State of Connecticut, Department of Energy and Environmental Protection (data compiler, editor and publisher) 2016 vector digital data Hartford, Connecticut, USA State of Connecticut, Department of Energy and Environmental Protection 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 (2016) and is not updated or changed in any way. http://www.ct.gov/deep Connecticut 305b Assessed Estuary 2016 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 2016. 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 2016 Connecticut 305b Assessed Lakes layer and the 2016 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 2016 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 other 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.)

SHAPE.area SHAPE.len Includes assessed estuary features to include size of feature in acres and square miles, the reporting year (assessment year), unique identification, name and location of feature, water quality class goal, type of waterbody, Long Island Sound basin name and zone, whether or not the feature is an island or beach, and categories assessed: marine aquatic life viability, recreation, fish consumption, and shellfish harvesting. Use the ID305B field to uniquely identify features. The Name attribute decodes ID305B. Use either the Name attribute or the ID305B attribute to label features on a map. To define a layer that only includes a certain assessment of a feature type, query the features for a specific attribute (e.g. Recreation) equal to a specific value (e.g. Not Supporting). This will display only those features where the Recreation use is Not Supporting. State of Connecticut, Department of Energy and Environmental Protection mailing and physical address
