Summary
Abstract: Excessive total dissolved gas pressure can cause gas-bubble trauma in fish
downstream from dams on the Columbia River. In cooperation with the U.S. Army
Corps of Engineers, the U.S. Geological Survey collected data on total
dissolved gas pressure, barometric pressure, water temperature, and probe depth
at eight stations on the lower Columbia River from the John Day forebay (river
mile 215.6) to ... View entire text

Quality Duplicate data for John Day tailwater were collected for TDG only. Data
between the two instruments compared well, as depicted on figure 12 in Tanner
and Johnston, 2001, which shows how the two probes responded to daily changes
in spill at the John Day Dam. The greatest differences occurred at times when
gas levels changed rapidly, as a result of ... View entire text
