Attachment 10 - 2024 State of the Buoys.xlsx

This is a 2024 inspection and maintenance survey report for mooring buoys located throughout the Sitka Ranger District, Tongass National Forest in Southeast Alaska. The document provides detailed condition assessments for 12 buoy locations surveyed between April and October 2024, including Sevenfathom, Allan Point Cabin, Piper Island Cabin, Neva Shelter, Moser Cabin, Appleton, Kanga Bay, Samsing, Redoubt Bay, Fred's Creek, Brent's Beach, Mud Bay, and Silver Bay/Outlet of Salmon Lake.

The inspection data includes comprehensive measurements of chain diameter at various depths (ranging from surface to 90 feet), assessments of buoy condition, anode status, anchor integrity, and associated hardware such as shackles, bails, and mousing wire. Key findings indicate widespread corrosion and pitting issues requiring maintenance across multiple locations. Specific recommendations include high-priority chain replacements at several sites (Allan Point Cabin, Redoubt Bay, and Fred's Creek), anchor replacements or repositioning at multiple locations, buoy component replacements due to tire wear and structural corrosion, and anode replacement work already completed during 2024 inspections. The report documents that divers B. Toney, A. Bolwerk, K. Winslow, and K. Sands conducted the surveys and identifies priority maintenance actions ranging from low to high, with most locations requiring chain replacement within the next 1.5 years and several requiring immediate attention.
