Ive done some research and have red that the fish don't start spawning till at earliest February but I hear a lot of talk of fish already dropping eggs and I caught a hen today that was real lean and looks like she was a drop back in the spring  Do they drop eggs in fall? Just curious to try and educate myself more on this amazing fish.

Many steelhead and brown trout have been spawning now to my surprise as well.

Some hatchery fish (esp. US fish) are ripe in early winter. Its not natural, they've been created that way in the hatchery by breeding for early spawning fish.

Steelhead are an amazing species. Several different strains are fall/winter spawners. Hatchery breeding may have something to do with fish that are spawning in fall/winter but it is more likely the hatchery is using a strain of steelhead that was a fall/winter spawner. Bc has several strains of fall/winter spawning fish. Steelhead have been adapting to our rivers over time and several differences exist between fish running rivers based on what they face in each individual river. A good example is the Credit having such an extreme gradient over the length of the river the fish that are natural production in the river are longer and leaner than East Ditch creeks. They were at one point all from the same strain but signifacnt advantages over time from individuals in each population have differentiated the populations in ways which suit the river they run. Not all Steelhead even return to the river they originate from. A small portion of the population of each river roam to run a different river. In this way they can spread to new rivers. Truly a diverse and amazing fish.

Couldnt have said it better... I will also add that the bulk of spawning activity happens with water temperature from around 40*F-58*F, and independant studies have shown the colder the water the higher chance of success. But then you look at the skamania strain of steelhead which enter creeks in the middle of summer when water temps could be over 80*... I doubt we will ever fully understand them.

80 degrees is a bit extreme. Rivers or creeks in the middle of summer months I don’t think so. Shallow lakes and ponds possible.

If you frequent East further than BMV..the strain is somehow similar (in appearance to the Credit & Bronte strain).

There are multiple strains in every river. My local has like 19 distinct strains

There's a reason Skamania didn't last in Ontario... they enter rivers during the worst possible time for spawning. High temps and low flows. I believe most successful spawning also takes places through the winter.

"could be over 80*"
