Welcome Waterbug. We welcome your questions. Being in NW Ohio, you are surrounded by a lot of great experts here on the forum. We've got a lot of members in Ohio, Michigan, Indiana, and Illinois. Actually, those of us in WV and PA have pretty similar weather and water conditions also.
Make sure your fatheads have a place to party so they will reproduce at a maximum rate. They spawn "upside down" so they are looking for things above them to do their work. I've found that 6x8 inch colored foam craft pads, available in craft stores for about 50 for $4.99 are excellent for this purpose. I've tied strings of them together, and tied a small sinker to one end, and the other end to the bank. They seem to work great.
Don't be afraid to ask questions. And, tell us a little more about what you've got, and about your plans for the pond.
Regards,
Ken
So, how small is your "small backyard pond?"
