Intro
No matter what style of landscape you have -- or are considering -- there's a style of pond and fountain that can complement it. Installing your own pond and fountain may seem like a formidable task, and it does involve some physical labor, but it's a project well within the capabilities of most homeowners. Besides, much of the labor makes an excellent excuse for a pond-building party. Before you get the shovels out, however, you'll need to do some planning.
Location
Where you put the pond depends on a number of factors. First consider the general terrain. You'll want to stay away from slopes, unless you plan to turn them into waterfalls. Soil conditions matter, too. Rocky soil will make excavation difficult and may call for an aboveground pond. Sandy soil may not be stable and could require a preformed liner. Clay, though difficult to dig in, holds its shape and is excellent for flexible liners. How the sun hits your location will affect fish, plantings, and even how you use the pond. And while you'll want easy access to this water feature, you may want it somewhat hidden from view so it provides a private retreat. How you want to use the pond will have as much to do with its location as any other feature. On an entirely practical level, however, the installation of a fountain in conjunction with the pond means you'll either have to locate it fairly close to an existing power source or bring the electric power to it through an underground conduit.
Design
Because flexible liners fold into and follow the shape of the excavation, you can design your pond in whatever shape and contour you want. Even if you decide to install a preformed liner, you'll find modern designs can match most every expectation. You'll want to consider the scale of your pond, making sure it neither overpowers your yard nor disappears in a large space. And, as much as possible, you'll want to choose edging that makes this artificial creation look as if nature put it there without your help.
Plants and Fish
Plants add color, shape, and texture to a pond and make it fit more naturally into the landscape. If you want plants, your pond location needs to get four or more hours of sunlight each day -- and you need to be willing to tend to the plants. Fish also add movement, color, and a touch of the exotic to a pond, and they help control the mosquito population. They also require extra care and, in cold climates, the ability to overwinter them in another location.
All of these factors will affect your design, something best done with a sketch on paper. If you don't have a site plan of your landscape, you can make your own, showing all the permanent features of your yard, including the general shape of your house, as well as the location of trees, sheds, and planting beds. Experiment with general shapes that seem pleasing in the location you are planning. If you're thinking about plants and fish, you'll have to do some research about their appropriate depths and incorporate that into your final design.
