Walker Branch Watershed: Weekly Stream Water Chemistry

This data set reports weekly stream water chemistry in the West and East Forks of Walker Branch Watershed (WBW). The long-term Walker Branch stream chemistry monitoring is intended to provide data on watershed output of chemicals via streamflow and long-term changes in stream chemical composition. This data set contains two data files of stream water chemistry collected at weekly time intervals from 1989 through 2013. Weekly sampling of stream water started in 1989 in the West Fork and in 1995 in the East Fork. Measured parameters include water level at the weir and stream discharge, water temperature, specific conductivity, pH, alkalinity, and dissolved organic carbon (DOC), soluble reactive phosphorus (SRP), total dissolved phosphorus (TDP), ammonium-N, nitrate+nitrite-N, total dissolved nitrogen (TDN), anion (chloride and sulfate), and cation and trace metal (calcium, magnesium, sodium, potassium, iron, manganese, silicon, aluminum, barium, cadmium, nickel, lead, strontium, zinc, copper, molybdenum) concentrations. The Walker Branch Watershed is located on the U.S. Department of Energy’s Oak Ridge Reservation in eastern Tennessee.
