Geophysical survey underway at Tappan Lake
Many people have noticed some activity at Tappan lake and are wondering what’s happening. A company called TGS Geophysical is conducting a geophysical survey of 689 square miles of land. Much of that land falls within the MWCD boundary so in order to have a complete data set, the MWCD has allowed TGS to survey land at Tappan, Clendening, and Seneca Lakes. The data collected will be used to create an image of geologic formations under the MWCD and adjacent property to identify thickness and slope of rock formations, as well as any irregularities in those formations. In order to collect the necessary data, geophones are placed on land, as well as on buoys on the lake, to record vibrations. The temporary survey stakes currently visible on the drained lake bottom at Tappan Lake mark the point where geophones will be placed this winter. A more completed description of the process can be found here.
