Introduction

Located in northeast Washington, the Colville National Forest covers approximately 2,123 square miles.  The forest is situated within Pend Oreille, Stevens, and Ferry counties. Communities adjacent to the forest include Colville, Chewelah, Kettle Falls, Republic, Newport, Ione, and Metaline Falls.  The forest is bordered by Canada to the north; Okanogan National Forest to the west; Idaho and the Idaho Panhandle National Forests to the east; and Colville Confederated Tribal lands along the southwestern portion of the forest.  Four ranger districts manage the forest:  Three-Rivers, Republic, Sullivan Lake, and Newport.

Water quality issues

Water monitoring data on the Colville National Forest showed several streams did not meet fecal coliform bacteria and temperature standards.

What was done?

Ecology began working with the Forest Service on a water quality improvement project (also called a total maximum daily load or TMDL) for the Colville National Forest in 2002.  The TMDL is only for waters in the national forest - not private lands within the boundary.

Status of the project

EPA approved the Water Quality Improvement Report on August 5, 2005. Ecology and the Forest Service finalized the Water Quality Implementation Plan in Oct. 2006.
