Detailed Description

This PlaneCam video was produced by developing animation tracklines in ArcGlobe, using imagery from PlaneCam flights.

From 2011-2014, a team of federal, state, tribal, academic, and community partners worked to remove two large dams—the Elwha Dam and Glines Canyon Dam—on the Elwha River in Washington State that had blocked salmon and sediment passage for almost 100 years. More than 20 million tons of sediment were released–several decades' worth of accumulation–which significantly altered the river channel and floodplain. Woody debris that had been held behind the dams was dispersed along the river’s length downstream of the former reservoirs, Lake Mills and Lake Aldwell.
