Thomasm: i do fish the south end but rarely in the summer due to it being shallower... if anywhere near the marina,and the creek that flows into Wonder. The dam has lots of structure ( boulders ) near the rip rap side. Along with it being 10'+ in areas. Dunno if you know bout the fish cribs near it. If you dont lemme know will pm you with coordinates. Wonder has northern in it, not many, have been bitten off bass fishing sometimes.
Ps. Also found a GOOD piece of structure like i stated a few posts ago.. dont think anyone knows it, north end, been fishing 30+years didnt even know it was there,found it this spring LOL thank God for Lowrance :)
Do you have ice fish?
