A two-week field operation was conducted in the John Day Reservoir on the Columbia River to image the floor of the pool, to measure the distribution and thickness of post-impoundment sediment, and to verify these geophysical data with video photography and bottom sediment samples. The field program was a cooperative effort between the USGS Coastal and Marine Geology Team of the Geologic Division and the USGS Columbia River Research Laboratory of the Biological Resources Division. The data collection was completed aboard the R/V ESTERO during September 13-27, 2000.
The interest in sediment accumulation in the reservoir was two-fold. First, it was unknown how effective this reservoir was as a sediment trap to material that otherwise would have been transported down-river to the estuary and eventually to the ocean. The recent erosion of beaches along the Washington coast has been attributed to a decreased contribution of sediment from the Columbia River to the coastal system due to the damming of the river. Second, sediment accumulation on the floors of reservoirs along the Columbia River has been suggested to be diminishing salmon spawning grounds. The extent of changes in habitat since construction of the John Day Dam, however, had not been documented. Common data sets were needed to address both of these questions, and for these reasons this geophysical and sampling program was undertaken.
This shapefile is intended to provide an interpretation of the sidescan-sonar imagery collected in the John Day Reservoir.

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added the link to the data catalog page in the Identification section, and a link to the publication in the Larger Work Citation. Added online link to the data in the Distribution section. Added a link to the field activity. Added the Distribution Liability. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

Dep_type contains Miocene, Quaternary, and boulders. The boulders are believed to be deposited as a result of the Missoula floods, so the argument could be made that these are fluvial deposits. However, in this case, fluvial deposits refers to more modern deposits formed as a result of the Columbia River pre-impoundment.
The Area and Perimeter calculations were done in ArcView 3.3 using the sample script calcapl.ave. The view projection was defined as Washington State Plane South, NAD83 in order to have the units in meters and be consistent with the projected sidescan-sonar imagery.
