THE RED RIVER SURVEY. 



A traverse was run along the Bois de Sioux and Red Rivers from 

 the lower end of Lake Traverse to the international boundary, a 

 distance of about 435 miles. This traverse was tied in to section and 

 township corners at all township lines. South of Wahpeton the 

 lines were run by needle, while north of Wahpeton azimuth was used. 

 The traverse was tied to the range lines. As accurate maps of Lake 

 Traverse and surrounding areas were available, a survey of that part 

 of the valley was not necessary. 



All elevations are referred to mean sea level, the survey having 

 been based upon bench mark elevations as determined by the United 

 States Coast and Geodetic Survey in the 1912 adjustment. Ties were 

 taken to permanent bench marks set by the Coast and Geodetic 

 Survey and the Geological Survey at various points in the valley, the 

 elevations of which are given in Table 2.
