This dataset and final report from the upper Kuskokwim River at McGrath, Alaska is the result of a recent river resource and siting assessment conducted by the Alaska Center for Energy and Power (ACEP) and Pacific Marine Energy Center (PMEC) at the University of Alaska Fairbanks (UAF). This work was requested by the City of McGrath, funded by the U.S. Department of Energy (DOE) Testing and Expertise for Marine Energy (TEAMER) Program and is described in detail in the TEAMER Post Access Report. The aim of the study was to evaluate hydrokinetic river energy (RHK) resources and evaluate potential locations to determine the feasibility of potential RHK development in future to support meeting community energy needs with local renewable energy. This submission contains raw acoustic Doppler current profiler (ADCP) data, raw single beam echosounder (SBES) data, raw onset HOBO U20-001-01 and U20L-04 pressure sensor data, global navigation satellite systems (GNSS) data, and bathymetric model outputs. This study focused on the river resource available during the summer open water season (OWS) between May-October and did not evaluate the river resource during the winter (November-April), when the surface of the Kuskokwim River is frozen. The dataset includes raw and processed data and modeling results from fieldwork conducted during the summer OWS in 2024. Fieldwork involved two separate time periods in August (high water) and October 2024 (low water) to capture the variability of the Kuskokwim River at this location during the OWS. A description of the instrumentation, software, and data files is included in the metadata. The City of McGrath would appreciate being contacted by users of this dataset, primarily to understand how the dataset is being used and if it could lead to future developments that could benefit our community.
