It's also possible for turnover to occur in parts of the lake, but not the whole lake ... depending upon the size of the lake and the various different thermocline levels in that lake.
It's not so much "complicated" as it is "variable" ... doesn't happen all the time, on all bodies of water, but can & does happen for the same reasons : cold water at the surface, over warmer subsurface water, is denser (heavier) and will drop down thru the warmer water, mixing up the temps throughout the levels. The more the volume of water or depth of water involved, the more likely it will involve stirring up bottom sediment and causing discoloration of the water & the "smell" (from the decomposed plant/animal life that is in the bottom sediment).
I don't know as you'll have to worry about Taylorsville "turning over" just yet ... but, the lake is nearly 5ft above pool and rising, according to the COE chart, and that's gonna make it a bit messy for awhile.
