Every safe arrival and departure from the numerous harbors in Puerto Rico is made possible by a team of professionals working quietly but relentlessly to ensure Federal navigation channels are open, secure, and ready for whatever comes next. To ensure the continued safety of these harbors, in July 2025, the U.S. Army Corps of Engineers Caribbean District Operations Branch – in partnership with the Charleston District – carried out hydrographic surveys at the Harbors of Ponce, Mayagüez, and Arecibo. These surveys were not just routine; they were a vital part of the Corps’ mission to maintain safe navigation and interstate commerce across the region.
