Hydrologic region Basin characteristics
Mountain-Windward Mean elevation > 1,200 ft, Windward = primarily western /southern slopes
drained.
Mountain-Leeward Mean elevation >1,200 ft, Leeward = primarily eastern /northern slopes
drained.
Interior-West Mean elevation < 1,200 ft, located south and west of major mountain peaks/
ranges.
Interior-Central Mean elevation <1,200 ft, located between major mountain peaks/ ranges.
Interior-East Mean elevation <1,200 ft, located to the east of Appalachian Mountain
chain.
St. Lawrence Mean elevation <1,200 ft, but north of Appalachian Mountain chain.
Coastal (L.I. Sound) All or most of drainage located within 30 miles of L. I. Sound.

through statistical evaluation of the
grouped discharge data.
The following tasks were performed to
develop and refine regionalized ABF rec-
ommendations within New England:
1. A comprehensive audit of all USGS
gages in New England to determine
unregulated status and basin charac-
teristics;
2. Verification of regulated/ unregulat-
ed stream status with local USGS units;
3. Obtaining August cfsm values from
flow duration data for each gage, based
on mean daily discharge data provid-
ed by the USGS;
4. Identification of key drainage basin
characteristics affecting the cfsm val-
ue ranges;
5. Sorting of streams into hydrologic re-
gions, based on results of (4) above;
6. Calculation of region-specific cfsm
values; and
7. Statistical significance testing of dif-
ferences among regions.
