🔍 Key Concepts

• Lock approaches and guide walls – how currents and eddies behave below (downstream of) a lock • Backlash vs. set and drift – how a swirling or reverse flow differs from a simple current pushing you one way • Eddies along walls – where disturbed water is usually found in relation to the lock walls

💭 Think About

• Ask yourself: Does a backlash describe a straight current flowing into the lock, or a swirling/returning motion near a structure? • Think about what kind of water movement would be most dangerous to a vessel trying to stay clear of the lower guide wall. • Which answer choice best matches a localized disturbed current rather than a general current direction like “counterclockwise”?

✅ Before You Answer

• Focus on the word below a lock – this means downstream of the lock, not inside the chamber. • Decide whether a backlash is more like a broad current or a localized swirling/return flow near the lower guide wall. • Eliminate any options that just describe a general current direction without reference to the lock structure or guide wall.
