Forecasting Flood Levels -- If a period of rain has been heavy throughout the Potomac River watershed, the river height at the Paw Paw gauge can be an early indicator of high water at Sycamore Island. Past observation suggests the water level at Little Falls will be half that of the Paw Paw gauge about 36 hours after the crest stage at Paw Paw.
