Description: This is a combined dataset of the OHWM and culverts/undergound pipes for the Stibnite Gold project from three sources: a compiled dataset containing streams delineated by HDR during the 2011-2016 field seasons, stream data delineated by Tetra Tech in the 2018 field survey, and the National Hydrography Dataset (NHD) flowline dataset for Idaho retrieved in 2018. This same dataset includes the 2017 Logistics Center delineation as no additional OHWM's were added for that effort. This dataset includes delineations conducted in 2015 along the Powerline corridor. Since access was not obtained on private lands along the powerline corridor, the stream shown in that report and dataset are not to the same level of field work as completed in the other field seasons.Stream segments were added in 2016 on the BL alignment and the camp area to connect OHWM areas for analysis purposes.To show culverts in lieu of stream segments for cartography, use a def query to hide the stream segments with DisplayLine = "culvertrem". To calculate stream impacts, use a def query to hide culverts and pipes (FeatureType not in ('culvert','pipe'))Tetra Tech added fields- TTJurisdictional_Determination- USACE jurisdictional determination. Source-[Documents that convey the Jurisdictional Determination], TTCulvert_dup-[To calculate stream impacts, use a definition query to hide duplicate culvert and pipe polylines (Culvert_dup <> 'Y')], TTStreamName-[Tetra Tech modified stream names], TTDrainage-[Tetra Tech modified drainages], TTWatershedName-[GNIS name for the geographic area in which the hydrologic unit is located from the USGS National Watershed Boundary Dataset], TTHUC10-[10-digit hydrologic unit boundaries from the USGS National Watershed Boundary Dataset], TTHydrographic_Cat-[Updated hydrographic category with attributed 2015 type].Ecosystem Sciences used LiDAR data to true-up existing ephemeral stream channels and to add new ephemeral streams to the dataset. Tetra Tech modified existing stream delineations to match Ecosystem Science LiDAR data and added hydrography and stream reaches from Rio.Streams delineated and/or field verified during the 2018 field season and NHD datasets were added to the dataset in order to create a single dataset with coverage for the entire project area using the most current and highest resolution data available at the time.This dataset and metadata was last edited on 8/16/2019.
