DESCRIPTION
The Pysht River estuary was historically used for the marine transport of logs between 1915-1975. To do so, the lower river was channelized and dredged using both suction and clamshell dredges. Dredge materials were discharged onto salt marsh or placed along channel margins. As a result, significant areas of the Pysht River estuary were disconnected from the river and or converted to upland vegetation types. Suction dredge deposits first appear in the 1951 aerial photograph series and form a series of interconnected, large mounds on what was formerly tidal marsh in the northwest portion of the estuary. Removal options for these deposits have been explored in the recently completed Pysht River Estuary Restoration Feasibility Study (30% design). This current project involved completion of a final design and permitting for the removal of suction and clamshell dredge deposits placed on of historic salt marsh in the Pysht River estuary. This project sets the stage for project partners to secure future funding and implementation of salt marsh restoration that includes the removal of 138,500 cubic yards of fill over 21.5 acres and the establishment of ~10,000 linear feet of tidal channels. These channels will ultimately provide benefits to a multitude of species including forage fish and salmonids including Pysht River stocks of chum, coho, chinook and steelhead. Listed stocks of chinook from other areas (Puget Sound and Columbia River) have also been documented using the Pysht estuary.The final design and permit set were completed for the project during the second quarter of 2015. Unfortunately the landowners have decided not to move the project forward.
