Our first pond build is taking shape. This is a 300 gallon buried stock tank pond with a slightly raised bog filter approximately 24% the area of the pond and a small waterfall. No fish at the moment; we may add some very small ones next year, when things are more established. Still needs a lot of finessing, but all the fundamentals are there. Thanks again to everyone for their advice! We're totally new to water gardening so we still have lots to learn. I'm sure the adventures are just beginning...
