California Guiding (day trips)

I'm hoping to garner some personal insights with regards to what a season looks like in Kernville and in Coloma.

Specifically:

-Do I understand correctly that the dam release sections of each of these rivers remain runnable, and the season viable, through August in both locations?

-How cold is it?

I've guided two Ocoee middle section seasons (class III). Had a blast on the water there and very much look forward to similar fun elsewhere. I have found though that I'm fairly fair-weather oriented, not particularly interested in a lot of big icy gnar at this point, and I'm certainly not equipped for it (no drysuit etc).

It seems as though both of the dam released sections I mentioned should provide that Summer-fun vibe I'm looking to get into. As a relatively new guide who can't really dictate their destiny and could reasonably expect to see some snow melt in the Spring, even if only for training, how much consideration should one put into equipping themself for those conditions early on? I see that Coloma is a big spot for trainees, and can't really imagine those kids are all showing up with wetsuits etc. Guess I'm kinda wondering how requisite additional gear would be for a guide moving to West from East, with no experience around snow melt.

Any general input you have regarding the two towns would be appreciated. I like the scenery in both places, erring a bit to the SoCal desert. On the other hand, the Coloma region is gorgeous as well, and it seems perhaps a little less volatile in terms of water availability and business volume. ?

Thanks much for your time and input.
