What is going on with Columbia River winter steelhead?

[Yard Sale]

Okay, what am I looking at? The dam numbers out east are crazy high. Here in Hood River we supposedly live on the furthest east winter run(I believe the Klick gets a run too), but the numbers over Bonneville pale in comparison to Dalles/JD and Ice Harbor/Granite is even more than those.

Are these summer fish that held in lower tribs rushing up to their home waters with spring rains? They can't be fresh winters because Bonneville hasn't had many fish at all this winter.

The Fish Passage Center (FPC) provides current and historic data on salmon and steelhead passage in the main stem Snake and Columbia river basins. Data from the Smolt Monitoring Program (SMP) is intended to provide the information basis for federal, state and tribal recommendations for fish...

Steelhead counts appear higher at Lower Granite Dam because most years a group which migrated into the river system between October and December overwinters below LGR and continues its migration in early March.

There are a good number of summer run fish that over winter in the Hanford area that destined for the Snake River basin to spawn.

On such I found a 2-salt fish that was hatched on the Lostine river, a tributary to the Wallowa, that spent two years at sea, over wintered in the Okanagan, and returned to the Wallowa in the spring to spawn. Remarkable!

There are summer fish that hang out in various parts of the Columbia and their tributaries that move to their spawning ground in the spring. Even the hatchery fish at Ringold in the Hanford Reach return to the collection pool in April.

We all get lost a time to two. Interesting!

Truly remarkable! If my count is right this fish ascended and crossed over nine dams to get to the Wallowa then over/through five dams going downstream and over four more to get to the Wallowa. Busy fish!
