St. Francis Dam Flood March 12-13, 1928, Los Angeles County, California. Final resting place of several huge concrete blocks from the west abutment of the dam, about one-third of a mile downstream from the dam. The tractor in the foreground marks the flood water line. March 17, 1928.

Panorama of images 1211 and 1212 as seen in W.C. Alden's photo album. View of Shoshone Reservoir west of Cody. At left, canyon in which is Shoshone Dam. Shows Paleozoic and Mesozoic limestones and shales overlying granite on Rattlesnake anticline in Cedar Mountain, cut through by the canyon. Reservoir in broad valley to west (right). Park County, Wyoming. June 15, 1922.

Barrier No. 1, Yuba River. The water flows over part of dam built in 1904. The piles are part of the addition of 1905. Yuba County (?), California. June 6, 1905.

This CSV file contains 21 dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous USA. Dam metrics fall into four main categories: segment-based, count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using spatially verified large dam locations (n=49,468) primarily from the National Anthropogenic Barrier Dataset (NABD) that were spatially linked to the National Hydrography Dataset Plus version 1 (NHDPlusV1). These dam metrics have been summarized using the unique identifier field native to the NHDPlusV1 (COMID) which can be used to join this table to spatial layers and data tables of the...

These tabular data are summaries of human related landscape variables within catchments of the Chesapeake Bay watershed using the Xstrm methodology at 1:24,000 scale. Variables being counted as human related include agriculture, barriers, road density and road/stream crossing data. Outputs consist of tabular comma-separated values files (CSVs) for both local catchment and network summaries linked to the National Hydrography Dataset Plus High-Resolution (NHDPlus HR) framework by NHDPlus ID. Local catchments are defined as the single catchment the data is summarized within. Network accumulation summaries were completed for each of the local catchments and their network connected upstream and/or downstream catchments....

Cone of hydraulic tailings on Wedge Gulch. The tailings were partly caught by a restraining dam, and the mass afterward eroded when the dam gave out. Big Trees quadrangle. Calaveras County, California. 1905. Published as plate 5-A in U.S. Geological Survey Professional Paper 105, 1917.

View west up Shoshone Reservoir from top of Shoshone Dam, west of Cody. Cliffs of granite and gneiss. Park County, Wyoming. June 16, 1922.

This tabular data set contains decadal information on dams compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for dam information was produced by the United States Army Corps of Engineers. The information provided here contains the number of dams (both major and minor), dam storage (acre feet) and decade of construction compiled as described above. Reach catchment information characterizes data at the local scale. Reach catchments accumulated...

This dataset describes attributes of surface-water impoundments derived from the National Inventory of Dams (NID), National Land Cover Data (NLCD) and the National Hydrography Dataset Plus (NHDPlus). Reservoir surface areas were determined using National Inventory of Dams Reservoir Surface area, NHDPlus Waterbody area, and National Land Cover Data (NLCD) open water body area as data sources. National Inventory of Dams were indexed on NHDPlus V2.1 using several sources and methods which are described in detail in the Process_Description section. The open-water classification in the NLCD was used to extract open water areas.
