- The page defines wait as the time between a tow’s arrival at a lock and the start of its lockage.
Field notes
Visitors can sort the lock directory by river and mile, lockages, barges, median commercial wait, or tows waiting now; the page defines wait as arrival-to-start-of-lockage time. Its listings distinguish zero-valued results from “No commercial wait sample” and span routes from the Columbia to the Atchafalaya. The homepage also links to busiest-lock and methodology pages.
