Page 14-3 - ... lines are not run as boundaries, but to define the sinuosities of the banks of the stream or other body of water, and as a means of ascertaining the quantity of land embraced in the survey, the stream, or other body of water, and not the meander line as actually run on the ground, being the boundary. When by action of water the bed of the body of water changes, high-water mark changes and ownership of adjoining land progresses with it. Lane v United States, 274 Fed 290 (CCA 5, 1921) ; Harper...
Page 14-16 - RESTORATION BY SINGLE PROPORTION The method of single proportionate measurement is generally applicable to the restoration of lost corners on standard parallels and other lines established with reference to definite alinement in one direction only. Intermediate corners on township exteriors and other controlling boundary lines are to be included in this class.
Page 14-15 - A lost corner is a point of a survey whose position cannot be determined, beyond reasonable doubt, either from traces of the original marks or from acceptable evidence or testimony that bears upon the original position, and whose location can be restored only by reference to one or more interdependent corners.
Page 14-15 - MEANDERING. All navigable bodies of water and important rivers and lakes are segregated from the public lands at mean high-water elevation. The traverse of the margin of a permanent natural body of water is termed a meander line.

It is applicable for large areas and long lines and is used for the precise location of basic points suitable for controlling other surveys. geodetic zenith— The point where...
Page 14-13 - Preliminary to the subdivision of quarter sections, the quarterquarter or sixteenth-section corners will be established at points midway between the section and quarter-section corners, and between the quarter-section corners and the center of the section, except on the last half mile of the lines closing on township boundaries, where they should be placed at 20 chains, proportionate measurement, counting from the regular quarter-section corner.

Page 1-3 - A survey executed for the purpose of obtaining information that is essential for planning an engineering project or development and estimating its cost. The information obtained may, in part, be recorded in the form of an engineering map.
Page 14-16 - In order to restore a lost corner of four townships, a retracement will first be made between the nearest known corners on the meridional line, north and south of the missing corner, and upon that line a temporary stake will be placed at the proper proportionate distance ; this will determine the latitude of the lost corner. Next, the nearest corners on the latitudinal line will be connected, and a second point will be marked for the proportionate measurement east and west; this point will determine...
