- Abstract:
- Dissolved gas supersaturation in the Columbia and Snake rivers routinely occurs during the spring and summer freshet as a result of water spilling over dams and can be lethal to fish. Measurable plumes of high dissolved gas extend downstream of dam spillways and create gas supersaturated conditions that do not equilibrate in reservoirs. Based on modeling results, the extent of the dissolved gas plume downstream from Bonneville Dam before dissipating is at least 10 km and the lateral position of the plume is highly dependent on dam powerhouse operation and spill volume.
