The overlying water chemistry data were collected to verify that acceptable test conditions for H. azteca existed during the sediment exposures. The sediment exposure data will be used along with bathymetric and biotic data collected by USEPA in a risk-assessment package assembled by the Georgia Environmental Protection Agency for presentation to the US Corps of Engineers as part of the permit process to breach the dam. The Ha Weights data are dry weights of amphipods surviving at the termination of sediment-toxicity assessment were determined to evaluate growth during sediment exposures. The sediment characteristics data are physical characteristics of the sediments including moisture and organic contents along with proportions of sand, silt, and clay were determined to aid in evaluations of sediment toxicity.
