This map series takes a wider view of the potential impacts of hydropower on water and wildlife, looking at the entire state of New York. Like the community view maps of the Sawkill River watershed, these maps examine the interaction of biological barriers, such as dams and culverts, with areas of groundwater vulnerability, surface water, fish passage, and protected lands. The intention of these maps is to put the impact of hydropower into perspective at the landscape scale. If you zoom in to a location on the map, you can toggle between the tabs on the map to see various information pertaining to each issue.

These state-wide maps use web-services exclusively rather than relying on locally hosted data layers. Web services used here reference data located on an ArcGIS server site that is made available to the public through Esri’s cloud-based mapping platform – ArcGIS Online. These and other web mapping services provide a standard means of accessing map data layers over the web and allow those data layers to easily be used in different software applications.

Using a web-services driven approach relies on data being published as web-services, and the amount of public data being published to the web is increasing every day. For more information on getting started finding available data, see our blog post on Mapping Resources.

This web map series is also intended as a learning platform for stakeholders who may discover additional data from other sources and are interested in integrating those data into a single map view. These maps are meant to provide a general guide, and illustrate how such data may be useful, and are not provided as the basis for individual risk determinations. They are not a substitute for reviewing your site individually. Your location and stakeholder community may have additional or differing criteria, or may desire simpler or more complex risk assignments.
