Display Field: Dam_Name

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This layer includes dams characterized by the Chesapeake Fish Passage Prioritization project by The Nature Conservancy (TNC, http://maps.tnc.org/EROF_ChesapeakeFPP/), represented as points. Metrics encompassing five categories (connectivity status, connectivity improvement, watershed/local condition, ecological, and site/system type) were calculated for each dam, weighted, and combined to provide a ranking for each dam (Martin and Apse, 2013). for three scenarios (diadromous fish, resident fish, and brook trout). Dams were tiered into twenty 5% bins based on their potential to benefit each scenario if removed or passage is provided. For example, dams in Tier 1 would provide the greatest ecological benefit (high priority), while those in Tier 20 would provide the least (low priority). These results are intended to be a screening level tool to help managers determine fish passage priorities. Dams and their tiered ranks were obtained for diadromous fish scenario and were extracted for the Choptank HFA.
