The Parker River basin, located in Essex County,
contains all or part of nine towns. Altitudes are generally less than 200 ft above sea
level, although some bedrock hills have altitudes of 300 to 400 ft.
Drumlins composed of glacial till are scattered throughout
the area. The following description of the water resources of the Parker River basin is
based on Hydrologic Investigations Atlas 247 (Sammel, 1967). |
