You may not be able to afford a house at the lake, but that doesn't mean you can't bring some sounds of the lake to your back yard. Water features in the form of fountains are popular for outdoor spaces, but why not do one better than that? If you want to add a little wow, consider adding a koi pond, waterfall or stream to your landscape. Large scale plans like this may not fit into your budget, but choosing one on a smaller scale that comes in a kit may allow you to put your DIY skills to the test and create a focal point for your family to enjoy during their leisure time outside. Fish not included.
