Elevations are shown thus: +2, indicating height in feet above CRD.
Control is by USACE and NOS-C&GS.
Soundings are shown in feet and indicate depths below CRD.
Horizontal coordinates are based on the Lambert Projection for Oregon, North Zone (NAD 83, U.S. Survey Feet).
The project depth curve is shown thus:
Committee, Pacific Northwest River Basin Commission,July 1972.
River mileage conforms to the River Mile Index of the Hydrology and Hydraulics
Aerial Photography taken by U.S.D.A. Fall 2009.
Reference is Navigation Chart No. 18525.
