Know the problem well: we live on a small lake. Even without feeding them & despite my two dogs best efforts, we have quite a poop problem. It is especially bad in the Winter since the dogs can't get out to the dock without swimming 50 ft or so. Goose population grew over 10 years from a dozen up to 96. Then 2 Summers ago, the County trapped & gassed at lakes around the area. We are back to 15 or so, the local food missions served goose & the situation is much improved. Lately, a couple eagles in the area help keep the population in balance.
