Decide on the Shape of the Pond
When you begin the design process, and after you've sketched out your basic design, use a garden hose laid out on the ground to experiment with the size and shape of your water garden. Our overall pond design calls for a shape that is roughly oval, with basic dimensions of 12 feet long and 10 feet wide. The depth is 18 inches at one end, sloping down to 24 inches at the other end. The skimmer is located at the shallow end, and the waterfall at the deeper end. The berm will provide a good backdrop for landscaping behind the pond and for creating the illusion that the cascade of the waterfall flows from a stream. As you decide on the size of your pond, be sure to take into consideration the rocks and aquatic plants you'll be adding later. Another common mistake among beginners is building a pond that seems big enough at first, but then appears too small once the rocks and plants are added.
