Grassy Lake Creek Habitat Enhancement

Summary: Grassy Lake Creek encompasses 5.53 square miles with 39 stream miles, located in the North Fork Nehalem watershed. To enhance habitat conditions for an isolated population of resident cutthroat trout, 19 in stream wood structures are being installed along over a mile of Grassy Lake Creek and one of its tributaries. Adding wood to the system improves boundary roughness, increases hydraulic roughness, improves sediment storage and sorting, increases nutrient sources and food web support, improves aquatic habitat complexity and increases floodplain connectivity.

Status: This project is currently in progress. The majority of the in stream wood structures were placed during the summer of 2019. The remaining structures will be installed in the summer of 2020.
