M252-20 (T) Charted Depths – River Derwent, Ross Bay

Mariners are advised that a recent hydrographic survey undertaken on the foul ground east of Ross Bay has determined some variation and reduction to the depths currently on the chart.

Mariners should exercise caution when navigating in the area and be conscious that the current charted depths may not be reliable. Once the recent hydrographic survey is finalised, updated depths for the area will be formally declared.
