S ounding and elevations are in feet and refer to the plane of NOS Mean Lower Low W ater (MLLW ). Epoch 1983-2001. T ide correction Based on Geoid03 using R eal T ime K inematic (R T K ).

Horiz ontal Datum: W GS -84. P rojected coordinate system: Lambert Grid P rojection, S tate P lane, W ashington S outh Z one, 4602, S urveyed in North American Datum of 1983/2011, P lotted in North American Datum of 1983/91.

Horiz ontal units are U.S . S urvey Feet.

T he information depicted on this map represents the results of surveys made on the date indicated and can only be considered as indicating the general conditions existing at that time.

S oundings tak en above the datum plane are prefixed with a (+) sign.
