1996 Map of Dog River

About this map

Upper Hood River Valley terrain dominates this 1990s U.S. Forest Service study, illustrating the complex infrastructure required for high-elevation water management and recreation. The eastern portion of the map is defined by the Watershed Management Unit, which includes The Dalles City Waterworks and a series of gaging stations along the South Fork Mill Creek. This area provides a clear look at how glacial melt from features like the Newton Clark Glacier is captured and diverted through an intricate system of flumes and ditches, including the Volmer Ditch and Glacier Ditch.
