The Coast Guard is conducting Waterways Analysis Reviews of Portland Harbor and Portland Approaches. The Waterways Analysis Review is used to determine the effectiveness of aids to navigation within these waterways. Navigation aids under review will include light houses, buoys, day markers and ranges.
The following areas are under the review for Portland Harbor: Back Cove Approach, Portland Harbor, Lighthouse Channel, Mill Cove and the Fore River. Additionally, the Coast Guard will review navigation aid suitability for Portland Harbor Approach. The data gathered in the analysis will be used to alter and modify channel and hazard markings to ensure that the Coast Guard provides the most effective and efficient system possible. The last survey was completed in 1999.
