Sample sites located within North America (panel a) in the Red River basin (panel b) that were used in our mark-recapture analyses of prairie chub movement. Tagging and searching sites were located on the Salt Fork Red River, the Red River, and the Pease River (panel c). The long searches were completed August 8–9, 2020 to look for relatively long-distance movers outside of our tagging and regular search sites. The 20-km search was completed August 10–12, 2020 to systematically look for tagged prairie chub above and below 4 of 6 sites along the Salt Fork Red River and the Red River (August 10–12, 2020). NHDplus flowline was used for the rivers [58]
