This report presents hydrologic and geologic data collected by the U.S.
Geological Survey during an investigation of water resources in the southwestern
coastal river basins of Connecticut in cooperation with the Connecticut Water
Resources Commission. These basins occupy about 394 square miles in Connecticut
and 46 square miles in New York, including the towns of Greenwich, Stamford,
Darien, New Canaan, Norwalk, Wilton, Westport, Weston, Fairfield, Easton, and
Bridgeport and parts of Danbury, Ridgefield, Redding, Bethel, Newtown, Trumbull,
Monroe, Shelton, and Stratford. A companion interpretive report evaluating the
water resources of the basins will be published as Connecticut Water Resources
Bulletin No. 17. The data on the following pages serve to document and supplement
that report and should be especially useful in planning the development of water
resources at specific localities.
Data were collected as part of this investigation during the period July 1963
through November 1966. Streamflow records from continuous-record gaging stations
in the basins have been published annually along with data from other parts of
the State in a series of U.S. Geological Survey reports entitled "Surface Water
Records of Connecticut." Water-level measurements in wells throughout the State
from 1960 through 1966, including most of those made as part of this investigation,
are published in Connecticut Water Resources Bulletins No. 7 and No. 13. Most
other data collected during this investigation are tabulated on the following pages.
Included are some well records and chemical analyses of water samples collected
prior to July 1963 and not previously published.
The locations of sites at which data were collected are shown on plate A
in the pocket at the back of the report. Data presented, unless otherwise noted,
were collected by U.S. Geological Survey personnel.
