Forty-eight archaeological sites were identified during a 1977 survey of the proposed Burlington Dam Flood Control Project site. Priority areas surveyed were the Lake Darling area, acreage downstream of Lake Darling dam to the proposed Burlington Dam site and from the head of Lake Darling to the Canadian border. These areas maintain five general eco-zones. Prehistoric human adaptations favored the Northern forest, Terrace Grasslands, and Upland Prairie eco-zones. Plains Village manifestations from the Woodland time period are located predominately in the Northern Floodplain Forest. Plains Nomadic occupants probably used both the Floodplain Forest and Terrace Grasslands. Cultural material analyses suggest tht ceramic components with a preponderance of Swan River chert lithic debitage area Plains Village manifestations. Non-ceramic manifestations with an abundance of Knife River flint debitage appear to represent Plains Nomadic cultural types. Both cultural components co-existed in the Upper Souris Valley throughout Woodland times. The 1977 survey points out two facts. First, much of the archaeological resources were irretrievably lost after the construction of Lake Darling in the 1930's. Secondly, a significant body of a data remains which must be investigated thoroughly and be mitigated on a basis equal with other project considerations. Most individual site recommendations are based on the assumption that the proposed Burlington Dam will adversely affect the known sites.
