Laser ablation inductively coupled mass spectrometry was used to quantify Strontium:Calcium of the core of each otolith and classified each fish to a natal origin (i.e., tributary or potential resident). Predator fishes of focus were Bowfin and Largemouth Bass from the Upper Mississippi River (Pools 4, 8, and 13). Any use of trade, firm, or product names is for descriptive purposes only...

Observations and subtle shifts of aquatic vegetation communities in Lake Erie have USGS researchers concerned about the potential for grass carp and other threats to alter these vegetation communities. Assessing submersed aquatic vegetation (SAV) may contribute to inform the long-term impacts of grass carp, common carp, eutrophication, wind fetch and sedimentation on SAV communities...

An eDNA-based sampling approach used by the U.S. Fish and Wildlife Service for bigheaded carp Hypophthalmichthys spp. in the upper Mississippi River and Great Lakes Basins that collects hundreds of water samples per event. The U.S. Fish and Wildlife Service detected a single positive sample for bighead carp _H. nobilis_ during the spring 2021 sampling event in the Kinnickinnic River...

To address how phytoplankton in the Great Lakes respond to macro- and micronutrients, we conducted a bottle incubation enrichment experiment using water collected from blooming (Maumee Bay and Fox River) and non-blooming sites (Detroit River and Ford River) in Lakes Erie and Michigan, respectively, during late summer. Surface water from these locations was collected and taken to Kent...

Acoustic telemetry data (Innovasea, Inc.) were collected on invasive Silver Carp (Hypophthalmichthys molitrix) in the lower reaches of the Tennessee and Cumberland river systems to determine timing and environmental conditions associated with dam passages by Silver Carp during 2016–2019. Data also include water level. dam discharge, and lock use data for three dams within these river...

This release contains data collected to study surface-groundwater interactions during flood events in the floodplain of a restored reach of Underwood Creek in Wauwatosa, WI. Continuous floodplain sediment temperature data was collected at 6 sites from May 2018 to October 2021. Temperature data was used in conjunction with soil thermal property measurements and published groundwater...

Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’ (SS) to a nearby beach. This pile of SS has migrated via wind and rain along the beaches in northern Grand Traverse Bay and into Buffalo Reef, an important spawning area for Lake Trout and Lake...

These data and code were collected to support the development of a modeling framework that integrates local daily weather conditions and land cover with individual energetics and morphology to simulate mallard (Anas platyrhynchos) and northern pintail (Anas acuta) migration across the Northern Hemisphere.The simulated birds move across a discretized landscape of 20 by 20 mile nodes...

This dataset contains predictions of habitat suitability of reed canarygrass (Phalaris arundinacea) in Upper Mississippi River floodplain forest understories from Pool 3 to Pool 13. Predictions were created using three machine learning algorithms (Bayesian additive regression trees, boosted trees, and random forest). This dataset contains rasters that provide habitat suitability...

Lake water level fluctuations are an important factor driving variation in many ecosystem processes. The nearshore sediments that are periodically exposed and re-inundated can develop distinct physical and chemical characteristics, especially in relationship to the organic matter content of the sediments and the particle size distribution. These sediment characteristics in turn can alter...

We evaluated the efficacy of carbon dioxide (CO2) for preventing settlement of the biofouling quagga mussel (Dreissena bugensis) in raw water systems. Trials were conducted in a mobile laboratory located at the US Bureau of Reclamation, Davis Dam Hydropower Facility, and supplied with raw water from the Colorado River. Incoming water was split between five chambers where CO2 was...

Detection of environmental DNA (eDNA) has become a commonly used surveillance method for threatened or invasive vertebrates in both aquatic and terrestrial environments. However, use of eDNA methodologies for the detection of aquatic invertebrates (e.g., crayfish and insects) has been limited. Environmental DNA protocols can be especially useful for endangered invertebrates such as the...
