The answer to the question about fry planting steelhead is out there. The Game Department, at Snow Creek, did a multi-year study where they looked at standing stock of fish in 3 creeks in spring, summer, and fall. After getting the background data the streams were fry-planted. Sampling continued, including smolt trapping. The streams were also spawner-surveyed, so there is a measure of what the natural escapement was.

Never have seen a write-up but the data was collected.
