U.S. Fish and Wildlife Service supplied data for hydraulic modeling at selected dam-removal and culvert-retrofit sites in the northeastern United States

This dataset contains US Fish and Wildlife Service (USFWS) supplied data, for eight dam-removal sites in the northeastern United States (Olson and Simeone, 2021). The USFWS provided the U.S. Geological Survey with data to support the development of one-dimensional and two-dimensional U.S. Army Corps of Engineer (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) models for the pre-dam removal conditions. The referenced models were used to evaluate fish passage and flood risk along the simulated reaches in the various states simulated. These data consist of topographic, bathymetric, and hydraulic structure data which are primarily in the form of .dgw computer-aided design files, available hydraulic models in HEC-RAS [...]
