Maine – Portland Harbor

This coastal survey was made in Washigton D.C. by the U.S. Coast and Geodetic Survey on February 12, 1945 . Portland Harbor in Maine is illustrated on this map. Details include depth readings, restricted areas, prohibited areas, the names of important cities along the coast, some important buildings, railroads,and major roads. Most recent corrections, pipeline and cable areas, bouys, beacons, and lights, and special anchorages are stamped on the map Notes on the map read: Warning: Aids to navigation may be altered, interrupted or removed without notice. In general, temporary changes due to war conditions are not incorporated on the chart. Caution Improved Channels- The side limits of the improvement are shown by broken lines. The controlling depth through the channel, on the date given, is placed in or alongside the channel, or in a seperate note, but no depth greater than the project depth is given. Because of possible shoaling, particularly at the edges, it must not be inferred that the depth stated exsisted throughout the entire width of the improvement on the date of the examination unless so stated, or that it has not since decreased in places across the entire width.
