Marmot Dam & Roslyn Lake
Removal Site Tour Information
Wednesday, June 30 | 2:45-7:00 p.m.
In only two years since removal of PGE's 47' high, 345-ft-long reinforced concrete dam on the Sandy River east of Portland, Oregon, one would be hard-pressed to remember that this river had ever been interrupted with such a large structure. In fact, the Sandy River reclaimed its "natural" ownership within hours of a heavy rain event on October 19, 2007, that breached a temporary earthen dam surrounding the dam site.
During this trip, through a combination of video and printed materials, and on-site presentation from PGE staff involved in this 12-year process, PGE will describe the confluence of events - economic, regulatory, and environmental - that lead to PGE's decision to remove this almost 100-year old Bull Run Hydroelectric Project instead of renewing its federal license to operate an additional 40-50 years.
You will also visit the drained, and still recovering, Roslyn Lake site, once a pristine 160-acre body of water that provided day-use recreation for thousands of nearby residents every year while serving as the storage reservoir for waters diverted from the Sandy and Little Sandy rivers before passing through the nearby powerhouse.
PGE
is giving about 1,500 acres of Bull Run project land and other nearby holdings
to the Western Rivers Conservancy without receiving a tax deduction. This land
will form the foundation of a natural resource and recreation area in the Sandy
River Basin. Ultimately covering more than 9,000 acres, the area will be owned
and managed by the Federal Bureau of Land Management.
