Huizinga, R.J., 2019, Topography at Selected Dams in the Mark Twain National Forest, Missouri, 2018: U.S. Geological Survey data release,


The U.S. Department of Agriculture - Forest Service (USDA-FS) has been evaluating hazards and classifications at the dams of four small reservoirs in the Mark Twain National Forest in Missouri. These reservoirs are Crane Lake near Annapolis, Fourche Lake near Briar, McCormack Lake near Greer, and Sterling Hollow Lake near Willow Springs. Conventional topographic surveys were used to provide data needed for as-built information of the earthen dam structure, spillways, and groins at each of the dams. High-resolution terrestrial light detection and ranging (T-LiDAR) data also were collected for the concrete spillway structure at Crane Lake Dam to provide baseline data for potential monitoring and change detection. These data are useful [...]

Topographic data were collected within the study area to capture the geomorphological and physical characteristics of the above-water portions of the dam and spillway appurtenances. These data are intended for science researchers, policy makers, and hydraulic engineers interested in assessing the condition of the dam structure, and to monitor changes with time. The bmp raster file was included to provide a preview of the topographic data contained in these datasets. The attached zip file called "" contains 5 separate files: two comma-delimited ASCII text files of the LiDAR data (with and without vegetation layer enabled) with XYZ data with RGB color and classification, a metadata file for each, and a bmp raster preview image for the LiDAR survey at the site. The attached zip files called "", "", "", and "" each contains 3 separate files: a comma-delimited CSV text file of the total station data, an associated metadata file, and a bmp raster preview image of the total station survey at the site.
