13 A series of 1:250,000 scale maps showing well yield, well depth, and depth to
14 bedrock for a large number of bedrock wells inventoried by the Maine Geological
15 Survey in the mid-to late 1970's comprises this data set. Some series also
16 show bedrock topography and potentiometric surface. Geographic coverage is
17 restricted to Southern Maine.
