(Also known as Total Maximum Daily Load, or TMDL)
The Palouse River drains approximately 3,300 square miles of the Columbia Plateau in southeastern Washington and the Idaho Panhandle (see map). Eighty-three percent of the basin is in Washington State, primarily Whitman County. Several streams in the Palouse River watershed currently do not meet Washington state’s water quality standards for several parameters. To address these water quality issues the Department of Ecology (Ecology) is beginning a Water Quality Improvement Project (also know as a Total Maximum Daily Load or TMDL). A water quality improvement project is a public process in which local organizations and citizens develop actions designed to reduce pollution and bring a water body back to a healthy condition.
