Selected reservoirs in the state of North Dakota was surveyed to assess their storage capacity, sedimentation characteristics, water quality parameters, and check for leakage. The purpose of the study is to understand the dynamic of reservoir sedimentation in North Dakota and the effect on its resiliency and sustainability. The HYCAT, which is an autonomous surface vehicle, was interfaced with a side scan sonar and global positioning system. The side scan sonar soundings at a determined frequency was used to measure reservoir bed level and deposited sediments while the positioning system would provide information along the grid lines. Additionally, this bathymetry data was compared to previous survey data from reliable databases to evaluate storage capacity and storage loss or gain over the years. The water quality parameters of the selected reservoirs were monitored using the EX02 Sonde. This informed further discussion on the suitability of the reservoir to perform the functions for which it was originally designed. While sedimentation is the immediate concern, other studies that will be investigated in stage two of this research would be to investigate the factors affecting PFAS distribution along the reservoir.
