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 Engineer
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 t
Data Release for Multimodal Invasive Carp Deterrent Study at Barkley Lock and Dam: Status Update through 2022
The BioAcoustic Fish Fence (BAFF; Fish Guidance Systems Ltd.) is a multi-modal deterrent that utilizes a combination of lights, sound, and bubbles to guide fish away from a location. An experimental deployment of a BAFF is currently ongoing at Barkley Lock and Dam on the Cumberland River near Grand Rivers, KY. This dataset includes information derived from two telemetry arrays (i.e., VEMCO and HTI
Data Release for Lock 19 Underwater Acoustic Deterrent System (UADS) Study: Interim Project Update
The Underwater Acoustic Deterrent System is an experimental deterrent that utilizes underwater sounds to deter invasive carps. An experimental deployment and evaluation of a UADS is currently being conducted at Lock 19 on the Mississippi River, near Keokuk, Iowa. This dataset includes information derived from two telemetry arrays (i.e., 307 kHz HTI and 69 kHz VEMCO) deployed at and around Lock 19
2017-2019 Telemetry data for invasive carp and paddlefish surrounding Lock and Dam 15 in the Upper Mississippi River Basin
This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 15 on the Mississippi River near Rock Island, IL and a longitudinal telemetry array that ranges from Pool 14 to Pool 19. Silver carp, bighead carp, and paddlefish were detected with this system. Lock Queue Reports, which detail the daily lock operation for river traffic, were obtained from the U.S. Army
Food web fatty acids and stable isotopes in the Upper Mississippi River Basin 2013-2014: Data
This dataset includes information from multiple taxa collected from four main reaches in the Upper Mississippi River Basin, including La Grange reach of Illinois River, Pool 2 of Mississippi River, Pool 19 of Mississippi River, and the St. Croix River. Taxa include hydropsychid caddisflies, chironomids, hexagenia mayflies, threeridge mussels, mapleleaf mussels, Wabash pigtoe mussels, bigmouth buff

Flooding and dam operations facilitate rapid upstream migrations of native and invasive fish species on a regulated large river
Dams commonly restrict fish movements in large rivers but can also help curtail the spread of invasive species, such as invasive bigheaded carps (Hypophthalmichthys spp). To determine how dams in the upper Mississippi River (UMR) affect large-scale invasive and native fish migrations, we tracked American paddlefish (Polyodon spathula) and bigheaded carp across > 600 river km (rkm) and 16 navigatio

USGS invasive carp database management & integration support
Invasive carp tracking, monitoring, and contracted removal will continue throughout the Upper IWW system as part of an adaptive management effort to mitigate, control, and contain invasive carp. To help facilitate these actions, there is a need to compile and analyze data from the multitude of partner agencies that are collecting invasive carp-related data throughout the Illinois River system.

Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river
Fish movements in regulated rivers can be challenging to study because anthropogenic modifications, such as locks and dams, can influence animal behavior. Upper Mississippi River Lock and Dam 19 (LD 19), for example, is an invasive carp movement bottleneck due to an impassable dam. Upstream fish passage at LD19 is restricted to the lock chamber, making it an optimal location to test invasive fish
