More than 30,000 small dams currently block river tributaries from Maine to Maryland. New initiatives to remove them are aimed at restoring natural flows, improving habitat for aquatic life, and reopening thousands of river miles to migratory fish, from shad to American eels.

Coastlines Around the World Are Losing Sediment – EOS

Just to the northeast of this image, the Yukon River empties into the Bering Sea and brings a large quantity of suspended sediment with it (courtesy of NASA - image was collected on June 13, 2018 by Landsat 8).

A new tool maps coastal sediments on the basis of water color. It shows that 75% of the world’s coastlines may be losing suspended sediment.

The Other Side of the World’s Largest Dam Removal – Hakai

The Klamath River runs more than 250 miles from Oregon’s high desert interior to the Pacific Ocean in northern California and is the site of the world's largest dam removal project. The dam decommissioning effort, which is intended to improve water quality and fish habitat, includes restoration of 2,000 acres formerly overtaken by the hydroelectric dams, which were built between 1918 and 1962 (Courtesy of Oregon State University, CC BY-SA 2.0 via Flickr).
