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 wheretopographic mapping is not up to date, is inaccurate, or is notdetailed enough to adequately define local drainage. Residential and

commercial 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.The elevation contour lines shown on this map are more accuratethan those used to originally delineate the drainage basin boundariesso, in certain areas, the basin boundaries may not exactly reflect theshape of the land surface depicted by the contour lines shown on thismap. These contour lines are based on information from a statewidecollection of ground elevation LiDAR data for the year 2000. Thisinformation is only suitable for general planning and informationalpurposes. It is not intended for exact determinations of elevationwhere a survey is normally required, or for detailed engineering,building, or design purposes. With this information, a general senseof the lay of the land can be ascertained. Gentle slopes arecharacterized by widely spaced contour lines, while steep slopes arerepresented by closely spaced contour lines. Contour lines that crossstreams flowing through valleys of noticeable relief will form a V-shaped deflection with the apex of the V pointing upstream.However, river and stream features and watershed delineations thatare based on USGS topographic quadrangle maps at 1:24,000 scalemay not align exactly with the terrain of stream valleys and elevationof hills and ridges depicted by these contour lines.Note: The major, regional and subregional drainage basin boundariesshown on this map are the same as those published on the 1:125,000-scale state map entitled Natural Drainage Basins in Connecticut,McElroy, 1981. The basin boundaries shown on this town map weredigitized from the 1:24,000-scale compilation sheets used to publishthe state map of Natural Drainage Basins in Connecticut, 1981.

DATA SOURCESLOCAL 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.ELEVATION CONTOUR DATA – The elevation contour lineinformation shown on this map was derived from a statewide 10-footDigital Elevation Model (DEM) surface. The DEM was based on theConnecticut LiDAR dataset for 2000, which captured groundelevation every 20 feet at a horizontal accuracy of approximately 3feet on the ground. For unknown reasons, data was collectedunevenly in some areas, which resulted in data gaps. The Universityof Connecticut, Center for Land Use Education and Research(CLEAR) created the DEM and edited it to fill in data gaps withinformation from contour lines on USGS 1:24,000-scale topographicmaps. However, some inaccuracies remain and the data should beused within the known limitations of the source data.
