Re: Status Update for Fraser River Late-Run Summer Steelhead
The monitoring time frame for Interior Fraser Steelhead in the Albion test fisheries concluded on November 20. Catches over the entire monitoring time frame in 2019 suggest that Fraser River Late-Run Summer Steelhead stocks are at extremely low levels of abundance and in a state of Extreme Conservation Concern.

There is a 95% chance that the status will be classified as an Extreme Conservation once spawning population abundances are estimated in the spring of 2020. Conservation classifications are described in the Provincial Framework for Steelhead Management in
BC (2016) and supporting technical documents.

Fraser River Late-Run Summer Steelhead is a group of stocks comprised of 10 spatially discrete spawning stocks distributed in the Fraser watershed upstream of Hell’s Gate.
The aggregate commonly referred to as “Thompson and Chilcotin Steelhead” comprises 7 out of these 10 spawning stocks. The current spawning population forecast for the Thompson watershed is 134 and the current spawning population forecast for the Chilcotin watershed is 62. The forecast for the Thompson represents the lowest observed over a 43-year monitoring time frame. The forecast for the Chilcotin represents the lowest over a 49-year monitoring time frame.

Here's the update I got from Robert Bison - Provincial Steelhead Biologist:

Yes there is evidence that Chilcotin steelhead successfully passed the slide in November 2018 based on the abundance that we observed in the spring relative to what we expected to see based on the test fishery. Had the slide prevent upstream migration of Chilcotin fish, we should have estimated 30% less than what we forecasted. Instead we estimate quite a bit more than was forecasted. And we checked that the forecasting was not off be comparing forecasts to estimate in the Thompson.

This year, the water is higher than last year, so I’m not sure if Chilcotin fish will have more trouble this year.
