Swimming in park waters is not recommended. At normal stage, the Green River flows at a relatively brisk 4.3 knots, about 5 miles per hour, which is too strong to swim against. There is no designated swimming area in the park and no lifeguards on duty.
Swimming, wading, or bathing within 200 feet of the Green River Ferry crossing is prohibited. The area at Green River Ferry is used for the operation of the ferry and launching small watercraft. The safety of swimmers and bathers would be at risk in this area. In addition, swimmers and bathers in these areas would interfere with the efficient completion of agency functions (i.e. the operation of the ferry).
