What is legal in your area? In the USA, it is illegal to bait, but you can plant crops to attract ducks, dove, quail, pheasant and wild turkey. Is there woods or cropland adjacent to your pond site/
On our farm, I built an 8 acre pond in the woods, with a chimney spillway stack in the middle of the dam, feeding a 36 inch corrugated pipe. The front of his chimney is open, with 2 inch u-channel facing each other 24 inches apart. The channel is held together by welded rebar. Into this channel, I can drop stout oak or cypress boards, each with a steel bar backing behind it. There are sllots cut every 3 feet, so I can insert the boards without having tg climb to the top.
The deep end is planted in corn, standing about 9 feet tall,
Halfway back, is planted in milo, standing about 3 feet
The shallow end is planted in millet, which grows the shortest
We can shoot dove in late Summer and early Fall.
We can shoot deer and small game.
Then, about late September, we start flooding it, so the grains are just at the top of the water in some patches. By November, it is usually full of water, and ducks are starting to arrive from Canada.
