Please educate me!! When it's said "managed" what are we talking about exactly? With the already cold outflow, stockings, typical regulations, and stream habitat - all of which seem fairly obvious, what exactly more are we talking about??
Dams are usually built for one of three reasons: flood control, water supply, or hydroelectric generation.
And none of those functions really need to involve supplying cold water below for trout fishing.
So - just because a dam is high enough to supply cold water all season long from it's depths, doesn't necessarily mean that it happens that way.
Water can be released from the upper levels of the reservoir - where its warmer, and doesn't help the trout fishery very much.
Raystown and Kinzua dams are good examples of this.
Timing of the cold water releases through the hot summer months - when it's really needed for a good trout fishery below - is also crucial.
And that is the kind of "management" that trout fishermen hope for
