Summer vs. Winter

by David Johnson


It is transition time in our steelhead rivers. Summer run steelies start to trickle in, mixing with the winters and eventually the winters fade. Both can be caught now through April.

I've already heard of several summers caught from the Sandy and Siletz and I'm sure there have been some caught from the Clackamas too.

But how do you tell what you have?

Some of the key differences you can look for in an early summer are the very steel blue back, white belly and very clear fins. These clear fins will have a blue tint to them when the fish is still swimming in the water. Their body/belly will also feel solid. Many of the late winter steelhead, both hatchery and wild, will be as chrome bright as an early summer and could be hard to tell apart. If it is a hen, look at the vent to see if it is protruding. Its belly should feel loaded with eggs (because they will be) if it's a buck it may have just the very lightest tint of rose in the cheek.

Late winter (caught on coastal river April 28)


Now these features can sometimes be very slight and the only 100% way will be to clean it and see how undeveloped the eggs or sperm are.


Size difference of the eggs in summers and winters


Another steelhead you may come across is a spawned out winter. These might have "trouty" colors or some may be hens that are bright. Tail erosion, a small concave line down the belly and a "snakey" appearance are tell tale signs. These spawned out fish should be released as they are usually poor on the table and will return another year if they get the chance.


Notice that the belly is skinny and not full


It's an exciting time to be on our rivers, chasing a mixed bag.

Nice informative article! My earliest "summer" on the Wilson was on a March l8th quite some years ago -- that's like day after tomorrow!

Nice pictures, and great information David!

The one drawback is all the spawned fish you hook vs the late winters and early summers. You beat em up a little bit more and it makes you cringe. That's why some people give them a break. How many of those fish will make it another cycle?

The spawners only make up a small percentage of the fish we catch this time of year, only caught 5 this winter- a couple of those were back in January, a couple last week and one in Feb.

I believe studies are going to start to show that on the coast a good number of the fish make more than one spawning run.

So I bagged one the other day and thought for sure it was a winter. Fat with eggs. However, the marking of fins was wrong for this hatchery fish based on what I have read. I hooked 3 that day, all chrome. This one had an adipose clip, but I think this is a summer marking? It should have also had a left maxillary clip.

So what did you find inside when you cleaned it JimShady?
