The repair will necessitate the closure of the Four Locks parking lot and boat ramp from June 10-13th  2019. This repair is necessary to preserve private and public property and prevent further damage. Property owners who use this access road will be provided other means of egress.  Check our website and Facebook page for additional updates:,
