I asked a MDC fisheries biologist about spawning bass in Taney and this was his comments-
Generally speaking, smallmouth will spawn around 57-64 degrees, and largemouth will spawn around 60-72 degrees. Taneycomo is a little different though. It seems that the bass spawn in Taneycomo is more affected by the length of daylight hours than water temperature. For example, we sampled Taneycomo on May 19, 2008 when the water temperature was about 59 degrees and we saw largemouth spawning everywhere. In 2009 we sampled about a week earlier, water temperature was around 58 degrees and only saw about a fourth of what we saw in 2008. The vegetation wasn’t growing yet and the fish just weren’t on the beds. In 2008, the vegetation was growing very well and they were on beds all around the shoreline. In our samples, the water temperature was much warmer in Bull Creek than the main lake, and I think that makes a difference on timing of the spawn to some degree. Can’t say for positive sure though because when we were there, the water clarity was a lot worse, making it more difficult to see fish. We did sample one largemouth that measured 22.5 inches in 2009, it weighed about 7 pounds. Caught it on the main lake south of Rockaway.
We usually wait for the water temperature in Table Rock to reach 60 degrees before we start sampling. I think you could safely say that the bass will spawn in Taneycomo about 2-3 weeks after the bass in Table Rock. If the water temperature never gets warm enough, they will go by length of daylight.
Smallmouth tend to spawn in more rocky, gravelly substrate, vs. largemouth that prefer woody cover and silty substrate. I think that’s why we get such good largemouth recruitment in Table Rock during high water years (i.e. 2008). Lots of woody cover (buttonbush) and more silt to spawn around when the water is high. It seems to be the trend that we’ll get good smallmouth recruitment during lower water years and better largemouth recruitment during high water years.
We found largemouth spawning in coves by Powersite, in the main lake south of Rockaway Beach, and in Bull Creek. All of the suitable habitat is there in the entire lower lake for the largemouth to spawn. I can’t say for sure about where the smallmouth spawn because our electrofishing gear isn’t effective in capturing smallmouth (they’re usually too deep). I do know that there is an excellent population of smallmouth in Bull Creek, and some nice ones too. Just go wading where the lake turns to creek sometime in the summer and you’ll see them. I have to imagine that those fish use Taneycomo as well. I suspect they spawn more up the creek arms in the lower lake, and if that is the case, there’s plenty of suitable habitat for them there. They may also spawn deep in the main lake, but if they do, we’d never see them in our samples. We don’t even see many smallmouth in Table Rock when we sample, they just stay too deep.
