Seasonal Lock Schedule

With summer approaching, recreational boaters will once again be enjoying Pittsburgh’s Three Rivers along with the navigation industry. With that in mind, the U.S. Army Corps of Engineers will be changing the hours of operation of locks on the Allegheny and Monongahela Rivers with seasonal schedules beginning in the spring.

   (Note: Under unusual circumstances, appointment lockages will be authorized for groups of recreational boaters or individual boaters, if an emergency situation warrants.)
   
   
4. Except for the times noted in the paragraph below, commercial operators desiring appointment lockage during non-operating hours at Morgantown, Hildebrand and Opekiska must make arrangements at least 24 hours in advance by calling Point Marion L/D (724-725-5289 or 724-725-1283) between the hours of 7:30 AM and 3:00 PM.

6. As always, for this appointment procedure to operate smoothly, communications between the vessels and the locks must be continuous. In this way, neither vessels nor lock operator should experience any extended waiting times when unexpected conditions cause a vessel to vary from its scheduled appointment. Captains or pilots on the vessel should also communicate immediately with the lock personnel at Point Marion L/D when fog or other river conditions will delay their arrival. In an emergency, if contact can not be made directly with Point Marion L/D, the message can be sent through Grays Landing L/D (724-583-8304) or Maxwell L/D (724-785-5027).
   
   
7. Waterway users are cautioned that warning signs and pillar buoys will not be set until approximately mid-May. Since the navigation aids may, at time, move off station during the year because of river conditions, boaters must approach all locks with extreme care, expecially when proceeding downstream. Everyone is urged to consult their navigation charts to be absolutely sure of the landmarks when approaching a lock and dam.
   
   
8. All waters immediately above and below each dam are designated as restricted areas year round. Boaters, fishermen, divers, and other are cautioned not to enter the restricted areas, as designated by the signs and "KEEP OUT" buoys, as these areas are extremely hazardous. Upstream of the dam, currents may draw boats into the dam. Downstream of the dam, backwash and turbulenc from the dam may draw a boat into the dam, causing it to capsize.
   
   
9. Beginning January 2009 the Pittsburgh District's Notices to Navigation Interests will only be available by downloading from the Pittsburgh District webpage at www.lrp.usace.army.mil/or/orf/navrpt.htm.
