Grand Lake (Oklahoma) Multibeam Bathymetric Survey 2019

USGS Oklahoma-Texas Water Science Center Webinar Series - Friday May 7, 11 am Central


In cooperation with the Grand River Dam Authority, in the summer of 2019 USGS surveyed the Grand Lake O’ the Cherokees, which is locally called Grand Lake and located in northeastern Oklahoma. The survey was conducted to prepare an updated bathymetric map and surface-area and capacity table. Due to the natural changes to the reservoir, new capacity and area tables are needed periodically.  Capacity and area tables identify the relation between the elevation of the water surface and the volume of water that can be impounded at each water-surface elevation. This study (1) includes high-resolution multibeam bathymetric data, and (2) describes the methods used to collect and process the bathymetric data. The bathymetric map may serve as a baseline to which temporal changes in storage capacity, due to many natural factors, can be compared. The stage-storage relation may be used in the reporting of real-time Grand Lake O’ the Cherokees storage capacity at USGS station 07190000 to support water-resource management decisions by the Grand River Dam Authority.

     Shelby Hunter, USGS Southeast Region Safety and Occupational Health Specialist

BIO:  Shelby Hunter began working with USGS in Oklahoma in 2008 as a student intern working on surface water, groundwater, and water-quality projects. Upon completing a degree in Wildlife Conservation from Northwestern Oklahoma State University in 2011, he became a full-time USGS employee. Over the next several years, Shelby assisted in maintaining a network of real-time surface-water and groundwater gages. While maintaining these gages he had the opportunity to work on many USGS scientific investigations including seepage-flow and dam-breach studies. In 2017, he led a single-beam bathymetric study of over 70 miles of rivers in Northeastern Oklahoma. The next few years included more collaborative opportunities - including area and capacity studies, peak regression equation development, drone work of sampling river cross sections, and most recently lake multibeam bathymetric studies. Recently, Shelby transferred to the Southeast Region Office of the USGS to take on a new role as Region Safety and Occupational Health Specialist.
