Put in the largest pond you can afford. If you don't you'll
be adding another one next year. Also, read all the books
you can put your hands on, Helen Nash's Low-Maintence Water
Garden and The Complete Pond Builder are two good books
-there are many others.
K30a will have a list of sites to visit.

I have to agree with Bonnie. We started out with two preformed ponds of a few
hundred gallons and within two years we built a 3500 gallon one. One thing to
make sure you do is to plan ahead for your plantings. We ended up improvising
after finishing the pond by using bricks and milk crates to prop up the plants
to a level that's happy for them and to accomodate layers of plantings.
