Streams in the northeastern U.S. receive mercury (Hg) in varying proportions from atmospheric deposition and legacy point sources, making it difficult to attribute shifts in fish concentrations directly back to changes in Hg source management. Mercury stable isotope tracers were utilized to relate sources of Hg to co-located fish and bed sediments...

Editor’s note: this news release will be updated online with more information on the streamgage records being set in Texas as it becomes available.
Rivers and streams reached record levels as a result of Hurricane Harvey’s rainfall, with about 40 U.S. Geological Survey streamgages measuring record peaks.
As Harvey’s record breaking rainfall and catastrophic flood waters recede in Texas and western Louisiana, U.S. Geological Survey teams are collecting high water marks, monitoring water levels and coastal change, retrieving storm tide sensors and collecting samples for water quality analysis.
