The United States Geological Survey (USGS) monitors Virgin River flows and measures water volume in CFS, or cubic feet per second. The CFS of the Virgin River fluctuates over time, rising or falling as a result of rains, snow melt, and air temperatures. Zion National Park uses the current CFS reading as a reference tool to gauge safety conditions in The Narrows and regulate access.
