![]() They are not only informative, but also quite beautiful, both literally and conceptually. A more recent Connectictut Elevation and Lake Bathymetry CT ECO Guide describes a similar map currently online that includes slightly different Connecticut Contours 2000 data.Have you seen maps covered with swirling, curly lines and wondered what that’s all about? Contour maps are two-dimensional maps or surveys or site plan drawings that are imbued with elevation information through the expression of those lines curving and swirling in spaced proximity to each other. This CT ECO data guide describes a thematic map that is no longer available online from CT ECO. Connect GIS and AutoCAD software to this information online using the Elevation and Bathymetry CT ECO Map Service.Lake Bathymetry data is downloadable from DEEP GIS Data.Instructions for obtaining statewide contour data are available at DEP GIS Data.Download the original contour data files in shapefile format along with other elevation data derived from Connecticut's 2000 statewide LiDAR coverage from Connecticut LiDAR-based Elevation Data.Connecticut Joint Highway Research Council.Connecticut Department of Transportation. ![]() Connecticut Department of Public Safety.University of Connecticut, College of Agriculture and Natural Resources.Connecticut Department of Energy and Environmental Protection.Lake Bathymetry - CT ECO Basic Data Guide.Elevation Contours - CT ECO Basic Data Guide.Map Scale and Accuracy - Varies based on data collection methods.Status - Not presently updated, but may be updated in the future.Due to differences in data capture dates and spatial accuracy, the Lake Bathymetry shoreline and depth contour data may not line up exactly with shoreline features in other hydrography related data from DEP such as Connecticut Hydrography, Connecticut Waterbody, Connecticut Named Waterbody and Connecticut Surface Water Quality Class. There are no distribution restrictions, but the Connecticut Department of Environmental Protection should be cited on any published maps using this dataset. These data were collected and compiled through a variety of methods and no specific scale is recommended. Lake Bathymetry information is only included for the 125 waterbodies listed in the GIS Metadata. Please refer to the Elevation Contours CT ECO Basic Data Guide for an explanation of this use limitation. The Elevation Contour information is known to be incorrect in some areas. The Lake Bathymetry information was compiled to depict water depth and map the bottom of selected water bodies open to the public for fishing in Connecticut. Additionally, the closer contour lines are to one another the steeper the slope. Commonly known as the rule of V's, the V in the contour line always points upstream. Contour lines are often V shaped where they cross a stream. The direction of a stream can be determined by taking note of the shape of contour lines as they cross a stream. From these contours a general sense of the lie of the land, terrain or relief can be determined. The Elevation Contour information denotes elevation above sea level. Gerrish, Connecticut Department of Environmental Protection Bulletin 35, 2002, SBN 0-94. This information was used to publish bathymetric maps in the A Fisheries Guide to Lakes and Ponds of Connecticut, Robert P. A list of the waterbodies included in this layer can be viewed in the GIS Metadata for Lake Bathymetry. Data is compiled at a variety of scales and resolutions, depending on the collection method used for a particular waterbody. This information was collected and compiled by the State of Connecticut, Department of Environmental Protection over a period of time using a variety of different techniques and equipment including manual depth soundings, use of an electronic depth sounder, use of a GPS receiver to locate the boat, and digitizing previously published bathymetry maps. It includes depth contours, also called bathymetric contours, that define lines of equal water depth in feet. Lake Bathymetry describes the water depth for selected reservoirs, lakes, ponds, and coves in Connecticut. These data are a Beta product intended for research and demonstration purposes. This information was derived from Connecticut’s 2000 statewide LiDAR dataset by the University of Connecticut, College of Agriculture and Natural Resources, Department of Natural Resources and the Environment. Note, the contour interval shown depends on the current scale of the map with smaller intervals displayed when zoomed in at larger and more detailed scales. Includes Elevation Contour information for Connecticut and Lake Bathymetry (depth contours) for selected lakes and water courses.Įlevation Contours includes 2, 10, 20, 50, and 100 ft elevation contour lines for Connecticut.
