A pond in this category must be carefully oriented to any existing landscape and adjacent structures. In addition, cleanliness is probably a little more important than with an Informal pond. Informal ponds, in contrast to the formal ponds that are sculptured or geometric in concept, seem to be more relaxing. Informal ponds are often designed to emulate nature with waterfalls, streams, boulders and plant life. Complicated shapes should be avoided.
Simple shapes are easier to dig and the liner is easier to install as well.
Less liner will be needed, reducing the cost. The size of the pond will be determined by location on decks, patios, balconies or terraces. Even half a whiskey barrel or patio pond can be quite an impressive display with water lily, lotus, a few hyacinth and a couple of goldfish. There are greater possibilities with larger bodies of water, increased plant opportunities and water reflections. Larger bodies of water are also easier to maintain, have fewer temperature fluctuations, and can accommodate more varieties of plant and animal life.
