Mtn,
I agree with Sunil, try to capture & identify the minnows. If you are considering SMB read the posts under Types of Fish To Choose SMB in a 3 ac. pond by TYW33. Very intresting topic reguarding SMB & BG. If that raises your intrest search for posts by lakedoctor reguarding SMB.
I don't know why lakedoctor hasn't posted lately but he had extensive experience on the subject of SMB & contributed greatly to this forum. I miss him alot!
Anyway I get the feeling you haven't completely decided on your end goal with the pond and I would suggest reading up on SMB. Anyone can have a LMB pond especially if they listen to the instructions from the experts on this forum & purchase the lit from Pond Boss which by the way is a really smart investment!
I'm stocking trout with a back-up plan for SMB if it doesn't work out. I can go to any body of water around me & catch LMB. I have nothing against LMB .. love to catch them, but have always wanted to catch a very large trout or SMB. So .. I'm going to grow my own!!!
Keep giving info as to what you have & read on here as much as you can which should cultivate some pointed questions. Post them on here .. there is ALOT of experience here!
For myself .. I'm very thankful I found this site!
