What does one prolonged blast plus one short blast signal to a river lock attendant?

Answer 1

This horn sounding pattern is not listed under the US Inland Rules, so the pattern that you mention was created by the particular jurisdiction.

Answer 2

A trip on the Muskingum River Parkway is not complete without going through one of the ten locks. These manually-operated locks are similar to those built throughout the United States before the turn of the century. Contact the park office for current fee rates when planning your trip.

When approaching the locks, boats must stay between the red and green buoys which mark the river's navigable channel. Boats approaching the lock must give a signal of one long whistle blast followed by one short blast at least 800 feet away from the lock. Boats must stay at least 300 to 400 feet clear of the lock until signaled by the lockmaster that they may enter. When entering or departing a lock, speed should be reduced to produce no wake and possible damage to other boats.
After entering the lock, boaters must secure their craft to mooring cables on the lock walls. The lockmaster will assist this procedure. Boaters must stand by to take in or let out the mooring line in relation to the water level. Each boater must provide their own mooring line of at least 75 feet.

The lowering or raising of the pool level will begin only after all lines are secure. By opening the upriver valves, water is allowed to flow slowly into the lock chamber bringing the water and boats up to the required height. When opened, the downriver valves allow the pool level to drop slowly.

After the lock pool has reached the desired level, the lock gate is opened. The lockmaster will signal that all is clear and the pilot may move his boat from the lock. The lockmaster is in complete charge of the operation and control of the locks and may determine the number of watercraft to lock through.

Is that the one that means open quickly I have a cocktail party to get to and that is more important than the rush hour traffic of all those cars up there?
