I make a trip over there onoce a winter or so. Forty+ miles for me each way, so it is probably worth fishing, although I like road trips to different waters.
The yellows bass fishing is alright in the winter (I have never fished it on open water), although they don't run as large as they do on Clear Lake. Sometimes I get in to some nice bluegill, too. The crappie I have caught in Otter Creek have all been small.
I was told by somone over there that Otter Creek is on the lake reclamation list. If true, hopefully the panfishing would be better after the yellows are killed off.
