Overview

The Coeur d'Alene Lake and River subbasin includes Coeur d'Alene Lake, Coeur d'Alene River, and several tributaries to these two water bodies. The subbasin contains 30 water bodies that have been listed as water quality limited under Section 303(d) of the Clean Water Act.

Following analysis of data and modeling results, 18 water bodies in the subbasin were verified to be water quality limited by at least one pollutant: eleven due to temperature, eight due to sediment, and one due to bacteria. The temperature TMDLs were deferred by the state until state temperature criteria are fully examined. The sediment limitations in the upper two segments of the Coeur d'Alene River are addressed in sediment TMDLs for the North and South Forks Coeur d'Alene River. Lake Creek, which is sediment limited, is wholly on the Coeur d'Alene Reservation, so it is not included in this TMDL. The five remaining segments limited by sediment are addressed here, as is the one segment limited by bacteria.

The impacts of heavy metals are addressed in separate documents. This TMDL deals solely with non-metallic pollutants.
