We have set lines in farm ponds for them on occasion. Get yourself some stakes and and nylon cord. Wire on some big hooks. We always used wire for the last 18" or so so they couldn't bite the line off.
Bait with beef heart or other cheap meat. Toss them out into the water with the stake pounded in as deep as you can from the edge. Check daily or so.
