Connecticut Waterbody Polygon includes the polygon features of a layer named Waterbody. Waterbody is a 1:24,000-scale, polygon and line feature-based layer that includes waterbodies depicted on the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps for the State of Connecticut. This layer only includes features located in Connecticut. Waterbody features include water, dams, aqueducts, canals, ditches, shorelines, and islands. The layer does not include the marsh areas, tidal flats, rocks, shoals, or channels typically shown on USGS 7.5 minute topographic quadrangle maps. The Waterbody layer is comprised of polygon and line features. Polygon features represent areas of water for rivers, streams, brooks, reservoirs, lakes, ponds, bays, coves, and harbors. Polygon features also depict related information such as dams and islands. Line features represent single-line rivers and streams, aqueducts, canals, and ditches. Line features also enclose all polygon features in the form of shorelines, dams, and closure lines separating adjacent water features. The Waterbody layer is based on information from USGS topographic quadrangle maps published between 1969 and 1984 so it does not depict conditions at any one particular point in time. Also, the layer does not reflect recent changes with the course of streams or location of shorelines impacted by natural events or changes in development since the time the USGS 7.5 minute topographic quadrangle maps were published. Attribute information is comprised of codes to identify waterbody features by type, cartographically represent (symbolize) waterbody features on a map, select waterbodies appropriate to display at different map scales, identify individual waterbodies on a map by name, and describe waterbody feature area and length. The names assigned to individual waterbodies are based on information published on the USGS 7.5 minute topographic quadrangle maps or other state and local maps. The Waterbody layer does not include bathymetric, stream gradient, water flow, water quality, or biological habitat information. Derived from the Hydrography layer, the Waterbody layer was originally published in 1999. The 2005 edition includes the same water features published in 1999, however some attribute information has been slightly modified and made easier to use. Also, the 2005 edition corrects previously undetected attribute coding errors.
In 2004, the State of Connecticut Department of Environmental Protection developed automated procedures to systematically maintain feature topology and attribute integrity for a set of related hydrography data maintained by the agency. These layers include Hydrography Master, Hydrography, Waterbody Master, Waterbody, Named Waterbody Master, and Named Waterbody. Automated procedures were developed using ArcInfo Workstation 8.3 software and the Arc Macro Language (AML) as a scripting environment and recorded in an AML file named MAKECOVER.AML for the hydrography category of data for the State of Connecticut, Department of Environmental Protection. The MAKECOVER.AML derives all related hydrography layers from one Hydrography Master layer.

Scale Level. A numeric code that defines scale range levels for features. Scale Level values range from 1 to 6. More features are included in the higher Scale Levels. For example, Scale Level 1 includes only a few major rivers and is intended for a small map of Connecticut. Conversely, Scale Level 6 includes all waterbodies and is intended for more detailed maps displayed at about 1:24,000 scale. Use the Scale Level attribute to specify a definition query that displays a particular set of features, for example SCALELEVEL = 1. Then set the appropriate range of scale (e.g. from 1,000,001 to 3,000,000 scale) for the layer, according to application (mapping) need. Note, Scale Levels are additive so include all Scale Levels below the desired level in a definition query. For example, use the following SQL expression to query for Scale Level 4 features - SCALELEVEL IN (1,2,3,4). Note the use of the IN (INCLUDE) operator in the SQL expression.

Includes linear and polygonal features for rivers, streams, brooks, reservoirs, lakes, ponds, bays, coves, harbors, and other areas of water such as the portion of Long Island Sound in the State of Connecticut published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps. Information encoded about features includes two standard symbology classification schemes, waterbody names, flags for named features, levels for mapping at different scales, feature area in acreage, and feature length in miles. Use the AV_LEGEND or the IMS_LEGEND attribute to symbolize features by basic type (water, dam, stream, shoreline). In the Waterbody layer, the values for AV_LEGEND and IMS_LEGEND are identical for all features. To define a layer that only includes named waterbodies, query line and polygon features for NAMED_COD values greater than 0. To define a layer that only includes named lakes, query the line and polygon features for LAKE_NO and LAKE_NO2 values greater than 0. To define a layer that only includes named streams, query the line and polygon features for STREAM_NO and STREAM_NO2 values greater than 0, and so on. To define a layer that only includes the Connecticut River, query line and polygon features for STREAM_NO and STREAM_NO2 equal to 374. The Stream number for the Connecticut River is 374. Each stream, lake, bay, and harbor can be queried by Id number. To define a layer that includes features typically displayed on a map, exclude all unnecessary features by querying the line and polygon features for AV_LEGEND not equal to "No Show" or IMS_LEGEND not equal to "No Show". Typically, line features with the "No Show" classification enclose Waterbody polygon features that are not outlined on a map. Examples of line features that are not shown include closure lines separating adjacent open water polygons and boundaries defining bay and harbor extents. Define layers of water to display at different map scale ranges by querying line and polygon features on SCALELEVEL values.

The Connecticut Waterbody layer is 1:24,000-scale base map data. It depicts the location of all waterbodies published on the USGS topographic quadrangle maps. It is intended to be used as the portion of a base map that shows waterbodies at 1:24,000 scale. Use this layer with other 1:24,000-scale base map data such as Roads and Trails, Railroads, Airports, and Towns. This layer is derived from the Hydrography layer, which is also published by the State of Connecticut, Department of Environmental Protection. It includes the same waterbodies as the Hydrography layer but without the detailed classification of hydrography feature types that distinguish intermittent streams, intermittent lakes, ditches, manmade shorelines, canals, tidal flats, submerged rocks, marshes, etc. Use this layer to obtain the size (acreage) for all reservoirs, lakes, ponds, and larger (double-line) streams published on the USGS topographic quadrangle maps. This layer may be used as a possible data source for other 1:24,000-scale layers with features that must coincide and line up with stream and shoreline features published on the USGS topographic quadrangle maps. For example, the layer includes a set of connecting line features referred to as Coastline Arcs, which define a shoreline between the Connecticut landmass and Long Island Sound. These Coastline Arc features are commonly used to close polygon features in other 1:24,000-scale layers published by the State of Connecticut, Department of Environmental Protection. For example, Coastline Arcs from the original Hydrography layer define the coastline in the Waterbody, Named Waterbody, Towns, Basins, and Bedrock Geology layers. The Waterbody layer includes information within Connecticut and is derived from the Waterbody Master layer, which includes all similar features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. Note that related hydrography layers such as Waterbody, Waterbody Master, Named Waterbody, Named Waterbody Master, and Hydrography are all ultimately derived from the polygon and line features of the Hydrography Master layer. Typically, layers derived from Hydrography Master define a subset of polygon and line features for either the geographic area encompassed by all USGS topographic quadrangle maps that cover the State of Connecticut (a master layer) or the geographic area of the State of Connecticut, in which case the layer is clipped to the State boundary. The Waterbody layer is not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.).
Hydrography Master is a 1:24,000-scale, polygon and line feature-based layer that includes all hydrography features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. Only polygon and line features that define portions of open water features such as rivers, streams, brooks, reservoirs, lakes, ponds, bays, habors, and coves were used. Other related features such as marsh areas were not incorporated into the Waterbody layer. Hydrography Master is in ArcInfo Coverage format.
Connecticut is a 1:24,000-scale, polygon feature-based layer representing the geographic area encompassed by the State of Connecticut. The State of Connecticut is represented as a single polygon feature. The State boundary on the Connecticut mainland is based on 1:24,000-scale information depicted on the USGS 7.5 minute topographic maps. The State boundary in Long Island Sound is based on latitude and longitude coordinates. Connecticut is in ArcInfo Coverage format
Waterbody is in ArcInfo Coverage format.
Includes all polygon features from the Waterbody layer where the AV_LEGEND attribute was not equal to a value of "No Show" (AV_LEGEND <> "No Show"). This criterion only includes waterbody features and excludes islands and other polygon features that do not represent actual waterbodies. Waterbody_Poly.shp is in Shapefile format.
Waterbody_Poly is in GeoDatabase Feature Class format.
Create 2005 Edition of Waterbody - The automated process for creating (deriving) the Waterbody layer from the Hydrography Master layer is documented in an Arc Macro Language (AML) script named MAKECOVER.AML for the hydrography category of data for the State of Connecticut, Department of Environmental Protection. This AML maintains the feature topology and attribute integrity for the Hydrography Master layer. The MAKECOVER.AML creates the Waterbody layer by extracting and processing the necessary features from the Hydrography Master layer. There are three basic steps in the automated process that creates the Waterbody layer. First, polygon and line features with IMS_LEGEND values equal to "Water" are extracted from the Hydrography Master layer and output to a separate ArcInfo coverage named WATER in which the HYARC_COD, HYPOLY_COD, HYDRO_ARC, and HYDRO_POLY attributes are permanently deleted. Due to the consistent nature of the topology and attribute coding of features in the Hydrography Master layer, line features extracted for the Waterbody layer enclosed all required water polygon features and also formed single line stream features without the need to manually edit features to close polygons or close gaps in line features. Second, polygon and line features were merged (dissolved and unsplit) based on similar attribute values. As a result, previously adjacent and connected features differentiated by HYARC_COD, HYPOLY_COD, HYDRO_ARC, and HYDRO_POLY attribute values were combined into larger features. For example, tidal flat features merged with open water polygon features to form larger water features, manmade shoreline features were combined with natural shoreline features to form basic shoreline features, and intermittent portions of streams were no longer distinguished. Attributes encoding named waterbody information such as STREAM_NO and LAKE_NO were preserved in the output coverage and feature topology was reestablished to enforce the minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 10 feet (dangle length) of the Hydrography Master layer. Finally, the AV_LEGEND attribute values were programmatically reassigned based on the more general IMS_LEGEND attribute values of the Hydrography Master layer. And the SCALELEVEL attribute was programmatically reassigned to ensure consistency with the Hydrography Master layer. The automated process (software program), MAKECOVER.AML that creates this layer was executed in 2005 in order to capture recent corrections and enhancements made to the hydrography data and derive the 2005 Edition of the Waterbody layer from the 2005 Edition of the Hydrography Master layer. The name of the resulting ArcInfo coverage created by this automated process is WATER. Note, this particular run of the MAKECOVER.AML created a copy of the Waterbody coverage that is clipped to the State of Connecticut boundary. The name of the resulting coverage is WATER instead of WATERMASTER, which is the name of the ArcInfo coverage that is not clipped to the State boundary. Prior to 2005, the Waterbody layer in ArcInfo Coverage format that was clipped to the state of Connecticut boundary was named WATERCT.

Export to Shapefile Format - Converted polygon feature data from an ArcInfo coverage named WATER to a Shapefile named Waterbody_Poly.shp. Excluded the AREA, PERIMETER, WATER#, and WATER-ID attributes from the Shapefile because their values are only maintained by ArcInfo software with data that is in ArcInfo Coverage format. Includes all polygon features from Waterbody where the AV_LEGEND attribute was not equal to a value of "No Show" (AV_LEGEND <> "No Show"). This criterion only includes waterbody features and excludes islands and other polygon features that do not represent actual waterbodies.

The layer retains the geometry (shape) of hydrography features identified by the USGS without the original detailed classification (type) of hydrography features established by the USGS. This less detailed classification scheme combines features into fewer categories. These broader categories are encoded in the AV_LEGEND and IMS_LEGEND attributes of the Waterbody layer. The AV_LEGEND and IMS_LEGEND attributes are derived from the HYARC_COD, HYDRO_ARC, HYPOLY_COD, and HYDRO_POLY attributes of the Hydrography layer and are programmatically attributed by the MAKECOVER.AML, which derives the Waterbody layer from the Hydrography layer. As part of creating the Hydrography layer, the COASTP_COD and COASTA_COD attribute values were manually entered, and the COAST_POLY and COAST_ARC attributes that decode these values were populated through table joins to lookup tables. These decode values were not manually entered. The COAST_POLY field is the English language language equivalent of (decodes) the COASTP_COD field for polygon features. The COAST_ARC field is the English language language equivalent of (decodes) the COASTA_COD field for line features. Polygon features were manually selected and populated with STREAM_NO, LAKE_NO, HARBOR_NO, BAY_NO, and SOUND_NO attributes values that identify individually named streams, lakes, harbors, bays and sounds. Named streams represented as a series of single-line features were manually selected and attributed with the corresponding stream number values. The STREAM_NO, STREAM_NO2, LAKE_NO, LAKE_NO2, HARBOR_NO, HARBOR_NO2, BAY_NO, BAY_NO2, SOUND_NO, and SOUND_NO2 for all other line features were attributed through an automated process based on STREAM_NO, LAKE_NO, HARBOR_NO, BAY_NO and SOUND_NO attribute values of the polygon features on the left and right side of line features. For example, shoreline features for all named streams and lakes were attributed with STREAM_NO and LAKE_NO values based on values that were carefully attributed for polygon features that define the waterbody areas. Additional fields that store waterbody names decode these waterbody number values and were populated though table joins to lookup tables. For example, STREAM decodes STREAM_NO. STREAM2 decodes STREAM_NO2. LAKE decodes LAKE_NO. LAKE2 decodes LAKE_NO2. HARBOR decodes HARB0R_NO. HARBOR2 decodes HARBOR_NO2. BAY decodes BAY_NO. BAY2 decodes BAY_N02. SOUND decodes SOUND_NO. SOUND2 decodes SOUND_NO2. The NAMEDP_COD and NAMEDA_COD attribute values are based on the values of STREAM_NO, LAKE_NO, BAY_NO, HARBOR_NO, SOUND_NO, and IMS_LEGEND. NAMED_POLY and NAMED_ARC attributes decode these values and were populated though table joins to lookup tables. The NAMED_POLY field decodes the NAMEDP_COD field for polygon features. The NAMED_ARC field decodes the NAMEDA_COD field for line features. The SCALELEVEL field encodes a cartographic preference defined by the State of Connecticut, Department of Environmental Protection for displaying 1:24,000-scale features at different map scales. There are 6 Scale Levels. Each Scale Level represents a chosen set of waterbodies based on STREAM_NO, LAKE_NO, BAY_NO, HARBOR_NO, and SOUND_NO values. The ACREAGE (area in acres) field was automatically calculated for each polygon feature based on computer generated feature area in square feet. The LENGTH_MI (length in miles) field was automatically calculated for each line feature base on computer generated feature length in feet.
This data complies with United States National Map Accuracy Standards for 1:24,000 scale maps. According to this standard, not more than 10 percent of the points tested are to be in error by more than 1/50 inch (40 feet) measured on the publication scale of a USGS 7.5 minute topographic quadrangle map.
The completeness of the data reflects the USGS National Mapping Division standards for feature content of the data sources, which are the Large Scale (7.5 minute) Digital Line Graph (DLG) files available from the USGS. For Connecticut, the Large Scale DLG files used to create this layer are for the 1:24,000-scale topographic quadrangle maps published between 1969 and 1984. Both the Hydrography and Waterbody layers are complete in the sense that they accurately reflect the contents of the most recently published USGS topographic quadrangle maps available at the time the State of Connecticut, Department of Environmental Protection began creating the layer. More recent quadrangle maps have been published by the USGS since 1984; however, the State of Connecticut did not incorporate this information into the Hydrography, Waterbody or Named Waterbody layer. So compared to the most recent set of topographic quadrangle maps available today, the Hydrography, Waterbody and Named Waterbody layers are incomplete, and substantially incomplete when compared to waterbodies present today. This data is not updated.
Polygon features conform to the following topological rules. Polygons are single part. There are no duplicate polygons. Polygons do not self overlap. Polygons do not overlap other polygons. Polygons are bound by lines. Line features conform to the following topological rules. Lines are single part. There are no duplicate lines. Lines do not self overlap. Lines do not overlap other lines. Lines intersect only at nodes, and nodes anchor the ends of all lines. Lines do not overshoot or undershoot other lines they are supposed to meet and intersect. The tests of logical consistency were performed by the State of Connecticut using ESRI ArcInfo software to maintain feature topology in ArcInfo coverage format. The data is topologically clean. The ArcInfo Clean function was repeatedly used following edits to verify topology and enforce a minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 10 feet (dangle length).
