SURVEY CONTROL POINTSLEGEND
BASIS OF SURVEY DATUM
This project uses a custom local coordinate system designed for the Whitetail Dam project site. Control marks for this project is included herein. The coordinate system started as the Montana State Plane Coordinate System, but was brought to ground at CP-1 with a ground scale factor of 1.0003815920. To avoid confusion with true SPC coordinates, project coordinates were truncated 400,000 in the Northing and 3,100,000 in the Easting. The geodetic datum is NAD 1983 (2011). The vertical datum is NAVD88 as determined by GEOID12B. Horizontal units are international feet. Vertical units are survey feet.
For the purposes of this project, mapping grid values and distances are equal to true ground distances. The convergence angle at CP-1 is +3°30'02"; the convergence angle at point CP-5 is +3°29'42".
DOWL established project control with an OPUS position at CP-1. Values for points CP-2 through CP-6 were determined by RTK GPS observations from CP-1.
