This data set provides the water quality classifications of New York State's lakes, rivers, streams and ponds, collectively referred to as water bodies. All water bodies in the state are provided a water quality classification based on existing, or expected best usage, of each water body or water body segment. Under New York State's Environmental Conservation Law (ECL), Title 5 of Article 15, certain waters of the state are protected on the basis of their classification. Streams and small water bodies located in the course of a stream that are designated as C (T) or higher (i.e., C (TS), B, or A) are collectively referred to as "protected streams.For more information see https://dec.ny.gov/environmental-protection/water/water-quality/standards-classifications1. The public should not make any business decisions and/or financial commitments based on the water quality classification data until they have secured the necessary permissions from the Department of Environmental Conservation. 2. The NYSDEC asks to be credited in derived products. 3. Secondary distribution of the data is not allowed. 4. Any documentation provided is an integral part of the data set. Failure to use the documentation in conjunction with the digital data constitutes a misuse of the data. 5.

Line data locating and differentiating transportation corridors on state DEC lands.

To provide a faithful representation of official New York State regulatory freshwater wetlands maps for GIS resource analysis at scales equal to the 1 to 24,000 scale of original mapping or smaller scales (e.g., 1 to 100,000 scale).Regulatory maps consist of mylar versions of New York State Department of Transportation 1 to 24,000 planimetric maps on which wetland boundaries and wetland identification codes are drawn. Planimetric maps are generally congruent with and have the same quad names as United States Geological Survey 7.5 minute topographic maps; a few of the Department of Transportation quads have extended borders. Regulatory wetland maps are prepared by NYSDEC and filed as required by the Freshwater Wetlands Act (Article 24 of the Environmental Conservation Law). Associated with the maps are Classification Sheets that list the Wetlands Identification Code, the municipality in which the wetland occurs and the regulatory class of each wetland. Preparation and filing dates vary by county. As amendments to the official maps occur, the coverages are updated so that the GIS information reflects the regulatory maps currently in use. Archive copies of county coverages with previous versions of the official maps are kept. An important feature of the offical maps is that the lines indicate only "the approximate location of the actual boundaries of the wetlands" (ECL Section 24-0301(3)). For a final determination of the actual location of a wetland it is necessary to contact the NYSDEC office for the region in which the wetland occurs.

In 2016 NYC Parks contracted with the UVM Spatial Analysis Lab to use modern remote sensing and object-based image analysis to create a new wetlands map for New York City. Data inputs include Light Detection and Ranging Data, State and Federal Wetland Inventories, soils, and field data. Because the map was conservative in its wetlands predictions, NYC Parks staff improved the map through a series of desktop and field verification efforts. From June to November 2020, NYC Parks staff field verified the majority of wetlands on NYC Parks' property. The map will be opportunistically updated depending on available field information and delineations. Another dedicated field verification effort has not been planned. As of June 2021, no subsequent updates to the data are scheduled. Original field names were updated to field names that are easier to understand. This dataset was developed to increase awareness regarding the location and extent of wetlands to promote restoration and conservation in New York City. This map does not supersede U.S. Fish and Wildlife Service National Wetlands Inventory (NWI) and New York State Department of Environmental Conservation (NYSDEC) wetlands maps and has no jurisdictional authority. It should be used alongside NWI and NYSDEC datasets as a resource for identifying likely locations of wetlands in New York City. Mapped features vary in the confidence of their verification status, ranging from "Unverified" (meaning the feature exists in its original remotely mapped form and has not been ground truthed) to "Verified - Wetland Delineation" (meaning the boundaries and type of wetland have been verified during an official wetland delineation). Because of the rapid nature of the protocol and the scale of data collection, this product is not a subsitute for on-site investigations and field delineations. The dataset also includes broad classifications for each wetland type, e.g. estuarine, emergent wetland, forested wetland, shrub/scrub wetland, or water. Cowardin classifcations were not used given rapid verfication methods. The accuracy of the wetlands map has improved over time as a result of the verification process. Fields were added over time as necessitated by the workflow and values were updated with information, either from the field verifications, delineation reports, or desktop analysis.

Published: August 2022A vector polygon GIS file of NYSDEC regional boundaries to shorelines in New York State. The file was originally a compilation of U.S. Geological Survey 1:100,000-scale digital vector files and NYS Department of Transportation 1:24,000-scale and 1:75,000-scale digital vector files. Boundaries were revised to 1:24,000-scale positional accuracy and selectively updated based on court decisions. Currently, boundary changes are made as needed based on authoritative sources.

Geospatial data about Erie County, New York DEC Wetlands. Export to CAD, GIS, PDF, CSV and access via API.

This dataset contains only those wetlands regulated by the New York State Freshwater Wetlands Act. It does not necessarily contain wetlands regulated by other jurisdictions or unregulated wetlands, nor does it contain tidal wetlands regulated by New York State under the Tidal Wetlands Act (ECL Article 25).This dataset was originally composed of a set of ARC/INFO coverages containing both polygonal and linear features. The Coverages are based on official New York State Freshwater Wetlands Maps as described in Article 24-0301 of the Environmental Conservation Law. Coverages are not, however, a legal substitute for the official maps. Coverages are available on a county basis for all areas of New York State outside the Adirondack Park. The coverage for Columbia County incorporates proposed amendments which became the official regulatory wetland boundaries as of November 30, 2011 and March 5, 2013.An important feature of the official maps is that the lines indicate only "the approximate location of the actual boundaries of the wetlands" (ECL Section 24-0301(3)). For a final determination of the actual location of a wetland it is necessary to contact the NYSDEC office for the region in which the wetland occurs.Columbia County is in Region 4.

The New York State Department of Environmental Conservation (DEC) maintains a network of Public Fishing Right parking areas along trout streams in New York. This dataset represents the locations and information about those parking areas. Links to PDF maps of the actual Public Fishing Rights along the streams are available as part of the data set.

This data displays the locations of top rivers, streams, lakes and ponds for fishing in New York State, as determined by fisheries biologists working for the New York State Department of Environmental Conservation. These biologists recommended popular rivers, streams, lakes and ponds based on quality of fishing and public access. Data set was created based on their recommendations, and each point was placed at the center of the recommended lakes. Although every effort has been made to ensure the accuracy of information, errors may be reflected in the data supplied.

Data set of the Potential Places of Refuge identified in Alaska Subarea Response Plans. Potential Places of Refuge are pre-identified sites that may aid decision-makers in responding to vessels in distress. These plans are tailored to protect sensitive areas from impacts from possible spills and to save time during the critical first few hours of a vessel response.
