One of a set of three 1:24,000-scale datalayers that represent the classifications of shellfish growing waters for the State of Connecticut shoreline towns. This datalayer is composed of polygon features. The shellfishing areas are delineated and classified by the DA/BA, which is the state shellfish control authority in Connecticut. The Connecticut Department of Environmental Protection (DEP) applied information from the DA/BA to the hydrography data to create digital data of shellfish area classifications. DA/BA reassesses pollution sources and shellfish growing areas annually. The digital data is current to that effective date or last amended date recorded on the assessment date list (see supplemental information). This data is subject to change and the DA/BA may have more recent information for some areas. DEP cooperated with the DA/BA to publish the DA/BA Shellfish Area Classifications data. More recent shellfish classification information may now be available from DA/BA since the time this information was originally published in 2007. The three classification datalayers are feature based. Waterbodies, such as rivers and lakes and ponds, that appear as area features in the hydrography datalayer are classified in the Shellfish Area polygon shapefile. Smaller water bodies, such as streams and creeks, that appear as line features in the hydrography datalayer are classified in the Shellfish Area line shapefile. A separate point shapefile contains the marinas that are classified by DA/BA. Contact DA/BA or local health departments for additional information regarding the classification of marinas and anchorage areas. Three additional datalayers add to the classification picture. Markers, such as buoys, demarcation signs and piers, are referred to in DA/BA text describing the shellfish area classifications. The town boundary lines as depicted on DA/BA oyster/shellfish ground charts extend to the Connecticut/New York mid-Long Island Sound boundary line. The jurisdiction line on the charts indicates the boundary between state and town jurisdictional control over shellfish grounds. The jurisdiction line is separate from the shellfishing area classifications

This data is a graphic representation of NJ coastal waters classified according to regulations of shellfish harvest. Waters are classified in one of five categories: Prohibited - harvest not allowed under any conditions. Special Restricted - harvest allowed with a special permit requiring further purification of the shellfish before sale. Seasonal (Nov - Apr) - and Seasonal (Jan - Apr) - where harvest is permitted only during certain seasons of the year. The final category is Approved - harvest permitted under any conditions. Classification of the waters is based on the National Shellfish Sanitation Program. As specified in this program, classifications are based on three components: 1) Regular monitoring of water quality 2) Field surveys of shoreline conditions 3) Study of water currents and flows (hydrography). These functions are performed by New Jersey's Bureau of Marine Water Monitoring which monitors about 2,500 locations a minimum of five times a year. Please note: Shellfish water classifications in this theme may be temporarily superseded by an emergency closure order. The Department may suspend harvest in areas impacted by an intermittent pollution episode or emergency condition when the event has or may have a deleterious impact on public health. Public notice will be provided of any emergency closures. However, if there are any questions about the suitability of a shellfish growing are for harvest, please contact the Bureau of Marine Water Monitoring at (609) 748-2000.

To protect public health from contaminated shellfish, primarily due to harmful pathogens, state agencies regulate where shellfish can and cannot be harvested for direct human consumption. The status of shellfishing areas serves as an indicator of public health conditions in the Bay. This vector dataset contains shellfishing area classifications for 2020 in the Narragansett Bay, Little Narragansett Bay, and Southwest Coastal ponds. Using data from the Massachusetts Division of Marine Fisheries (MADMF), the Rhode Island Department of Environmental Management (RIDEM), and the Connecticut Department of Agriculture, Bureau of Aquaculture (CTDABA), The Narragansett Bay Estuary Program defined three categories derived from the shellfish growing area classification systems used by Massachusetts and Rhode Island. In “Approved” areas, shellfish harvesting is allowed for direct human consumption all year round (some exceptions may apply). “Conditionally Approved” areas allow shellfish harvesting for direct human consumption with some restrictions, depending on each state’s shellfish program criteria. In “Prohibited” areas, shellfish harvesting is not allowed for direct human consumption. This dataset is intended for use in general planning, GIS analysis, and graphic display at watershed and subwatershed scales. For more information, please contact msorlien@nbep.org.

See full Data Guide here. Surface Water Quality Classifications Set: This dataset is a line and a polygon feature-based layer compiled at 1:24,000 scale that includes water quality classification information for surface waters for all areas of the State of Connecticut. The Surface Water Quality Classifications and the Ground Water Quality Classifications are usually presented together as a depiction of water quality classifications in Connecticut. Water Quality Classifications, based on the adopted Water Quality Standards, establish designated uses for surface and ground waters and identify the criteria necessary to support those uses. This edition of the Surface Water Quality Classifications is based on the Water Quality Standards adopted on February 25, 2011. Surface Water means the waters of Long Island Sound, its harbors, embayments, tidal wetlands and creeks; rivers and streams, brooks, waterways, lakes, ponds, marshes, swamps, bogs, federal jurisdictional wetlands, and other natural or artificial, public or private, vernal or intermittent bodies of water, excluding groundwater. The surface waters includes the coastal waters as defined by Section 22a-93 of the Connecticut General Statutes and means those waters of Long Island Sound and its harbors, embayments, tidal rivers, streams and creeks, which contain a salinity concentration of at least five hundred parts per million under the low flow stream conditions as established by the Commissioner of the Department of Environmental Protection. The Surface Water Quality Classes are AA, A, B, SA and SB. All surface waters not otherwise classified are considered as Class A if they are in Class GA Ground Water Quality Classifications areas. Class AA designated uses are: existing or proposed drinking water, fish and wildlife habitat, recreational use (maybe restricted), agricultural and industrial supply. Class A designated uses are: potential drinking water, fish and wildlife habitat, recreational use, agricultural and industrial supply. Class B designated uses are: fish and wildlife habitat, recreational use, agricultural and industrial supply and other legitimate uses including navigation. Class B* surface water is a subset of Class B waters and is identical in all ways to the designated uses, criteria and standards for Class B waters except for the restriction on direct discharges. Coastal water and marine classifications are SA and SB. Class SA designated uses are: marine fish, shellfish and wildlife habitat, shellfish harvesting for direct human consumption, recreation and other legitimate uses including navigation. Class SB designated uses are: marine fish, shellfish and wildlife habitat, shellfish harvesting for transfer to approved areas for purification prior to human consumption, recreation and other legitimate uses including navigation. There are three elements that make up the Water Quality Standards which is an important element in Connecticut's clean water program. The first of these is the Standards themselves. The Standards set an overall policy for management of water quality in accordance with the directive of Section 22a-426 of the Connecticut General Statutes. The policies can be simply summarized by saying that the Department of Environmental Protection shall: Protect surface and ground waters from degradation, Segregate waters used for drinking from those that play a role in waste assimilation, Restore surface waters that have been used for waste assimilation to conditions suitable for fishing and swimming, Restore degraded ground water to protect existing and designated uses, Provide a framework for establishing priorities for pollution abatement and State funding for clean up, Adopt standards that promote the State's economy in harmony with the environment. The second element is the Criteria, the descriptive and numerical standards th

“Wet storage” means the temporary storage of shellstock from shellfish growing areas in the approved classification or in the open status of the conditionally approved classification. Shellstock can be stored in containers or floats in natural bodies of water or in tanks containing natural or synthetic seawater.For more information, see Chapter 15 of DMR rule.

The Maine Department of Marine Resources (DMR) classifies shellfish growing areas for harvest suitability following the guidelines in the National Shellfish Sanitation Program Model Ordinance. Shellfish growing areas are administrative segments of the Maine coast that represent large bays, estuaries, and islands. Each of the 47 commercially harvested growing areas is assigned a classification based on the results of a sanitary survey, a three-fold process consisting of: a shoreline survey to identify pollution sources in the growing area, surface water sampling to determine fecal coliform bacteria levels in marine water, and an analysis of how weather, tides, currents, and other factors may affect the distribution of pollutants in the area. A growing area may be classified as Approved, Conditionally Approved, Restricted, Conditionally Restricted, or Prohibited.Once classified, all shellfish growing areas are regularly monitored. Marine surface water samples are collected throughout the year. Shoreline surveys are conducted less frequently, but each year some portion of the Maine coast is surveyed. During shoreline surveys, all actual and potential pollution sources that may impact water quality in the growing area are evaluated. The data from continuous water sampling and shoreline surveys are used to ensure that shellfish growing areas continue to meet the standards associated with their classification, to modify classifications when needed, and to notify the responsible agencies about any pollution sources that are identified.

This geodatabase contains data from the 2017 State of Narragansett Bay and Its Watershed Technical Report (nbep.org), Chapter 24: "Shellfishing Areas." Shellfishing area classifications for 1995, 2000, 2005, 2010, 2015 in the Narragansett Bay and Southwest Coastal Ponds were prepared using data from the Massachusetts Division of Marine Fisheries (MADMF) and the Rhode Island Department of Environmental Management (RIDEM). The Narragansett Bay Estuary Program defined three categories derived from the shellfish growing area classification systems used by Massachusetts and Rhode Island (Approved, Conditionally Approved, and Prohibited). Summary tables catalog the extent (area in acres; percent) of estuarine shellfishing classifications for 1995, 2000, 2005, 2010, and 2015 for the full study areas and for the major regions of the bay.

Shellfishing area classifications for 1995, 2000, 2005, 2010, 2015, and 2020 in the Narragansett Bay, Southwest Coastal Ponds, and Little Narragansett Bay were analyzed using data from the Massachusetts Division of Marine Fisheries (MADMF), the Rhode Island Department of Environmental Management (RIDEM), and Connecticut Department of Agriculture, Bureau of Agriculture (CTDABA). The Narragansett Bay Estuary Program defined three categories derived from the shellfish growing area classification systems used by Massachusetts, Connecticut, and Rhode Island. In “Approved” areas, shellfish harvesting is allowed for direct human consumption all year round (some exceptions may apply). “Conditionally Approved” areas allow shellfish harvesting for direct human consumption with some restrictions, depending on each state’s shellfish program criteria. In “Prohibited” areas, shellfish harvesting is not allowed for direct human consumption.

The Department of Marine Resources (DMR) Bureau of Public Health collects surface water grab samples at approximately 1,200 water quality monitoring stations along the Maine coast year-round. Samples are processed in the lab via membrane filtration and enumerated for fecal coliform bacteria. Fecal coliform results are reported as the number of colony forming units (individual bacterium capable of forming colonies) per 100mL of water. DMR scientists analyze data from each station and calculate annual summary statistics using at least 30 of the most recent samples collected under a systematic-random sampling strategy. These values, along with sanitary surveys of the area, help determine whether the water quality is acceptable for harvesting molluscan shellfish.DMR's Shellfish Growing Area Classification Program classifies shellfish areas as Approved, Conditionally Approved, Restricted, Conditionally Restricted or Prohibited using standards set by the National Shellfish Sanitation Program (NSSP), a federal/state cooperative program that sets the requirements for all states involved in interstate shellfish harvest and sale. For more information about the classification of shellfish flats, visit https://www.maine.gov/dmr/fisheries/shellfish/shellfish-growing-area-classification.All classifications are based on two factors: the results of a shoreline survey which looks for the presence of pollution sources, and fecal coliform monitoring results. Two statistical values are calculated from the most recent 30 fecal coliform scores: the geometric mean (geomean) and the 90th percentile (P90). The standards for Approved classification are 14 CFU or less (geomean) and 31 CFU or less (P90). The standards for Restricted are 88 CFU or less (geomean) and 163 CFU or less (P90). The standards for Prohibited are greater than 88 CFU (geomean) and greater than 163 CFU (P90).End of year 2022 P90 data for all Maine active and investigative water quality stations based on the most recent 30 samples. Conditional Area stations are based on last 30 samples in the open status. Data projection is NAD 1983 UTM Zone 19N.

The Maine Department of Marine Resources (DMR) classifies shellfish growing areas for harvest suitability based on the results of a shoreline survey and fecal coliform bacteria monitoring in coastal waters. During a shoreline survey, DMR staff document the presence of wastewater pollution sources along Maine's coast. Based on this information, each growing area is classified as either Approved, Conditionally Approved, Restricted, Conditionally Restricted or Prohibited following standards set by the National Shellfish Sanitation Program, a federal/state cooperative program created for the sanitary control of shellfish produced and sold for human consumption.
