Marmot Dam Removed

OPB | Feb. 21, 2008 12:30 p.m.

In 1906 the Marmot Dam was built on the Sandy River near Mount Hood. Nearly a century later, PGE decides to remove it. But will the tons of sediment built up behind the dam harm the river downstream once the structure is removed? The National Center For Earth Dynamics at the University of Minnesota and other experts weigh in. See what happens as the Marmot Dam is removed!
