A Sanitary District is having issues with an increasing geese population at one of the treatment plants. These geese are no longer migrating and there is concern about the public health impact. Furthermore it is located within urban area with firearm restrictions.

Any advice or suggestions for them?

Yep, run around on it in a boat

One of our local parks was over run with geese. They brought in a pair of swans. The geese are now ALL gone from the park.
