The purpose of the�Natural Resources Atlas�is to provide geographic information about environmental features and sites that the Vermont Agency of Natural Resources manages, monitors, permits, or regulates. In addition to standard map navigation tools, this site allows you to link from sites to documents where available, generate reports, export search results, import data, search, measure, mark-up, query map features, and print PDF maps.

This map is a rendition of VTANR's Natural Resources Atlas. This application gives our users the ability to take the Atlas data with them, wherever there is network connectivity. Although not as rich with features as the Natural Resources Atlas website, this application provides a quick glance of Vermont's Natural Resources Data wherever you are, providing a great resource for field scientists, planners, consultants, etc. that need to know what's at their current location.

For a thorough discussion of the purpose, design and management of the Vermont River Corridors dataset, please see the "Vermont DEC Flood Hazard Area and River Corridor Protection Procedures December 5, 2014" http://www.vtwaterquality.org/rivers/docs/FHARCP_12.5.14.pdf . River corridors encompass an area around and adjacent to the present channel where fluvial erosion, channel evolution and down-valley meander migration are most likely to occur. River corridor widths are calculated to represent the narrowest band of valley bottom and riparian land necessary to accommodate the least erosive channel and floodplain geometry (i.e. equilibrium conditions) that would be created and maintained naturally within a given valley setting. River corridors are developed to facilitate ANR’s responsibilities in providing municipalities, regional planning commissions, and Act 250 District Commissions with technical assistance and information concerning river sensitivity and fluvial erosion hazards. Vermont river corridors include areas where active, potentially hazardous river erosion and deposition process have occurred or are likely to occur. These delineations do NOT indicate that areas outside river corridors, particularly those immediately abutting the river or river corridor are free from fluvial erosion hazards.This dataset is part of the “applicable maps” used in conjunction with other best available stream geomorphic data to implement both the Flood Hazard Area and River Corridor “Rule” and “Protection Procedure.” The data will be updated over time as described in the Procedure. The date of the version posted on the Vermont Natural Resource Atlas indicates the most recent update. Users should cite the Creation Date for the version. Data processing was done using ArcGIS 10.x, Spatial Analyst, and Arc Hydro Tools 2.0. Source and digitized data included VT Meander Centerlines (MCLs), VT Reach Break points, VT Hydrography streams, VT 10-meter DEM, VTHYDRODEM, HUC 8 Basins, VT Roads and Railroads, field-verified Valley Walls and Stream Geomorphic Assessment datasets. This 2019 version is a hybrid of Phase I and II levels of detail. River Corridor polygons are divided by subwatershed breaks and by SGA reach/segment breaks. Attributes include SGAT ID, Stream Name, Drainage Area in square miles, Bankfull width in feet, Channel Multiplier, DMS Channel Multiplier, DMS Channel Width, Erosion Power/Risk and Deposition Power/Risk. Major derived datasets include raster and vector valley walls, catchments per stream reach, variable-width MCL buffers, and the final River Corridor. A Frequently-Asked Questions page is available at: http://floodready.vermont.gov/rcfaqThis package also includes streams that have a drainage area between .25 and 2 square miles. Streams were mapped by filtering drainage areas from the VHD accumulation grids. They were then extracted from the grid and vectorized. Linework is for reference only, as it does not match the VHD perfectly. Small streams are given a simple 50-foot setback from top of bank in lieu of a mapped River Corridor.

Mapped Pools include a unique pool ID, geoLocation in decimal latitude and longitude, and a pool statusvalue indicating the pool’s presumed or verified status (Confirmed, Probable, Potential, Duplicate,Eliminated). In addition, Mapped Pools include dates of interaction with the data for each pool, the peopleresponsible for that interaction - observer and VPAtlas user, the town where the pool is located, estimatedlocation uncertainty, and the method used to map the pool (Known, Aerial Photo Interpretation, Field Visit).Information about the landowner may also be included, along with the observer’s comments about thepool’s status and location.

The shaded circles on this map delineate Vermont’s EAB Infested Area. Each infested area represents a 10-mile radius around a known EAB infestation. While symptoms may not be obvious, it is likely that EAB is present in much of this area.  For each infested area, the relative EAB infestation severity is represented along a color spectrum. A yellow infested area indicates a less severe infestation.  Lower severity infested areas are not yet showing infestation symptoms or decline but EAB has been found. A red infested area indicates a more severe infestation, multiple detections of EAB in a close area, or both. Higher severity infested areas are exhibiting visible infestation symptoms or tree death. The severity of infestation in each infested area will be assessed annually by staff from the Department of Forests, Parks, and Recreation and the map will be adjusted as needed.  EAB is not necessarily present throughout any given infested area, and it can rarely be found at low population densities. Often, by the time the insect is detected, it has already dispersed. Therefore, this map indicates the likelihood of EAB based on where it has actually been observed. Applying Slow the Spread recommendations reduces the risk of spreading EAB and provides time to conduct management activities.  This map will be updated as new locations of EAB are detected in and near Vermont.  The EAB Infested Area Map location is also available on the ANR Atlas. The “EAB Infested Area” layer is under the Forests, Parks, and Recreation tab in the Atlas layers. This mapping function allows you to look at the infested area in conjunction with other layers like parcels or roads, disposal sites, and composting facilities, as well as seeing the details associated with each infestation including the year that EAB was detected, infestation severity, and the last time the site was evaluated.

The 2011 Bedrock Geologic Map of Vermont (1:100,000 scale) was created to integrate detailed (1:12,000- to 1:24,000-scale) modern mapping with the theory of plate tectonics to provide a framework for geologic, tectonic, economic, hydrogeologic, and environmental characterization of the bedrock of Vermont. It supersedes the 1961 bedrock geologic map which was produced at a scale of 1:250,000 (Doll and others, 1961).Please see the metadata and readme files at the publication website:https://pubs.usgs.gov/sim/3184/

The Vermont Flood Ready Atlas is an online-map tool that can help you identify critical facilities, transportation services and buildings in your community that are at risk of damage from flooding. The Atlas can also help you identify local watersheds and the extent of natural flood protection provided by forests, wetlands, floodplains and river corridors.The Vermont Flood Ready Atlas allows you to easily find data about your community and watershed. Nonetheless, you may want to refer to theTips and Tricks section below to get your bearings. If you have any questions, ideas or problems – let us know! Thank you.
