Above is a picture of the dried up Roslyn Lake bed. It is the "After" picture. To see the "Before", please click here.
The lake was a part of the The Bull Run Hydroelectric Project, a Portland General Electric development in the Sandy River basin. Originally built between 1908 and 1912, The project used a system of canals, tunnels, wood box flumes and diversion dams to feed a remote storage reservoir and power house. The entire project has now been removed due to rising environmental costs. Marmot Dam was removed in fall 2007, and PGE removed the Little Sandy Dam in the summer of 2008. After that, Roslyn Lake was left to dry up, and this is what it looks like today.
