20221206 13493700 1.0 TRUE Choptank Fish Passage 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. The Nature Conservancy
