The State of Connecticut, Department of Energy and Environmental Protection is the collector of the data (compiler), the creator and maintainer of the data layer (editor), and producer (publisher) of this information for use. Data compiled at 1:24,000 scale.
This layer includes information that is applicable to a set time period (2012) and is not updated or changed in any way.
A characterization of the data, including its intended use and limitations.
Connecticut 305b Assessed Estuary 2014 is a 1:24,000-scale, polygon feature-based layer that includes estuaries that have been assessed in compliance with Sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody.
This layer is based on information collected and compiled prior to 2014. It represents conditions at a particular point in time and does not represent current conditions. This layer includes only assessed estuaries. It can be used with the 2014 Connecticut 305b Assessed Lakes layer and the 2014 Connecticut 305b Assessed Rivers layer to geographically display attainment and non-attainment for each designated use on assessed waters within Connecticut's boundaries.
Features are polygon locations that represent the locations of assessed estuaries. The sources for these features include the hydrography layer and the water quality classification layer. Attribute information is comprised of a unique identifier (segment Id) for each feature, a description of the waterbody, its location, the assessment cycle (year), the water type, the Long Island Sound basin and zone, whether the feature is an island or a beach, the water quality class, the size in square miles, and the assessment for the following categories: marine aquatic life, recreation, fish consumption, and shellfish. Data is compiled at 1:24,000 scale. This dataset is not updated.
Connecticut 305(b) Assessed Estuary 2012 is 1:24,000-scale data. It depicts the location of assessed estuaries along Long Island Sound, including all Connecticut coastal river estuaries to the extent of salt water influence. Use this layer to show estuary locations and their accompanying use assessment . This layer should be used with the other assessed waterbody layers: Assessed Rivers and Assessed Lakes. To gain a historical perspective, use this layer with the 2006, 2008 and 2010 Assessed Waters layers.
This layer should only be viewed with other 1:24,000-scale map data such as water quality classifications, roads, towns, topographic quadrangles, and digital orthophotos. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)
