Sandbars of large sand-bedded rivers of the Central U.S. serve important ecological functions to many species, including the endangered Interior Least Tern (Sternula antillarum) (ILT). ILT are colonial birds which feed on fish and nest primarily on riverine sandbars during their annual breeding season of approximately May through July, depending on region. During this time, ILT require bare sand of sufficient elevation so as not to be inundated during the period between nest initiation and fledging of hatchlings. ILT were originally listed as endangered due in part to decreases in available sandbar habitat from river channelization and impoundment. Sandbars in Central U.S. rivers used by ILT are highly dynamic,...

This dataset contains cross-sectionally averaged flow metrics from measurements made with acoustic Doppler current profilers (ADCP) on the Missouri River near Wolf Point, MT during 2018 and 2019. Each data point represents a single-pass measurement with a boat-mounted ADCP driven from bank-to-bank along lateral transects spaced ~15 meters apart along a 33 kilometer reach. The measurements were collected as part of a bathymetric survey in which two USGS survey boats were each mounted with an ADCP and single beam echosounder that were deployed simultaneously. Cross-sectionally averaged flow metrics such as velocity, depth, and temperature along with the total measured discharge and starting coordinate of the measurement...
