Remove the eggs and hand pick any snail that you see.
Your pond is rather large though!

Snail killing chemical treatments will harm other living critters in
the
pond.

You can make a snail trap, fill a bucket with lettuce and algae wafers,
suspend in the pond in the evening, by morning, hopefully you will have
caught a bunch of snails.

Most folks do preventive treatments of plants they put
in the pond, as many snails sneak in this way, very small or
as eggs. A weak solution of bleach will work, soak
the plant for 24 hours. Someone have a ratio of bleach
to water? Some folks use potassium permanganate
soaks but that stuff scares me!

Be far more scared of bleach than potassium permanganate (PP). PP is a
much milder oxidizer than bleach, is easier on the plants, and even fish
can tolerate moderate amounts of it. It's also colored, so you can see
how strong your solution is, and when it's gone. To kill nasties on
plants, make a pink solution - fucshia (sp?) is too strong and purple
WAY too strong, and soak them for 10 minutes. Rinse well, and into the
pond they go. I do this for fishtanks all the time.
