Description    


The Columbia Land Trust used this funding to acquire and restore 116 acres of estuarine wetlands, including 2 miles of shoreline. The Grays River, a major watershed draining into the Columbia River Estuary, Wahkiakum County, is home to 5 species of anadromous salmonids: coho, Chinook and chum salmon, steelhead, and sea-run cutthroat. Chinook, chum and steelhead are listed as threatened. The Grays River supports the strongest remaining run of chum salmon in the Columbia River ESU. Limiting factors to salmonid production within the basin are varied.
The restoration work completed subsequently improved tidal connectivity to the Grays River estuary by breaching an old access road (levee) in five locations where the road impacted historic channels. Disturbed portions of the roadway were replanted with a mix of woody species including Sitka spruce and willow. Restoring tidal function to this estuary improves water quality conditions as well as increases the productivity of both the Grays River and in the Columbia estuaries. This project benefits upriver Columbia Basin anadromous fish dependent on the Lower Columbia River estuary for juvenile nursery habitat. A number of state, federal and private partners were involved including Ducks Unlimited and Washington Department of Fish and Wildlife.

Project Benefit    


The goal of the project is to protect and connect isolated habitat to increase the range and distribution of salmon. The objective of the project is to protect and increase access to freshwater in-stream side channels, oxbows, and other channels.
