Data were collected in June 2016 as part of a dye-trace experiment in the Missouri River downstream from Fort Peck Dam, Montana, USA. Fluorometers were deployed at 8 measurement stations over a 135-km study reach. Approximately 51 L of Rhodamine WT (RWT) dye was injected on 26 June 2016 at 14:30 MDT. The injection occured along a transect located approximately 3000 meters downstream from the confluence of the Milk and Missouri Rivers. Injection was performed via a gravity-feed system and was complete within seven minutes of initaition. RWT dye was diluted by at least half to facilitate mixing and was injected approximately 0.30 m below the water surface. Fluorometers were placed approximately 4 to 8 m from shore...
We measured ontogenetic changes in routine and maximum swimming speeds of bighead, grass, and silver carp larvae. Daily measurements of routine swimming speed were taken for two weeks post-hatch using a still camera and the LARVEL program, a custom image-analysis software. Larval swimming speed was calculated using larval locations in subsequent image frames and time between images. Using an endurance chamber, we determined the maximum swimming speed of larvae (post gas bladder inflation) for four to eight weeks post-hatch.

Data consist of geolocation, temperature, turbidity, time, and dye concentrations collected at four downstream locations from Rhodamine WT dye injection point on Yellowstone River in June 2017
1: Model Archive: Simulation of Rhodamine Dye Concentration and Larval Drift, Kootenai River, Idaho. This archive contains results of lagrangian particle-tracking (LPT) simulations of both the dispersal of rhodamine dye and larval drift. The LPT model is a research effort and the simulations here provide some of the first experimental validation of the results for dispersal of a conservative constituent (Rhodamine WT-20). The larval drift simulations however have not been validated and the results should be viewed in this context. The simulations may contain 20 - 30 Gb of results. The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files...
