River Valley Boundaries Generated for Select Large Rivers of the Upper Midwest, United States

River valley boundary extents were generated for select large river floodplains of the Upper Midwest, United States. These polygons were delineated using a method that incorporated interpolating a water surface elevation that completely over-topped water-control structures within the valley such as levees, flood walls, and roadways. The intersection of this derived water surface and land

Mussel Density Quadrat Sampling Locations in West Newton Chute from 2008 to 2017

Since 2008, over 1,400 quadrats and about 2,500 mussels have been systematically sampled within West Newton Chute (WNC), contributing to a diverse assemblage of 25 live species, including 2 federally endangered species, and 10 Minnesota listed species. West Newton Chute is a 2.4 km long side channel in Navigation Pool 5 of the Upper Mississippi River and has an overall aquatic are

Conserving Minnesota’s native mussel legacy: Quantifying habitat interactions

To quantify the responses of native mussel to the range of environmental conditions in the Minnesota River and St. Croix River basins, laboratory experiments will examine the physiological responses of mussels to different levels of suspended sediment and bed instability over a range of flow rates. Experiments will be conducted in the Outdoor StreamLab and flumes at the St. Anthony Falls...

Optimum electrofishing waveforms and parameters to induce immobilization of juvenile Grass Carp: Data

Grass Carp (Ctenopharyngodon idella) are a non-native species to North America that were first introduced for vegetation control in the 1960s. However, wild-reproducing Grass Carp can negatively impact aquatic habitats and aquatic communities by consuming substantial amounts of aquatic vegetation and increasing turbidity. Numerous fisheries techniques have been used in an attempt to contr...

Auditory thresholds for bighead and silver carp after sound exposure determined by the AEP technique: Data

Invasive silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp, collectively referred to as bigheaded carps, threaten aquatic ecosystems of the Upper Midwestern United States. Due to extensive ecological impacts associated with these species, prevention of their further range expansion is the aim for fisheries management. Recent behavioral studies indicate bigheaded car

Conserving Minnesota’s native mussel legacy: Quantifying habitat interactions

The goal of this project was to quantify the background physiological condition of mussels in the Minnesota and St. Croix River basins using glycogen as an indicator of physiological stress. We obtained 230 samples of foot tissue from Lampsilis cardium (n=118) and Lasmigona complanata (n=112) from a total of four rivers during September 1-5, 2015. From each sample, we weighed out
