We present a new hydrological dataset collected during a field campaign in the Saigon-Dong Nai estuary system, Viet-nam. These data include water level and water tempera-ture measurements at five locations along the Saigon river and 2 locations along the Dong Nai river as well as dis-charge measurements from four 24-hour Acoustic Doppler Current Profiler (ADCP) campaigns at 2 locations in the Saigon river and 1 location in the Dong Nai river. Addition-ally, water level was barometrically compensated using air pressure measurements. Data were sampled between Octo-ber 21st, 2022 and December 16th, 2022 and are provided in three processing stages namely, direct measurements as provided by the sensors (raw), barometricaly compensated measurements (pre-processed) and corrected measurements (post-processed). Even though of short duration (about 2 months), this dataset provides water level measurements at unprecedented spatial and temporal resolution in a re-gion where data is scarce and not freely available. The syn-chronous logging of multiple water level sensors along river provides an opportunity to study profiles of water surface slope and upstream tidal propagation. Furthermore, the con-current discharge measurements can be used to calibrate hydrological and/or hydraulic models of this estuary system. Additionally, the spatial resolution of this dataset is similar to the prospective measurements that the novel Surface Water and Ocean Topography (SWOT) satellite will provide. Thus, it enables the study of synthetic SWOT measurements to eval-uate the future potential of the SWOT satellite over this es-tuary system
