Wenatchee Valley: Nason Creek Floodplain Re-connection Project

Date
Time
7:00pm - 8:30pm

Washington Native Plant Society monthly program.

Jennifer Hadersberger, Senior Natural Resources Specialist with Chelan County Natural Resources Dept., will provide an overview of the stream restoration project as well as a discussion of lessons learned during the revegetation contracting and native plant installation. In the late 1950’s, approximately 1 mile of Nason Creek was constricted into a narrow channel flowing between two constructed levees that protected the Chelan PUD powerlines to the north and the BNSF railroad to the south. The existing stream bed was incised due to channelization and Nason Creek was disconnected from the adjacent 30 acre floodplain wetland to the north. This project removed ~0.5 mile of the river left levee, re-located ~1,400 linear feet of straightened mainstem into a new meander alignment, and re-connected ~30 acres of channel migration zone. Site re-vegetation efforts included seed collection within the Nason Creek watershed and growing out over 15,000 native plants to restore the 10+ acre work area.
