Coast Guard conducts waterways analysis study of Tillamook Bay, seeks public comment

SEATTLE — Coast Guard officials are seeking public comment while conducting a waterways analysis and management system (WAMS) review of Tillamook Bay, Ore.

The Coast Guard uses WAMS to validate the adequacy of the existing aids to navigation (ATON) system, as well as to get a better understanding of the uses of each waterway and general safety issues.

WAMS focuses on the waterway’s present ATON system, marine casualty information, port/harbor resources, changes in marine vessel usage (both recreational and commercial) and future development projects. WAMS reviews are conducted every five years on each federally designated navigable waterway.
