Rainbow spawn

If the browns on tany run in the autumn...when do the big rainbows make their spawning efforts?

December - February depending how long they have been in the lake. Although I've seen eggs in female trout later than February; must be due to the unique waters of Taneycomo.

After decades of trial and error, two primary strains of rainbow trout are now grown in our state-owned hatcheries and stocked in our state. These two strains are called the "Missouri Strain" and the "Missouri Arlee Strain". Yep, our state actually developed it's own strains. Cool, eh? The whole point of playing mother nature was to develop a strain of fish that grew quickly, was resistant to disease, and resilient to changing water conditions. The reason for two strains is to have a strain that will spawn in the autumn and another that will spawn in the springtime. This, of course, increases efficiency and yield from the hatcheries.

Wild rainbow trout in Missouri begin spawning in late December and
continue through the first week in February. This is approximately the same
spawning time period as that of their ancestors from the McCloud River in Cal-
ifornia. McCloud River rainbow trout originally spawned during spring when
water temperatures were increasing (Wales 1939, Breder and Rosen 1966), but the
mixing of different strains of rainbow trout has resulted in considerable var-
iation in the spawning period (Agersberg 1934). Hatchery broodstock descend-
ants from the McCloud strain rainbow trout presently spawn in October and
November because of intentional selection by hatcheries.
Wild rainbow trout spawning in Missouri is generally associated with a
day length of approximately 10 hours, decreasing water temperatures, and
minimum water temperatures lower than 50°F. Trout generally spawn after a
sharp reduction (at least 10°F) in the minimum water temperature

Rainbow trout typically spawn in the springtime, between February and May. As their eggs need cold and well-oxygenated water, the optimal water temperature range for their spawning is 40 to 55°F (4.5 to 10°C).

Wild trout in Ozark springs spawn in late December through early February; hatchery brood stock spawn in October and November.

So on Taney probably November December and then again in spring

A little more  looking turned up an older thread on this subject, and the good stuff from it-

Rainbows spawn in Taneycomo mainly in January and February but some spawn as late as May. When rainbows are raised in a hatchery, their biological time clocks are screwed up because the way they are raise. They are raised in varied water temps to stunt growth or to speed growth, depending on when they are sceduled to be released. So they really don't know when to spawn... but most do in the winter. Why? Not sure.

not all fish move to the dam to spawn... but alot of them do..

The brown is just starting to finish up.. there are still a few nice browns up but no massive browns...

Now the rainbows are moving in.. I think the bow come in after the brown to eat up the left over egg and chase the small fries..

the bows should spawn for about now till about mid Jan.. maybe early Feb..

It is weird how fixated on browns we are but just not quite as fixed on the big rainbows in Taney... interesting stuff and might warrant a trip in January if the water is off.

In my opinion, I prefer brown trout fishing over rainbows mainly due to the fact that they are more predatory in nature which to me makes them more exciting to fish for and to catch. That being said, I will never turn down the opportunity to catch big rainbows 😉.

More exciting to fish for ?  

Browns fight like a channel cat 🙄  At least Rainbows take to the air occasionally.

Browns will attack a much larger bait than a rainbow and absolutely maul it.  Rainbows seem to just come tight.  But after that I agree, rainbows go spastic whereas browns “ generally” dog it.  But last year during the spill gates I had several browns tail walk it.    Both of these 25” plus
