This document is intended to be a practical guide for fisheries biologists and other planners in the use of the EDT model in the Northwest Power Planning Council's subbasin planning process. A good practical guide proceeds from general to specific, including a concrete example of how general principles were applied in a real-world situation. Accordingly, this manual will show how general principles were applied in developing a subbasin plan for spring chinook salmon in the Yakima River subbasin (hereafter referred to as "the Yakima").

The Yakima is a large and environmentally diverse system, with a wide range of anthropogenic impacts. This very complexity makes the Yakima a good case study, as many planners will find in the Yakima examples of problems similar to their own.

Section 1 of this Primer provides some background information on EDT and subbasin planning. Section 2 presents the general procedures and Yakima example for applying EDT to subbasin planning.
