Waterways Analysis and Management System

This analysis, officially known as a Waterways Analysis and Management System (WAMS) study, is a tool the CG uses to plan and implement our Aids to Navigation Program (ATON). WAMS are conducted every five years on each Federally designated "Navigable Waterway".


Studies are normally announced in the USCG's, weekly "Local Notice to Mariners," and occasionally by other additional means such as the media or via direct mailings. The USCG looks for two primary results from the WAMS; first and foremost, we look to see what may be done to enhance the safe navigation upon a waterway during the next five years. And secondly, we use the data we collect to anticipate and plan our budgeting process, at both the regional and national levels, over the same timeframe.

In conducting a WAMS the report writer solicits user input, rides at least one USCG and commercial vessel (and if available, other DOD, federal, state and local govt. vessels) to view the waterway firsthand. They also review existing navigational literature (Charts, Coast Pilots, Light Lists, Sailing Directions, ...) used by the mariner on a waterway with an eye to accuracy. In general anything that "may" affect safe navigation on the waterway including, but not limited to, geological and other physical changes in the characteristics of the waterway (either manmade or natural), changing political or economic trends, accident (pollution/vessel) reoccurrence rates in the vicinity of any navigational aids or specific portion of a waterway, and sensitive military or environmental issues.


The studies mandated by congress are a very important tool both for the Coast Guard and the Users. Your input is valuable and appreciated.
