All three of the creeks have your typical mix of Susky watershed WW fish...Smallmouth, Fallfish, Rock Bass, Sunfish (mostly Redbreasts), and the occasional Walleye or Muskie in their lower reaches maybe.
How they fish is all habitat dependent. Where there's habitat they can all fish good. Where there's not, you're in for a long Summertime walk with wet feet, carrying a long pole. They take time and some exploration/trial and error on different stretches to figure out where they'll fish well. Summer is a good time to do this, since many Trout waters are warm and/or low and don't fish very well. They all merit exploration if you're willing to put in some time and don't mind striking out a bit to find the good water.
Have no clue about the lake.
