These data represent mercury (Hg), filtered total Hg (FTHg), filtered methylmercury (FMHg), particulate total Hg (PTHg), particulate methylmercury (PMHg), total mercury (THg), dissolved organic carbon (DOC) and total organic carbon (TOC) concentrations in surface water samples collected on Bad River Tribal lands. Several samples were collected at multiple locations on the Bad River and Tyler Forks Creek, and one location on Bull Gus Creek. Additionally, one sample was collected at each of four unknown locations on four Bad River tributaries and two samples at a lake of unknown location. All samples were collected during 2006 to 2016. Neither the collection of water samples nor the Hg analyses were performed by the...

Annual litterfall samples were collected and analyzed for THg (total mercury) and MHg (methyl mercury) at a site (WI95) on Bad River tribal lands during 2012 to 2018. Litterfall was collected at a second site, WI01, during 2012 only. Litterfall was sampled in eight collectors, from which annual mass was determined. Total mercury analyses were performed on only four samples from the collectors with the lowest numbers in the sequence. A mass weighted sample based on the four THg samples was analyzed for MHg. Neither the collection of litterfall samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

The breast feathers of 13 bald eagles were collected at 11 locations during 2014 to 2016 along rivers and sloughs on or near to Bad River tribal lands and analyzed for total mercury (Hg) concentrations. An age (7 - 9 weeks) was indicated for only two of the eagle feather samples. The eagle feathers sampled were likely all from nestlings, but this could be confirmed for only two of the eagles. Neither the collection of feather samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

These data represent total mercury (Hg) concentrations and percent organic carbon in bed sediment from 51 samples collected at 44 location in streams and rivers during 2006 to 2015 within or near to Bad River Tribal lands. Reach lengths are provided when they were available, and the data set includes sieved, unsieved, and samples where sieving status was not indicated. Samples were collected by the U.S. Geological Survey, jointly by the U.S. Geological Survey and Great Lakes Indian Fish and Wildlife Commission, or unknown collection agency. Neither bed sediment sample collection nor Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

These data represent Hg concentrations in tissue of 18 green frogs from the Bad River, Wisconsin. Neither the collection of green frogs nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

These data represent Hg concentrations in tissue from 104 analyses of fish samples collected at 7 sites in streams/rivers and lakes during 2004 to 2013 within or near to Bad River Tribal lands. Nine fish species are represented in this dataset. Most fish specimens were collected by the Bad River Tribe, but collection agency was not always indicated in source files.

Seven wild rice samples were collected in 2006 in or near to Bad River tribal lands and analyzed for methyl Hg. Neither the collection of wild rice samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

File represents total mercury (THg) concentrations in hair of nine river otters from the Bad River. Neither the collection of river otter hair samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center
