We invite you to comment on the Little Spokane River draft water quality improvement plan.

We have drafted the Little Spokane River Dissolved Oxygen and pH water quality improvement plan. This draft water quality improvement plan aims to address two issues in the river, low dissolved oxygen and high pH levels. The goal of the water quality improvement plan is to identify water quality and riparian habitat improvements needed to support aquatic life and recreational uses in the Little Spokane River watershed. Once finalized and implemented, this plan should lead to more functional habitat for mountain whitefish, redband trout, and other species and ensure safe swimming, fishing, and boating.

The federal Clean Water Act requires states to develop a Total Maximum Daily Load (TMDL) — or water quality improvement project — plan for each water body on the state's polluted waters list, also known as the 303(d) list. This science-based approach assigns a numerical value that represents the highest amount of a pollutant a surface water body can receive and still meet the water quality standards.
