Course
The Union River originates in central Kitsap Peninsula a few miles west of Bremerton, east of Green Mountain and northeast of Gold Mountain. It flows south and slightly west. The river is impounded in its upper course by Casad Dam, creating the Union River Reservoir. Shortly downstream from the reservoir the river plunges over McKenna Falls. The East Fork Union River joins the main stem, below which the Old Belfair Highway runs through the river valley, paralleling the Union River. Near the town of Belfair the Union River empties into the extensive mud flats of Lynch Cove at the end of Hood Canal.
