Sandbars of large sand-bedded rivers of the Central U.S. serve important ecological functions to many species, including the endangered Interior Least Tern (Sternula antillarum) (ILT). ILT are colonial birds which feed on fish and nest primarily on riverine sandbars during their annual breeding season of approximately May through July, depending on region. During this time, ILT require bare sand of sufficient elevation so as not to be inundated during the period between nest initiation and fledging of hatchlings. ILT were originally listed as endangered due in part to decreases in available sandbar habitat from river channelization and impoundment. Sandbars in Central U.S. rivers used by ILT are highly dynamic,...

This release contains geospatial data digitized from the Map Showing Geology, Structure, and Oil and Gas Fields in the Sterling 1x2 Degree Quadrangle, Colorado, Nebraska, and Kansas (Scott, 1978) and was compiled as part of the National Geologic Synthesis project. The geospatial data depicts the geology of this quadrangle, which is dominated by Quaternary alluvial and aeolian deposits overlying Tertiary and Cretaceous sedimentary rock, including the Ogallala formation, the Fox Hills sandstone, and the Pierre shale. The included database includes spatial data depicting the locations of mapped geologic contacts and faults, polygons denoting the mapped surficial extent of geologic formations, and structural contours...

These data are the survey results from a five-mile section of the Platte River at, and upstream of the Nebraska Army National Guard Camp Ashland Training Site including the side channel chutes on the east bank. All survey data were collected along planned transect lines that were spaced 492.125 US survey feet apart beginning near the mouth of the Elkhorn River and ending near the U.S. Highway 6 bridge. An effort was made to get complete elevation data for each transect from top of bank to top of bank. Survey grade Global Navigation and Satellite Systems (GNSS) receiving antennas connected to a real time network (RTK high precision network https://hprtk.net) were used to measure elevation along the transects, at...

These historic photographs may be useful in documenting changes in the condition of the Platte River. Each of the photographs were scanned at 600dpi and compressed using M.zip software from LizardTech. M.zip compressed images may be viewed using a free viewing software package available from LizardTech. Software extensions allowing M.zip images to be used in Adobe Photoshop are also available. These photos are available on USGS Nebraska Water Science Center website at: http://ne.water.usgs.gov/platte/historical1938.html In addition to being provide in this ScienceBase record, the photographs are stored on USGS National Geospatial Program servers (web domain http://thor-f5.er.usgs.gov/platteriver/1938).

This data set contains two sets of water-level contours that represent interpreted water-levels for an area between the Platte and Elkhorn Rivers just above their confluence. The contours are informed by surface-water and groundwater-level data collected during the fall of 2016 during synoptic water-level survey completed during a low-groundwater demand period and a summer 2017 synoptic water-level survey completed during a high-groundwater demand period. The additional data and interpretations provided with this data set and the larger data release are intended to inform water managers of the effect flow conditions on groundwater movement and interaction with surface-water above the confluence of the lower Platte...

While habitat selection and population estimates are well documented for spring migrating birds in the central Platte River system, little information or monitoring efforts on the North Platte River exist, particularly for the multiple priority bird species known to be present. Most conservation partners deliver habitat programs in the region with limited information and a lack of a landscape prioritization tools. In order for conservation delivery to be more effective and efficient in utilizing limited funds, a decision support tool is critical so that priority species habitat needs are being addressed through appropriate restoration/management strategies in the correct geography at multiple scales. We propose...

The U.S. Geological Survey (USGS), in collaboration with the Platte River Recovery and Implementation Program, collected capacitively coupled (CC) resistivity data and six direct push sediment cores to identify the coarsest alluvial deposits underlying the Morse properties in central Nebraska to supplement the subsurface geologic information, for the purposes of proper siting of intentional recharge structures, and to improve current understanding of groundwater movement. The subsurface geology is described in three different data sets in varied file formats. First, for the direct-push cores, data are given as detailed descriptions of core lithology and texture and are provided in Comma Separated Values (CSV) file...

This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....
Priority and use segments for Sandhill Cranes (Antigone canadensis). Segments designated as use areas were utilized during annual spring surveys 2014-2016. Priority areas were determined using statistical modeling. The reduced model that best predicted use by Sandhill cranes included total area of trees, pits, crops and unvegetated sandbar habitats in each segments. Mean distance to conservation lands and roads and minimum distance to transmission lines and towers were also included in the model. Only distance to lines and total tree area had a significant (p < 0.05) relationship with priority core segments.

Aerial surveys with locations, habitat type, and count estimates for Sandhill Cranes (Grus canadensis) and waterfowl. Waterfowl were distinguished between ducks, dark geese, and light geese. Habitat types described include: main channel, side channel, pond or wetland, and field adjacent to river, pond, or wetland. Crane and waterfowl habitat use was collected on the North and South Platte Rivers from the confluence of the North and South Platte River near North Platte, Nebraska to the Nebraska state line. Survey data was used to create habitat use models for ducks, geese, and sandhill cranes.

The central Platte River Valley represents a key mid-latitude stopover. This dataset supports a contemporary analysis of spring migration phenology at the Platte River during 2001-2007. We recorded timing of sandhill crane arrivals and departures from the Platte River.
