Lidar derived shoreline for Sugar Creek Lake near Moberly, Missouri, 2018

Sugar Creek Lake is located approximately 4 miles northwest of Moberly, Missouri, in Randolph County, and has a full-pool surface area of approximately 330 acres. 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.
