Data release associated with research that describes how major flooding and dam operations in the upper Mississippi River contribute to large upstream migrations of native paddlefish and invasive bigheaded carp Recent research has attributed major flood events with the upstream spread of invasive carp in the Mississippi River. In two sequential years, the upper Mississippi River experienced a low water year with very minimal flooding in 2022 and a very high water year with extreme and sustained flooding in the spring of 2023. This data release contains hydrologic data from the U.S. Army Corps of Engineers at upper Mississippi River navigation locks 4-18 to classify when each dam experienced open river conditions and was no longer preventing upstream movements of fishes. To attribute biological movements around these open river conditions, we used acoustic telemetry data to track native paddlefish and invasive bigheaded...

Data release for an experimental translocation of invasive bigheaded carps and upstream passage success at a navigation lock This dataset accompanies the article "Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river". The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit signals that are detected and recorded on receivers that are strategically placed above, within, and below Mississippi River Lock and Dam 19 (LD 19). Once the data from the receivers were downloaded, we could show when successful upstream passage through LD19 occurs and compare the origin of the fish and the physical characteristics...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
