  8. Flood Inundation Maps Excellent resource to understand your flood risk. Shows coverage and depth of flood waters. Can be used to plan evacuation routes & travel. Available at http://water.weather.gov for these points: • Chenango River at Chenango Forks & Greene • Delaware River at: Belvidere, Easton, Frenchtown, Matamoras/Port Jervis, Montague, New Hope/Lambertville, Riegelsville, Stockton & Trenton • Passaic River at: Chatham, Clifton (Dundee Dam), Little Falls & Millington • Pequannock River at Riverdale • Pompton River at Pompton Plains • Saddle River at Lodi, NJ • Susquehanna River at: Bainbridge, Binghamton, Conklin, Harrisburg, Owego, Unadilla, Vestal & Windsor • Unadilla River at Rockdale, NY • Upper Saddle River at Saddle, NJ • West Branch Susquehanna River at Jersey Shore, PA

  9. Turn Around Don’t Drown • Over half of all flood-related drownings occur when a vehicle is driven into flood water. The next highest percentage of flood-related deaths is due to walking into or near flood waters. • People underestimate the force and power of water. • Many of the deaths occur in automobiles as they are swept downstream. • 6” of fast-moving flood water can knock over an adult. It takes only two feet of rushing water to carry away most vehicles, including pickups and SUVs. • Flood waters may hide the fact that the road bed has been washed away. • Flooded roadways are particularly hard to see at night.
