So the eggs were in the water? For more than 5 mminutes? They most likely have died. I had a goose nest washed out by flood water. The eggs didn´t actually stay in the water, but they still died. Water chills them very quickly, of course. You can try moving the nests to see if they´ll use them, maybe to lay another clutch, but it´s usually difficult to shift geese.
Geese tend to like the same spot, so it´d be good to make it either less attractive there, or make somewhere else more attractive. Of course, geese in their natural environment will nest in marshes, so she´s only doing what´s natural. Some geese, however, like to nest up high on a littel hillock, so I don´t know if you could get her interested in a nice quiet little spot that´s up a bit, with lots of grass etc around for her to hide in? If you move her, she may well nest again this year, you never know.
I put everything as close to her old nest as possible, but made it all nice and nesty, and each day I moved it a bit further away (in a tyre, it was easy to shift) until it was in a safe place. I used as much of her original nesting material as possible so she had her smell on it. (I´m sure they use their sense of smell, they can track me through tall grass!) Some folks find it easy to move their goose by blocking the old site and making a nice new nest with the old material in the desired place, some geese will accept it readily. Hope all goes well for you.
