AbstractThe Fredericton sedimentary sub-basin forms the westernmost section of the St. Lawrence Plains. The sediments of the sub-basin range in age from Pennsylvanian to Kississippian. The principal structural feature is the Fredericton Graben, a down-faulted black that occupies the northwest quadrant of the basin. The sub-basin displays no large identifiable aquifers. On a large scale, however, the series of sediments that are of limited areal extent display hydraulic continuity. Within the sub-basin groundwater flow occurs in two major directions, northeastwards and eastwards. Known water yields in the upper 200 m vary from 0.076 L/s to 38.0 L/s. Potential aquifers lie at depth, likely in Lower Pennsylvanian and Upper Kississippian sediments. Flows are expected to be in the range 38 to 76 L/s.
