The Middle Devonian Dundee Limestone underlies most of the Lower Peninsula of Michigan. A potentiometric surface constructed of the formation, utilizing pressure data was compared to local and regional structure, permeability trends, specific gravity of the brines, oil accumulations, and surficial topography.

The data were distributed mainly in the central basin area, with information becoming more sparse around the basin margins. This created difficulties in the determination of the extent of control imparted by each of the factors, in flow direction. Surficial topography, on a regional scale, is likely the most influential of the controls, with the Dundee Limestone brines flowing toward outcrops in Lake Michigan. Lake Michigan is acting as a potentiometric low. Lack of data in the eastern portion of the state resulted in a lack of definition of the potentiometric surface in this area; therefore, no relationship could be determined between flow direction and Lake Huron.
