| Description | This Total Maximum Daily Load (TMDL) addresses total dissolved gas (TDG) in the Snake River from Idaho to the Columbia River. Elevated TDG levels, which can cause "gas bubble trauma" in fish, are caused by spills at four dams. Loading capacities and load allocations are set in terms of (1) percent saturation for fish passage conditions, and (2) excess pressure above ambient during non-fish passage conditions. Allocations must be met below each dam at a specific distance below the spillway (near the end of the aerated zone). The implementation plan describes short-term and long-term compliance with both Endangered Species Act and TMDL requirements. | ||||
