Brief Description:
This is a 1:24,000-scale datalayer of named streams in Connecticut. It includes
two Shapefiles with line and polygon features. Both Shapefiles should be used
together. The polygon shapefile fills in open water streams such as the Connecticut
River as well as Long Island Sound. The line shapefile includes single line
streams as well as the shoreline for the larger streams represented as polygons
in the other shapefile. Each single line stream and polygon is assigned a stream
number. This datalayer is based on the lakes, ponds, streams, and rivers that
appear on the U.S. Geological Survey (USGS) 7½ minute topographic quadrangle
maps that cover the State of Connecticut. The stream boundary information is
derived from the hydrography datalayer, which is based on the USGS Digital Line
Graph Files (DLG) for the 1:24,000 scale Connecticut quadrangle maps published
between 1969 and 1984.
This datalayer does not include all of the streams on the USGS topgraphic 7½
minute quadrangle maps. It is intended to be used with the named lakes and,
optionally, hydrography marsh datalayers for a simple representation of waterbodies.
To represent all waterbodies on the USGS 7½ minute topographic quadrangle
maps, use the hydrography datalayer.
