Description:
Abstract:
Connecticut Dams is a 1:24,000-scale, point feature-based layer that displays the locations of dams in Connecticut that are owned and operated by individuals, businesses, corporations, water and electric utilities, local, state, and federal governments. Each dam is assigned a unique dam number. This information was compiled in 1996 and is based on dam safety information from the Inland Water Resources Division, Connecticut Department of Environmental Protection. The dams were mapped on 7½ Minute U.S. Geological Survey topographic quadrangle maps and digitized at 1:24,000 scale.

Attributes include dam number and name, dam hazard classification, ownership type, town name and number, and major, regional and subregional basin numbers.  This layer does not include all dams in Connecticut and has not been updated since its creation in 1996.   
Purpose:
Connecticut Dams is a 1:24,000 scale spatial data developed for use by the Dam Safety Section of the Inland Water Resources Division, Bureau of Water Protection and Land Reuse, Department of Environmental Protection, State of Connecticut. The Dam Safety Section of the Inland Water Resources Division is charged with the responsibility for administration and enforcement of Connecticut's dam safety laws. The existing statutes require that permits be obtained to construct, repair or alter dams, dikes or similar structures and that existing dams, dikes and similar structures be registered and periodically inspected to assure that their continued operation and use does not constitute a hazard to life, health or property. The dam safety statutes are codified in Section 22a-401 through 22a-411 inclusive of the Connecticut General Statutes. Sections 22a-409-1 and 22a-409-2 of the Regulations of Connecticut State Agencies, have been enacted which govern the registration, classification, and inspection of dams. The Connecticut Dams data depict the locations of dams throughout the state of Connecticut. The information may be dated in some instances and is best used in conjunction with other 1:24,000 scale data such as hydrography, drainage basins, and political boundaries. Attribute information includes a unique dam number and dam hazard classification that rates the potential hazard to life and property as defined by Connecticut State Statute (Section 22a-409-1d), in the event of a dam breach. This information is not intended to be used or printed at map scales greater or more detailed than 1:24,000 scale (1 in. = 2,000 ft.).

Data_Set_Credit:
James Bogar from the Natural Resources Center, DEP originally mapped dam locations at 1:24,000 scale by compiling information primarily available from the Dam Safety program, Inland Water Resources Division, Bureau of Water Protection and Land Reuse, DEP. Tom Nosal and Ann Kuzyk, also from DEP, digitized the maps compiled by James Bogar to create the first statewide digital spatial dataset of Connecticut dams.
Native_Data_Set_Environment:
These data are maintained by the State of Connecticut using ArcGIS software developed by Environmental Systems Research Institute (ESRI) in a Microsoft Windows operating system environment.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The Connecticut Dams layer retains the feature types and information identified by the State of Connecticut, Department of Environmental Protection and obtained from the Dam Safety Program database.  Values are within defined domains, but attributes may not have correct or valid values. Information may be incorrect or out of date. Accuracy check of attribute data is unknown.
Logical_Consistency_Report:
Point features conform to the following topological rules. Points are single part. There are no duplicate points. Points do not overlap. Establishment of logical consistency was performed by the State of Connecticut, Department of Environmental Protection using ESRI ArcGIS software to manually create and control feature topology in originally in ArcInfo coverage format. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
Completeness_Report:
The completeness of the data reflects the feature content of the data sources, which include the dam safety program records and maps on file at the Connecticut Department of Environmental Protection in 1996.  This layer is complete in the sense that it accurately reflects the information available at the time the State of Connecticut, Department of Environmental Protection initially created the Dam layer (1996). However, it is not a complete compilation relative of dams in existence today.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy of this data is no better than the United States National Map Accuracy Standards for 1:24,000 scale maps. According to this standard, not more than 10 percent of the locations 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.  Point features may not be accurately positioned because the locations were interpolated relative to features on USGS 7.5 minute topographic quadrangle maps such as dams, waterbodies, roads, trails, buildings, and elevation contours.

A separate Mylar overlay was prepared and registered to each USGS topographic quadrangle map. At 1:24,000 scale, a point location for each dam located on the quadrangle map was plotted on the Mylar overlay and labeled with the corresponding dam number, the unique identifier, and dam name.

Process_Step:
Process_Description:
Feature digitizing and attribution (digitizing tablet method) - Using ESRI ArcInfo Workstation software, point features were digitized by registering the source map (Mylars) to the digitizing tablet and using the crosshairs of the digitizer's mouse to manually capture the geometry (location) of features drafted on the map. The corners of the USGS 7.5 minute topographic quadrangle maps are used as registration points and are depicted on the source map. The source map was registered to the digitizing tablet by digitizing (entering) the locations of four quadrangle corner registration points shown on the map. ArcInfo software compared the values of the digitized coordinates with the actual (true) values for the quadrangle corner (tic) features. The Root Mean Square (RMS) error generated by the ArcInfo software indicated the amount of error involved in transforming coordinates from the registered map to the digital layer. RMS errors higher than 0.004 were not acceptable and required re-registering the source map by digitizing the tic locations again. With a correct registration, individual features were manually digitized off the source map and assigned their unique DAM_NO values. Feature location and attribute accuracy was visually checked and inspected by symbolizing and labeling features according to attribute value on the computer screen, comparing it to the original source data. Dam name and dam hazard information was also manually entered. Town, major, regional, and subregional basin numbers were assigned using the ArcInfo Identity command in conjunction with town and basin layers.

Subregional Drainage Basin Number - Identifies the Subregional drainage basin the dam is located in. The first digit corresponds to the Major basin number (MBAS_NO) and the first 2 digits represent the Regional basin number (RBAS_NO). All Subregional basins in the same Major and Regional basin have the same first and first 2 digits, respectively. A Subregional drainage basin number ending in "00" defines the main-stem basin for the corresponding Regional drainage basin. For example, Subregional basin 4300 is the main-stem basin for Regional basin 43. These main-stem Subregional basins are usually named after the corresponding Regional basin.
