Infiltration in the Rain Garden
One of the real benefits of a rain garden is water infiltration. When rain water enters the soil it does a lot of good locally as well as decreasing the amount of runoff (and therefore flooding). So what kind of infiltration can be expected? April 5th’s evening storm was a good example. We had roughly 0.38 inches of rain in about ten minutes according to the nearby MSD rain gauge. Here are a series of photos with the first one taken during the rain storm with water running into the micro-basin, the second just as it was ending with water being retained and the third ten minutes after it ended with the water fully infiltrated into the ground.
