Work continued, preparing for the drawdown of Mill Pond and the release of water from Sullivan Lake. The timber crib dam continued to be removed (Photos 1 & 2). Work continued fortifying upstream unstable slopes with large woody structures (Photo 3). Work began constructing log jams to influence Sullivan Creek when it is put to the excavated starter channels (Photo 4). The delta continued to be cleared of vegetation to prevent it from washing downstream (Photo 5). Downstream, a rockery was constructed to stabilize a bank adjacent to Sullivan Lake Road (Photo 6).
The pedestrian bridge over the Mill Pond Dam was removed and a debris catchment net (Photo 1) was installed in advance of demolition of the dam. Upstream of Mill Pond Dam, Sullivan creek was rerouted to an abandoned channel (Photo 2) so that work on the delta could be completed in the dry (Photo 3), where trees were cleared and starter channels were excavated (Photo 4). These starter channels will be utilized to move the 100+ years of impounded sediments downstream during dam removal.
Please join Seattle City Light and Pend Oreille PUD staff to learn about the Mill Pond Dam removal and restoration project. This is an opportunity to share your comments about the design of the project and the related project benefits and effects.
Light refreshments and snacks will be provided.
