1Adult Returns to Lower Granite Dam data from Fish Passage Center


Total Dissolved Gas in Lower Snake River reservoirs is often high during juvenile Sockeye migration.

Note: TDG > 125% for prolonged periods is considered damaging to salmonids.
Source: ACOE Data Query

High Total Dissolved Gas exceedances at Lower Granite Dam tailrace often coincides with juvenile Sockeye migration

High Total Dissolved Gas exceedances at Little Goose Dam tailrace often coincides with juvenile Sockeye migration

High Total Dissolved Gas exceedances at Lower Monumental Dam tailrace often coincides with juvenile Sockeye migration
