It also includes area downloads for HEC-RAS (Hydrologic Engineering Center\u2019s River Analysis System) modeling. HEC-RAS software allows the user to perform one-dimensional steady flow, one and two-dimensional unsteady flow calculations, sediment transport/mobile bed computations, and water temperature/water quality modeling. (More information)For downloadable layers: At the link above, select Map Layers, then Data Availability (BLE), select \u201cOn\u201d for status & data download. Click an area on the map to view downloadable datasets.Statewide BLE data is expected to be available on the BLE website for download by summer 2025. To see the current progress of BLE development throughout the state and the status for a given watershed, please see the BLE Status Dashboard here: BLE Status Dashboard (arcgis.com).
