Check some other inland lakes with your traps. You will probably find a lake dwelling minnow/shiner. Any beaver ponds near you to trap? Another idea is to check with bait sellers for minnows. Especially check the bait sellers that collect their own minnows. They, a game warden or a college biology or fish squeezing professor may know of some lakes with natural minnow populations. Do some homework and you will find something.
