This study deployed acoustic telemetry at the Fox River Navigational System Authority (FRNSA) in lock #2 and the upstream and downstream pools in Kaukauna, WI to document movements and behavior of telemetered fish species in response to injection of carbon dioxide. Telemetry equipment was setup in the test area for approximately 2 months during the summer of 2019. CSV metadata includes telemetry data with position estimates for fish during this time.

Lead and zinc were mined in the Tri-State Mining District (TSMD) of southwest Missouri, northeast Oklahoma, and southeast Kansas for more than 100 years. The effects of mining on the landscape are still evident, nearly 50 years after the last mine ceased operation. The legacies of mining are the mine waste and discharge of groundwater from underground mines. The mine-waste piles and underground mines are continuous sources of trace metals (primarily lead, zinc, and cadmium) to the streams that drain the TSMD. Many previous studies characterized the horizontal extent of mine-waste contamination in streams but little information exists on the depth of mine-waste contamination in these streams. Characterizing the vertical...

Locks and dams are possible management points to block the spread of invasive Asian carps in the United States. Infusion of carbon dioxide (CO2) into water is one deterrent strategy being considered at navigational structures to reduce upstream fish passage that would not directly interfere with lock and dam operations. The goal of this study was to determine the efficacy of CO2 as a behavioral deterrent to free-swimming fishes. Telemetered bighead carp (Hypophthalmichthys nobilis) and grass carp (Ctenopharyngodon idella) were monitored within a U-shaped pond (30.5 m long x 13.7 m wide x 1 m deep) using a two-dimensional acoustic telemetry array. Gaseous CO2 was administered to one-half of the pond at 30, 75, or...

Concentrations of major and trace elements as determined by chemical analysis of the less than 2-millimeter size fraction of bed-sediment and floodplain samples in the Tri-State Mining District, 2011-12. All samples were collected by the U.S. Geological Survey. Analysis was conducted by the USGS Central Mineral and Environmental Resources Science Center laboratory in Denver, Colorado using inductively coupled plasma-atomic emission spectrometry and inductively coupled plasma-mass spectrometry methods described in Taggart (2002) as referenced in the associated report. Table Contents: Core_identifier, Depth_1, Depth_2, Site_Identifier, Arsenic, Cadmium, Barium, Cobalt, Copper, Nickel, Magnesium, Lead, Zinc, Aluminum,...
