Abstract: A potential site for construction of a series of earth dams and dikes with a maximum height of 335 ft, the Dickey-Lincoln School Lakes Project, is being evaluated by the New England Division, Corps of Engineers. The site is located on the St. John River in Aroostook County, Maine , approximately 30 miles west of the town of Ft. Kent. The project is primarily designed to generate hydroelectric power, but it is also intended to provide flood control. During November 1974 a study was initiated to apply state-of-the-art remote sensing techniques to the delineation and quantification of surficial geology units to locate construction-material within the headwaters of the St. John River Basin. A photomosaic was prepared from 1966 black and white photography (scale 1 :33,600). Fourteen surficial geology units were delineated in an 1100-square-mile area: alluvial fan, alluvial terrace, esker, floodplain, glacial moraine, kame, kame terrace, outwash, outwash terrace, bedrock, till , till over bedrock, wet outwash and wet till. These units were field checked and the depths estimated utilizing initial boring data, field measurements and seismometer values. The areal extent of each surficial geology unit within a four-mile radius of the three dike sites and a six-mile radius of the main dam site was quantified using a planimetric color densitometer. The volume of construction material was computed based upon these areal determinations and estimated depths. Considerable time was saved using remote sensing techniques compared with conventional ground surveys. The volume estimates obtained from this investigation were compared with the estimates of required construction material computed during the 1967 initial design phase. This comparison showed that the required construction material could be found within the prescribed area around the dam and dike sites. Because transportation of materials is a major cost in dam construction, the reduction in transportation distances determined from this study could result in considerable savings. In addition, the lineations observed on the LANDSAT imagery provided a sound base for analysis of possible tectonism in the Dickey-Lincoln area. It is believed that future movement along the east, northeast , north and N60°W lineations will be negligible.
