Strauch 2008 online publication Data Series DS332 Lincoln, Nebraska U.S. Geological Survey https://pubs.usgs.gov/ds/332/ This point data set contains streamflow-measurement sites in the Elkhorn and Loup River basins and selected streamflow-measurement sites in the Niobrara and Platte River basins in north-central Nebraska. At these 531 sites, flows ranging from no flow to 2,600 cubic feet per second were measured or observed during November 8 to 21, 2006. Measurements were made by several different methods, including current meters, flumes, and acoustic Doppler velocimeters. Each measurement site location was recorded using a handheld global positioning system (GPS) unit and then downloaded and stored in a computer spreadsheet. Stored coordinates were used to produce point features in GIS native format. This data set was developed to archive the streamflow measurements collected for streams in the Loup and Elkhorn River basins and selected streams in the Platte and Niobrara River basins in November 2006. The data are suitable for use with geographic information systems (GIS). The data set also includes the geographic coordinates of each measurement site. 20061108 20061121 ground condition Complete None planned -102.030514 -97.291125 42.854450 40.890575 Water Resources Thesaurus tributaries seepage streamflow base flow low flow ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Metadata Identifier USGS:23738f6e-e456-4437-a0f8-338aa94263ca Geographic Names Information System (GNIS) Nebraska Loup River Niobrara River Elkhorn River Platte River none none Kellan R.

Also, the authors appreciate the support of personnel from the Lower Loup, Lower Platte North, Upper Loup, and Upper Elkhorn Natural Resources Districts (NRD) who were critical to its success by providing site selection assistance to identify favorable access to streams, coordinating stream access with local landowners, and logistical assistance during data collection. Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.4.1420 Accuracy of attributes was verified by checking against the original source data (field notes) from streamflow measurements to ensure valid and accurate data entry. Chain-node topology present. All measurements of streamflow during base-flow conditions in November 2006 were included. Horizontal positions were downloaded from a handheld GPS. 10 feet No additional accuracy assessment was conducted. Horizontal accuracy value is the maximum value reported by the handheld GPS, which was operated with WAAS enabled, and without coordinate averaging. Points were stored in a handheld GPS when streamflow measurement was made, the saved point was located somewhere along the transect where measurement was taken. GPS units that hand the WAAS feature were used with the WAAS enabled, and were turned on and collecting data long enough to ensure that the feature had reception. 20061108 Uploaded coordinates from handheld GPS, and stored in a computer spreadsheet. 20061205 Defined projection as geographic, using decimal degrees referenced to North American Datum of 1983. 20071031 Produced a GIS native-format data set. 20071031 Reprojected to Nebraska State Plane Coordinates, using units of feet. 20071031 Dataset copied.
