90th Anniversary of Bull Run Storage Dam 1

This year marks the 90th anniversary of the completion of the Bull Run Storage Dam 1. The construction of the storage dam was just one phase of a project to expand capacity in the Bull Run Reserve. The project was set in motion to address the growing population in the Portland metro area. To this day, the City still relies heavily on the water supply stored behind Dam 1. The Portland Archives & Records Center’s new exhibit highlights the three-year construction project that ended in 1929, and includes photographs, drawings, maps and correspondence.

Drop by our office at 1800 SW 6th Ave, Suite 550 to view the exhibit. If you are at City Hall, you can find a supplemental display in our exhibit case located on the 1st floor. Exhibit materials are also available through our online database Efiles. See
