According to the United States Geological Service (USGS) formula, a cubic foot per second (CFS) of water is equal to 7.48 gallons.

On March 13, Conemaugh Dam discharged 10,400 CFS which is equal to:

• 77,792 gallons a second or enough water to flush a standard toilet 15,558 times
• 4,667,520 gallons per minute or enough water to fill 3,218 – 21-foot, round swimming pools
• 280,051,200 an hour or enough water to take 3,734,016 – 15-minute showers
• Using a 20-ounce glass, it would be filled 4,977,868 times in one second

Water – what an amazing resource.
