The U.S. Geological Survey (USGS) intends to fund a project focused on updating the National Hydrography Dataset (NHD) in the Big Lost and Lemhi Basins, partnering with the Idaho Department of Water Resources (IDWR). This cooperative agreement, amounting to $30,000, aims to enhance the accuracy and relevance of hydrographic data, which currently does not reflect recent changes on the ground. The IDWR will utilize NAIP imagery, historical maps, and existing local data to update digital hydrography, including key features such as tributaries and fish passage barriers. IDWR, which serves as the central cooperator and possesses unique qualifications for this task, will report findings and developments to the NHD Advisory Team. The justification for sole-source funding is based on IDWR's extensive experience with the NHD in Idaho, making it uniquely qualified for the project. This initiative underscores the importance of collaborative efforts in environmental data management and aims for transparency by keeping updated information publicly accessible.
