Fosness 2014 U.S. Geological Survey Data Series 889, 9 p Reston, VA U.S. Geological Survey http://doi.org/10.3133/ds889 The minor clay step features are defined as having a vertical face that is less than or equal to 1.5 meters. The clay step features were qualitately identified using an underwater video monitoring sysyem. The extent and magnitude of the clay steps were mapped using a muliteam bathymetric echosounder system. The minor clay steps can be used to define the benthic habitat characteristics near current white sturgeon spawning grounds. The data may provide unrealized areas of species preferred habitat. 2007 2013 ground condition Complete As needed -116.416180 -116.412357 48.745298 48.738344 USGS Thesaurus topography swath bathymetry Hypack Hysweep USGS ASCII Geology inland waters Bathymetry Water Depth inlandWaters Multibeam XYZ U.S. Geological Survey ISO 19115 Topic Category inland waters bathymetry elevation islands lidar lakes capacity USGS Metadata Identifier USGS:ddba2324-8231-41bf-9753-c77e3afe5047 Geographic Names Information System (GNIS) Bonners Ferry USA Kootenai River Idaho ID None Although these data have been used by the U.S. Geological Survey, U.S. Department of the Interior, these data and information are provided with the understanding that they are not guaranteed to be usable, timely, accurate, or complete.

No tests were used to check the consistency of the data. There are likely substantial areas of error within the data; however, the data provides a general description of the minor clay steps within the study area. The data is complete. unknown unknown Video clips were recorded at discrete, equal-width increments along designated cross sections. The video clips were recorded using a high-resolution, color video camera outfitted with two high-power laser pointers. The laser pointers had a constant 10-cm separation as a scale of reference to determine sediment grain size. The camera was lowered through the water column until it was near the bed and the substrate could be identified. Each video was then reviewed to determine sediment size and embeddedness. Unknown A separate study using multibeam echo sounding resulted in a nearly seamless digital elevation map of the channel bed. This bathymetry was layered behind the sediment facies map to identify sediment category boundaries, and to delineate the sediment facies, such as sand dunes and clay steps. 20140401 Esri ArcGIS™ was used to create a GIS layer defining the minor clay step features at Myrtle Bend based on the analysis of the video recordings and the multibeam bathymetry data. 20140401 The metadata was created. 20140401 Vector String 98 NAD 1983 UTM Zone 11N 0.9996 -117.0 0.0 1640416.666666667 0.0 coordinate pair 0.000000007283507130750879 0.000000007283507130750879 foot_us D NORTH AMERICAN 1983 GRS 1980 6378137.0 298.257222101 ClaySteps_minor_MB Dataset showing in-stream terraces larger than 1 meter; composed of consolidated glaciolacustrine sediment (clay) that have been produced by renewed downcutting of the flood plain or valley floor USGS Shape Feature geometry.
