Name of Waterfall

Rusho Creek Falls


Rusho Creek Falls is found south of Steamboat Rock along the shores of Banks Lake in Grand Coulee. The falls can be seen next to Highway 155 about a mile south of the main entrance to Steamboat Rock State Park, or about 14-1/2 miles north of the junction of Highways 155 and 2.Rusho Creek forms a lofty 504-foot waterfall as it spills into Banks Lake flooding the floor of Grand Coulee. Unfortunately, thanks to the arid climate in this part of Washington, what would be much more impressive elsewhere in the state is reduced to a lichen stain on the cliff for the majority of the year. Rusho Creek is one of the larger tributaries to the east shore of Banks Lake, but even with the modest agricultural activity that takes place upstream there doesn't seem to be a sustained flow to the stream past the end of April. We surveyed the falls most recently in April 2017 and it was just barely flowing after the area had melted out from a significant snow fall event. It seems likely that unless there is active snow melt, or prolonged heavy rain in the immediate basin above, the falls won't likely flow with any gusto.
