Rain gardens are landscaped depressions in your yard or on your property that are designed to capture stormwater flow from roofs, driveways, and other hard surfaces and filter it into the ground, away from the Lake.
By collecting water and allowing it to slowly soak into the ground, rain gardens reduce the potential for erosion and minimize the amount of pollutants flowing from your lawn into a storm drain, and eventually into Lake George and the brooks and streams that feed the Lake. Planting your rain garden with native plants not only enhances the beauty of your yard, but also provides valuable habitat for birds and butterflies.
Rain gardens are beneficial because they:
- Help keep water clean by filtering stormwater runoff before it enters local waterways;
- Help alleviate problems with flooding and drainage;
- Enhance the beauty of yards and communities;
- Provide habitat and food for wildlife like birds and butterflies;
- Reduce the need for expensive stormwater treatment structures in your community.

Creating a Protective Rain Garden
The first step is sizing and siting your rain garden. You want to pick a location on your property that you can direct a downspout or other source of runoff to, is at least ten feet from your home’s foundation, and is flat or gently sloping. A typical homeowner rain garden is around 100 – 300 square feet in area and four to eight inches deep. Just how big your rain garden should be will depend on your soils, slope, and the size of the area that drains to the garden.
Time to Dig!
After you have planned out your garden size, shape, and location, it is time to start digging. You can use a hose, string, or spray paint to outline the shape of your garden. As you dig, use the soil you remove to create the berm around three sides of your garden to hold in the water. The fourth side isn’t built up because that is where the water flows in. You want the bottom of your garden to be level. You can eyeball it – or get out a level to be sure.
Planting the Garden
Since a rain garden is flooded periodically, you need plants that can live in both wet and dry conditions. When selecting plants, consider if your site is sunny or shady. You might also want plants that vary in height, color, and blooming period. This way your rain garden is not only stopping stormwater runoff but is also providing a beautiful landscape to enjoy all summer long.
