NOTES

Control is by USACE, NOS-C & GS and OSHD.

Coordinates are based on the Lambert Projection for Oregon, South Zone (NAD 83).

Datum is Mean Lower Low Water. (MLLW is 3.78 feet below National Geodetic

Vertical Datum at the Coast Guard Station, 3.38 feet at Empire,

3.74 feet at the Railroad Bridge and 3.98 feet at the C of E Dock at Coos Bay, 1947 adjustments.)

Soundings are shown in feet and indicate depths below MLLW.

Elevations are shown thus: +2, indicating height in feet above MLLW.

The MLLW plane is shown thus:

The project depth curve is shown thus:

Reference is Navigation Chart No. 18587.

The information depicted on this map represents the results of surveys made on the dates indicated and can only be considered as indicating the general condition existing at that time.
