Description Three dam operators on the Pend Oreille River monitored total dissolved gas (TDG) during mid-March through early August, 2001 through 2004. To fill data gaps and compare data between organizations, the Department of Ecology also monitored TDG during 2004 near Ruby and at the other monitoring stations.

TDG levels from upstream of Washington State and TDG generated by Box Canyon and Boundary Dams often exceed standards. The effect of natural processes on TDG is very small.

The TDG Total Maximum Daily Load (water cleanup plan) recommends allocations equivalent to 110% saturation at the 95th percentile low barometric pressure.
