Mercury Concentrations in Bald Eagle Feathers, Bad River Watershed, Wisconsin, 2014-2016

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 e

Mercury Concentrations in Litterfall, Bad River Watershed, Wisconsin, 2012-2018

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

Daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary for the years 1950 through 2015

This USGS data release contains daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary. Estimates are provided for the available period of record of streamflow data at each site between 1950 and 2015. A two-parameter recursive digital filter was used to estimate baseflow at the selected...
