In addition, I compared patterns of vegetation among the two reservoirs and their landforms. To do this, I sampled 67 100m² plots in 2013 and 60 100m² plots in 2014 along 10 transects within Mills and Aldwell Reservoirs. …

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
… crucial as dam removal becomes more common. The Elwha River, Washington, is the location of the largest dam removals to date and provides an unprecedented opportunity to explore questions related to dam removal and riparian vegetation. The objectives of this study were to 1) look at how riparian …

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 …
