NATURAL DRAINAGE BASINSMAJOR, REGIONAL, SUBREGIONAL AND LOCAL
NEW LONDON, CONNECTICUT
SCALE 1:24,000 (1 inch = 2000 feet) when map is printed at original size (48 x 36 in)
LOCAL DRAINAGE BASIN DATA – The drainage basininformation shown on this map is based on the following digitalspatial datasets: Connecticut Local Basin Line and Local Basin Poly.These two datasets were developed by CT DEP and depict major,regional, subregional, and local basin drainage areas and boundariesat 1:24,000-scale. These data depict drainage areas for Connecticutrivers, streams, brooks, lakes, reservoirs and ponds published on1:24,000-scale 7.5 minute topographic quadrangle maps prepared bythe USGS between 1969 and 1984.
SHADED RELIEF ELEVATION DATA – The data used to depictelevation on this map was obtained the University of Connecticut,College of Agriculture and Natural Resources, Center for Land UseEducation and Research (CLEAR). The three-dimensional effect wascreated using a ground elevation and a hill shade dataset theUniversity of Connecticut derived from Connecticut’s 2000 statewideLiDAR dataset.
BASE MAP DATA - Based on data originally from 1:24,000-scaleUSGS 7.5 minute topographic quadrangle maps published between
1969 and 1992. It includes political boundaries, railroads, airports,hydrography, geographic names and geographic places. Streets andstreet names are from Tele Atlas® copyrighted data. Base mapinformation is neither current nor complete.
RELATED INFORMATIONThis map is intended to be printed at its original dimensions in orderto maintain the 1:24,000 scale (1 inch = 2000 feet).
To identify either all upstream basins draining to or all downstreambasins flowing from a particular location, refer to the Gazetteer ofDrainage Basin Areas of Connecticut, Nosal, 1977, CT DEP WaterResources Bulletin 15, for the hydrologic sequence, headwater tooutfall, of drainage basins.MAPS AND DIGITAL DATA - Visit the CT ECO website for thismap and a variety of others in PDF format. Visit the CT DEP websiteto download the digital spatial data shown on this map.
DATA SOURCESFigure 1. Example showing a typical local drainage basin and the subregional, regional, and major drainage basin it is part of.
EXPLANATIONThis map shows the location and identification number of major,regional, subregional, and local drainage basins. It is intended toserve as a municipal guide for drainage basin delineation andidentification. Local basins make up larger subregional, regional, andmajor drainage basin areas and are differentiated by their drainagebasin boundary type and identification numbers. Arrows on the maprepresent general direction of surface water flow within localdrainage basins. Local outlet direction is shown in purple. Mainstem direction is shown in red. Coastal direction is shown in blue.
A 7-digit drainage basin number such as 4302-02 uniquely identifieslocal drainage basin areas shown on this map. Drainage basin areasare numbered sequentially beginning upstream and proceedingdownstream. The identification numbers are hierarchical. The firstdigit (column 1) identifies the major basin, the first two digits(columns 1-2) identify the regional basin, the first 4 digits (columns1-4) identify the subregional basin, and the first seven digits(columns 1-7) identify the local basin. For example, 4, 43, and 4302are the major, regional and subregional basin numbers for local basinnumber 4302-02. As illustrated in the diagram below, this signifiesthat local basin number 4302-02 is part of subregional basin 4302,which is part of regional basin 43, which is part of major basin 4.Drainage basin boundaries shown on this map were manuallydelineated by interpreting the 10 foot contour lines and hydrographyfeatures shown on USGS 1:24,000-scale topographic quadranglemaps. Only limited field checking was conducted to verify thelocation of these basin boundaries. Basin boundaries may not beaccurate in areas that have been diked for flood control, uplandwetland and reservoirs having outlets into two basins, areas where
topographic mapping is not up to date, is inaccurate, or is not detailedenough to adequately define local drainage. Residential andcommercial development, highway construction, and other changesto the landscape may have resulted in local modifications to thenatural drainage pattern since the time these basin boundaries weredelineated.
In order to create a three-dimensional effect, this map usesgradational shades of color rather than contour lines to depictelevation. Areas of low elevation in Connecticut are shown in lightblue. Areas slightly higher in elevation are shown in light yellow,followed by green, orange, red, brown, gray, and white for thehighest elevated areas in Connecticut. The three-dimensional effect isalso achieved by showing shadows cast on high ground as if sunlightis shining from the northwestern direction. As a result, thenorthwestern side of elevated areas is intentionally lighter in colorthan the southeastern side. Relatively flat areas are not shadowed andappear smooth, whereas steeper slopes appear rough with thesoutheastern side appearing darker in color.
