Curt, I am no biologist. However, I have made a few observations below dams that sometimes are forgotten. Do these observations apply to "run of the river" projects as well?

Let me know if I am off base:

Any dam will stop the natural flow of gravel to the spawning beds. For example the S. Fork Tolt; the only remaining native summer run steelhead in the snoqualmie system are starving for gravel to spawn on. This is due to the fact that these fish only spawn above the forks and only in the S Fork. Some years we have seen as low as 60 spawning pairs left in this system.

According to the the King County Snoqualmie/Skykomish watershed forum high water temperature is a major concern of this system. How much effect does a run of the river dam have on water temp? My guess is that more water surface area and discharge levels would increase water temp.

What are some of the other effects of this proposed dam on the Sky?

I signed the petition and hope to again enjoy steelhead fishing in march on the SKY in my lifetime!
