Neither does the model account for secondary economic costs such as loss of recreation days or limitations on other economic activities such as navigation or logging. Nor does the model take into account loss of jobs. The model does not attempt to quantify how changes in the operation of the river will affect fish or other wildlife. This spreadsheet model provides a reasonable approximation of the annual costs, in millions of dollars, and other impacts on the Columbia Basin s hydroelectric system that may be expected to result from altering the operation of the hydroelectric dams. The model also shows how river flows and reservoir elevations at key locations might be affected.
