    Hiking

    Constructed in 1912-1913, the 47-foot-tall concrete dam served to divert water from the Sandy River into the Little Sandy River. In 2007, after decades of increasing maintenance costs and concerns about environmental impact, the dam was decommissioned and removed. This marked the largest dam removal project in Oregon's history and the tallest dam removed in the Northwest in 40 years.
