You really want to be trapping before the ponds ice over. It can be done thru the ice, but generally even the shiners slow down (vs. late fall).
Like mikez said, you want small ponds or beaver ponds or fire ponds or damned up streams w/ low flow (some flow is OK, even good - but not raging current). Anything that doesn't dry up in summer can be good.
Try 3 or 4 near you next fall, I bet you find a good 1. Just need to put in a little time + effort.
