We could start by mentioning that our habitat restoration and fish passage improvement projects are delivering big results in some of the last best wild steelhead strongholds in North America.

Steelhead 101: Using weirs to estimate adult steelhead escapement

Rather than sending out surveyors to sample stretches of stream where they count redds or fish, the operation of a weir is much simpler. A weir basically blocks the river and …
