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...

Collection of bathymetric quality-assurance data in September 2018 at Sugar Creek Lake near Moberly, Missouri, used a marine-based mobile mapping unit that operates with several components: a multibeam echosounder (MBES) unit, an inertial navigation system (INS), and a data acquisition computer. Bathymetric quality-assurance data were collected using the MBES unit at 4 transects oriented perpendicular to the longitudinal transects of the bathymetric survey data. The resulting bathymetric dataset was minimally processed using filters in the HYPACK/HYSWEEP software (http://www.hypack.com) to remove data spikes or erroneous points. The resulting bathymetric quality-assurance data set contained approximately 8.7 million...

Collection of bathymetric data in September 2018 at Sugar Creek Lake near Moberly, Missouri, used a marine-based mobile mapping unit that operates with several components: a multibeam echosounder (MBES) unit, an inertial navigation system (INS), and a data acquisition computer. Bathymetric data was collected using the MBES unit in longitudinal transects to provide complete coverage of the lake. The MBES was tilted in some areas to improve data collection along the shoreline, in coves, and in areas that are shallower than 2.5 meters deep (the practical limit of reasonable and safe data collection with the MBES). The resulting bathymetric dataset was processed using filters in the HYPACK/HYSWEEP software (http://www.hypack.com)...
