RUNOFF PLOTS FOR SELECTED STATIONS IN WYOMING
October 1, 2003—September 30, 2004
The runoff graphs shown on these pages depict the total amount of water that flowed past a given streamflow-gaging station from October 1, 2003 through September 30, 2004. The graphs depict runoff measured at a given USGS streamflow-gaging station. For many streams in Wyoming, most of the runoff occurs during a snowmelt runoff period that generally begins in April or May, and ends by late July. For these snowmelt-dominated streams, as much as 80% of the annual runoff occurs during this snowmelt runoff period.

Annual runoff Annual runoff is the total quantity of water that is discharged (“runs off”) from a drainage basin in a year. Annual runoff data are often presented as volumes in acre-feet. An acre foot is the volume of water that would cover one acre to a depth of one foot and equals 43,560 cubic feet or 325,851 gallons.
