Here we offer RAD-seq data to show that levels of connectivity of a winged stonefly with groundwater larvae and an obligate groundwater amphipod show similar levels of connectivity between floodplains separated by 40 km in the Flathead River basin of NW Montana, USA. This may be due to deep phreatic water connections that enhance movement of organisms between these populations.
