Listing of Guilford’s Water Resources by Drainage Basin
To provide an overall sense of Guilford’s drainage patterns and hydrology, Guilford’s named water
resources are listed below by the Major Drainage Basin, Regional Drainage Basin, and sub-regional basin in
which they are located. Ultimately, all water draining from Guilford discharges to Long Island Sound and
hence to the Atlantic Ocean.
KEY
• The basin names and numbers used are those assigned by the State of CT DEP. The term,
“unnamed”, is used herein when the local name of a waterbody does not appear on the USGS
map or in local documents and is unknown by the NRIA Committee. (Proper local name for
these, when ascertained, and additional waterbodies can be added to this preliminary listing.)
• For clarification, notation of location or status is included after some water resources
• As source protection is important, water bodies and watercourses that lie within a watershed used
for public water supply are so indicated in parenthesis.
