Utah Lake - Summer Fishing

[Joe_Dizzy]

Question for those that frequent Utah Lake during summer… I was looking for local “warmwater” options to get my float tube out in the evenings (quick trips) and portions of Utah Lake are close enough to fit this description. However, before I get myself into trouble (maybe a violation in etiquette):

Is floating/fishing in, and around, the boat harbors acceptable… or would I be “in the way” and strongly discouraged?
 
And while I am at it… are the harbors worth fishing at all during summer?
 
I would be strictly targeting panfish with the fly rod.
