Description: Basin boundary (line) attributes include a drainage divide type attribute (DIVIDE) used to cartographically represent the hierarchical drainage basin system. This divide type attribute is used to assign different line symbology to major, regional, subregional, local, stream reach, and lake impoundment drainage basin divides.
Description: Basin area (polygon) attributes include major, regional, subregional, local, (full) basin number, and feature size in acres and square miles. The full basin number (BASIN_NO) uniquely identifies individual basins and is up to 13 characters in length. There are 7,031 unique basin numbers. Examples include 6000-00-1+*, 4300-00-1+L1, and 6002-00-2-R1. The first digit (column 1) designates the major basin, the first two digits (columns 1-2) designate the regional basin, the first 4 digits (columns 1-4) designate the subregional basin, and the first seven digits (columns 1-7) designate the local basin. Note, there are slightly more basin polygon features (7,076) than unique basin numbers (7,031) primarily because a few water supply watershed boundaries split a basin into two polygon features at the location of a small dam or point of diversion along a stream.

Description: The Local and Subregional Drainage Basin Direction layers are cartographic data products. These point feature must be used with the appropriate drainage basin polygon and line feature data. They must not be depicted on maps as simple point symbols without symbolizing them with arrows that take on the appropriate direction. Theses arrows are meant to indicate where one basin drains into another and are intended aid in visualizing the network of subregional drainage basins. They do not depict the exact location of basin outlets.
Description: Local Drainage Basin Direction is point data used to create directional arrow symbology that depicts the general direction of surface water flow within individual local drainage basins. Particular emphasis is given to directional arrows near the location of local drainage basin outlets. These and similar features along stretches of local drainage basin main stem basins and in coastal basins that drain into Long Island Sound are intended to aid in visualizing the network of local drainage basins in Connecticut. Point features are classified into three types - Outlet Direction, Main Stem Direction and Coastal Direction - and include an attribute that defines arrow direction. Data is compiled at 1:24,000 scale and should only be used for cartographic purposes on maps that also depict Local Drainage Basin Boundaries. Theses arrows are meant to indicate where one basin drains into another basin. They do not depict the exact location of basin outlets.
Description: Subregional Drainage Basin Direction is point data used to create directional arrow symbology that depicts the general direction of surface water flow within individual subregional drainage basins. Particular emphasis is given to directional arrows near the location of subregional drainage basin outlets. These aid in the visualizing the network of subregional drainage basins in Connecticut. Point features include an attribute that defines arrow direction. Data is compiled at 1:80,000 scale. Data should only be used for cartographic purposes on maps that also depict Subregional Drainage Basin Boundaries. They do not depict the exact location of basin outlets.
