Each instream flow reservation record for flowing waters is represented by a single stream centerline extracted from the USGS National Hydrographic Dataset. The dataset is attributed with stream name, applicant name, reservation status (applied or issued), and the Alaska Department of Natural Resources (ADNR) Land Administration System (LAS) number. The dataset has been generated by using a combination of the geospatial data distributed via ADNR's Alaska Mapper application and the listing of specific Sections with water reservations from the LAS records.
