Description

This restoration project will address high priority ecological concerns in Nason Creek by establishing a perennial side channel with connection to off channel wetland habitat, installing wood structures to increase instream complexity and habitat, and establishing riparian vegetation in the floodplain and newly created side channel. The project is located on Chelan-Douglas Land Trust property at RM 10.8 - 11 on Nason Creek. The project will benefit ESA listed spring Chinook salmon, steelhead, and bull trout in Nason Creek. Project work will include limited invasive plant control and riparian plant removal when needed to achieve project goals.

Project Benefit

The goal of this project is to improve abundance, productivity and spatial structure for ESA-listed species by addressing the highest priority ecological concerns in Nason Creek, which is the highest priority Assessment Unit for restoration in in the Wenatchee watershed. The ecological concerns that this project will address in priority order are:

1) Peripheral and Transitional Habitat (Side Channel and Wetland Connections)

2) Channel Structure and Form (Bed and Channel Form)

3) Riparian Condition

4) Channel Structure and Form (Instream Structural Complexity)
