A Dam No More tells the 21st century story of one of America's first large-scale dam removals. A remarkable cast of real-life characters—including a fisherman, scientists, heavy equipment operators and weather forecasters—all have something at stake in the complicated deconstruction of Marmot Dam on Oregon's Sandy River. This is not only an epic adventure about harnessing the power of water to take out a dam; it's also a look at the relationship between humans, a river and its salmon.
