Hyperspectral and RGB image data used to map salmon spawning locations on the American River, California, November 5-7, 2018 An unmanned aerial system (UAS) was used to acquire red/green/blue (RGB) and hyperspectral image data from the American River in California November 5-7, 2018, to support research on remote sensing of rivers, specifically mapping chinook salmon spawning locations (redds) as part of an overall salmon habitat assessment program. The RGB images were acquired uisng a DJI MAtrice 210 equipped with a Zenmuse 4S optical camera. Imagery was collected along several parallel flight lines to ensure full coverage of the study reach. Raw Zenmuse images were georeferenced using real-time kinematic (RTK) global positioning system (GPS) and inertial motion unit (IMU) data recorded onboard the UAS and individual flight strips were...

The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely sensed data. Traditionally, redds have been mapped by eye while walking the bank or from a boat, or by an observer in an aircraft or an interpreter visually examining aerial images. The goal of this proof-of-concept investigation was to assess the potential for more efficient, objective, and automated...

These data sets were intended to characterize salmon spawning habitat and identify factors influencing spawning site selection. This parent data release includes links to child pages for the following data sets: 1) Bulk samples of streambed sediment used to characterize the subsurface grain size distribution. 2) Pebble counts used to characterize the sediment grain size distribution of the bed surface. 3) Force gage measurements used to parameterize a...

A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. The bulk samples were acquired during the summer of 2016 at the Merced River Ranch and Robinson Reach field sites using a McNeil sampler [McNeil and Ahnell, 1964]. Before collecting each sample, the surface layer was removed to avoid including surface grains as part of the sample. Surface material was scraped off to a depth...

A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. The pebble counts were performed at the Merced River Ranch and Robinson Reach field sites using the method of Wolman [1954].

Building upon our initial barrier inventory, this project has two key elements. First, we are testing whether our landscape statistical models accurately predict the upstream limits of fish migrations along the Wisconsin coast of Lake Michigan. This involves intensive field work to determine the actual upstream limits of suckers, pike, and steelhead during the spring migration. Second, we are collecting systematic data on the size and condition of dams throughout the Lake Michigan basin. These...

A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. Saturated hydraulic conductivity, denoted by K, was measured with a backpack permeameter and modified Mark VI groundwater standpipe using the constant head method of Terhune [1958]. For each reach, permeameter measurements were collected at ten sites spanning a single...

The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor S5 acoustic Doppler current profiler (ADCP) deployed...

Information about existing river habitat, current patterns, fish nursery areas, movements, spawning, and early life habitat requirements are being used in adaptive management models to identify areas suitable for creation or restoration of fish habitats. Physical and biological information are being coupled to show where and how habitat restoration will produce the strongest benefits to native fishes at multiple locations in the St. Clair and Detroit...
