Data were collected to: 1) characterize multivariate water chemistry signatures (Sr:Ca, Ba:Ca and δ18O) among the Upper Mississippi River, its tributaries, and the Missouri and Middle Mississippi rivers; 2) infer environments occupied during early life stages by bigheaded carps collected in Upper Mississippi River Pools 19-21 using otolith microchemistry and stable isotope analyses, and (2) use early life environment assignments and capture location to identify individuals that passed through Lock and Dam 19. Water chemistry data will be potentially useful as baseline data for studies using calcified structure chemistry to infer environmental history of other fish species in the Upper Mississippi River. Bigheaded carp otolith chemistry data and data on early life environments of fish sampled for this project will potentially be useful for future studies to assess how early life environments supporting recruitment of these species in the Upper Mississippi River may have changed over time.
