HISTORICAL PERSPECTIVE:
 The Coeur d'Alene River Basin is the origins of the Spokane River flow, also. This  basin is located mainly in the Coeur d'Alene Mountains of Northern Idaho, but also extends to an  immediate input area in east-central Washington state.

WATERSHED:
The Coeur d'Alene River Basin and the associated St. Joe/St. Maries basins make up the drainage area of  Coeur d'Alene Lake .  The Coeur d'Alene River Basin is subdivided into the  Upper Coeur d'Alene (North Fork) , as well as the
South Fork .  The  St. Joe River flows into Lake Coeur d'Alene from south of the Coeur d'Alene Basin.

The outflow of  Lake Coeur d'Alene at its northern end is the Spokane River.  It will flow through Post Falls, Idaho, and Spokane, Washington, and then into the Columbia River.  Between Spokane and the Columbia there is further input into the flow of the Spokane River from the  Upper Spokane Basin .

WATERSHED DATA:
The most useful data on the Coeur d'Alene River comes from a USGS station at  Cataldo, Idaho .  Historical streamflow data can be selected by years or by months per year.   Current conditions may also be found for the Coeur d'Alene River at Cataldo.  Other real-time data on the Coeur d'Alene River is available from other  stream--gaging sites in the basin.  Further information for understanding  Idaho streamflow conditions would include  temperature  and  precipitation figures for the various areas that are in the drainage basins of Lake Coeur d'Alene:  Avery ,  St. Maries ,  Kellogg ,  Wallace , and  Mullan .
