🔍 Key Concepts

• Lock whistle signals used by U.S. Army Corps of Engineers on inland rivers • Meaning of one short blast from the lock when the chamber is empty and gates are open • Normal sequence of lockage completion and exit for a downbound tow

💭 Think About

• Think about what the lock operator is communicating once the chamber is empty, the lower gates are open, and you are ready to move downbound. What signal authorizes the next action? • Ask yourself: does one short blast usually mean "stop/hold" or "proceed" in the context of lock operations (not meeting/crossing situations)? • Consider what the safest and most efficient action is for traffic flow when the chamber is prepared and the river below appears clear.

✅ Before You Answer

• Verify the standard lock whistle code for one short blast versus danger or malfunction signals • Confirm what the lockmaster’s signal means after the entire lockage is complete (water level set, gates open) • Make sure your choice matches an action that responds directly to an authorization from the lock rather than acting on your own assumption.
