The Portland General Electric (PGE) Bull Run Hydroelectric Project was decommissioned beginning in 2007. A series of studies were initiated to predict and/or monitor the effects of the removal of Marmot Dam in 2007 and the Little Sandy Dam in 2008.

The following are different projects of the sub-type Little Sandy Dam/Marmot Dam Removal Effects that have occurred in the Little Sandy1 reach.

Alternatively, you can see details on all projects of the sub-type Little Sandy Dam/Marmot Dam Removal Effects in the Sandy River Basin.

The Little Sandy Dam was removed in 2008. Cross-sectional and longitudinal transects measured below the dam site before and after dam removal will be compared to look for down-cutting or aggradation of the stream bed. The results will guide managers in their restoration efforts.
