The study area is shown on the Mount Rose and Washoe City 7.5 minute U.S. Geological Survey quadrangles. The creek flows to the east where it joins Steamboat Creek. Estimated thickness of the alluvial material is believed not to exceed 1000 feet with a surface elevation range of 5000-6500 feet. Watershed elevation ranges from 10778 feet atop Mount Rose to 4730 feet at the confluence with Steamboat Creek. Galena Creek watershed can be conveniently divided into two approximately equal area regions, the upper and lower watershed.
Division is based on a break in vegetation, slope and anthropogenics.
Recent population increases have resulted in several housing developments and other impermeable surfaces.
