DESCRIPTION
In partnership with the Methow Conservancy, Cascade Fisheries developed restoration concepts in a two mile reach of the Upper Methow (RM 72-74), where decades of floodplain encroachment have diminished quantity and quality of habitat for ESA-listed spring chinook, summer steelhead, and bull trout. Over the last two decades, the Methow Conservancy has secured (easement and fee simple) many contiguous parcels in this reach, with a goal of protecting existing high-quality habitat and facilitating improved floodplain function.
CF compiled available data, identified and filled data gaps, initiated stakeholder outreach, and developed three restoration concepts and an assessment for a protection strategy in support of working toward developing ecologically beneficial and socially feasible projects in this high-priority reach of the Upper Methow River. Restoration concepts included levee removal, mainstem log jams, and removal of floodplain barriers. Due to the location of many properties within the floodway, the risk to properties identified in hydraulic modeling of proposed conditions for these projects was not substantially different than that of existing conditions. However, the continued private ownership of many parcels, and the existence of several houses in close proximity to the river, supports the need for more extensive protection and possible structure relocation in order to facilitate any substantive restoration project proposed for the reach. CF will continue working with the Methow Conservancy, the Confederated Tribes of the Colville Reservation, private landowners, and future possible funders to work toward sufficient protection in the reach to enable future large-scale restoration of floodplain processes.
The 2016 PCSRF funds were spent within the award period.
