Depth on Bar
Depth on Bar.
As soon as the West breakwater had reached a length of 2800 feet, and before the East breakwater had been commenced, the bar began to deepen, and the depth has steadily increased with the extension of the breakwaters, until within the last two years, when it has apparently become stationary, averaging within a few feet according as the river is low or flooded. The following table, prepared by your Engineer from records kept by the Harbormaster, shows very clearly the influence of the works upon the depth of water on the bar. From this it appears that before the works began the usual depth of water on the bar was from 9 to 14 feet, and since the completion of the works the usual depth is from 18 to 25 feet These depths are taken at high water, the rise of tide being from 6 to 10 feet.
