The lake primarily is used for recreation and drinking-water supply for the town of Moberly, Missouri. An earthen dam approximately 38-feet high and 1,125-feet long was constructed across the Sugar Creek valley in 1922. The elevation of the top of the dam is approximately 754 feet, with a 90-feet wide concrete spillway located near the right bank (west end) at an elevation of 746.8 feet. A previous bathymetric survey was completed in 2003. In cooperation with the Missouri Department of Natural Resources, the U.S. Geological Survey resurveyed the bathymetry of the lake in September 2018 to provide data to update the area-capacity table and to compare the current bathymetric surface with the previous bathymetric surface. The shoreline was created from lidar derived 1/9 arc-second elevation data obtained from https://viewer.nationalmap.gov/basic/. The data are provided in the Environmental Systems Research Institute (ESRI) shapefile format and have the common root name of scl_shoreline. All files in the shapefile group must be retrieved to be useable. Two bathymetric data sets are included: the gridded bathymetric point data (scl_bath.zip; computed on a 1.64-foot grid using the combined uncertainty and bathymetric estimator method) that was used as the source of points to create a bathymetric surface and the bathymetric quality-assurance data set (scl_qa_raw.zip) from 4 selected resurvey areas that was used as quality assurance data to test the accuracy of the gridded bathymetric point data. The Missouri Department of Natural Resources (MDNR), Water Resource Center and Missouri's Safe Drinking Water Program has the responsibility of assisting state residents in assuring an adequate and safe water supply. As a result, a water supply study has been ongoing to ensure availability of water information for effective decision-making by communities and MDNR program managers. One of the benefits of the study is to determine and allocate existing water supplies, with the scope of the study to addresses surface-water supplies for cities and communities that are expected to experience water shortages during an extended drought. Surface-water supplies consist of lakes and streams and in many cases combinations of both. Water supply lake bathymetric surveys are integral to the water availability assessments during potential water shortages. 20180905 20180906 Date of survey.

No formal logical accuracy tests were conducted. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable. Data were obtained from https://viewer.nationalmap.gov/basic/ as lidar derived 1/9 arc-second elevation data for the area of interest. The 1/9 arc-second elevation data was resampled to a 3.28-foot grid spacing using spatial analyst tools in the ArcGIS software. A contour line representing the lake spillway elevation of 746.8 feet was generated from the gridded data using the contouring tools in the ArcGIS software. This contour represents the extent of the lake shoreline when the lake is at full capacity. 2018 Vector String 22 Universal Transverse Mercator 15 0.9996 -93.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 meters D_North_American_1983 GRS_1980 6378137.0 298.257222101 Attribute Table Table containing attribute information associated with the data set.
