The Cooperative Charting Program of the United States Power Squadrons is conducted in close cooperation with the United States Army Corps of Engineers and the United States Coast Guard. The Program is a major public service of USPS. Under it, members supply information to the above agencies so updates can be made to USACE nautical charts and the Coast Guard Local Notice to Mariners. The Aid to Navigation Inspection Program supports the USACE and Coast Guard in assuring waterways are properly marked and maintained.
