I finally got around to digging my pond this past weekend. It is about a 30 ft by 17 ft hole. the deepest part is about 4 ft but I am going to put some fill sand to raise it back up to about 3 ft. The deep end runs straight up to the gazebo so I can feed my koi from the standing way. The shelf all around is 16" deep and it is also the same depth on the shallow side. I plan on making the shallow side a bog and by putting a big piece of wood under the liner to hold the sand in. There will be a waterfall on the back part of the shallow end where it has the straight line. The waterfall will look through everything right up to the house, so it is the first thing you see from the pond when you look out between the pool and gazebo. Also there will be a stream that runs to the pond between the gazebo and pool, with a little abridge going over it. There will be a waterfall next to the house where it all starts. The liner is already in the mail. Im so excited to get it going. Pics!
