1. The Lower Coquille Watershed, part of the Coquille Basin is located in Southwest Oregon in Coos county (see figure 1). The Coquille River is the major river system which includes four stems: South Fork, Middle Fork, North Fork and East Fork. They join to become the Main Stem or Lower Coquille River. Figure 7.
