NEW ULM - Ever wonder where the rain goes once it hits the ground? That depends on what it lands on and where the water will shed. If it hits a roof, it might go into a gutter and then down a downspout into a grassed lawn. If it hits a parking lot, it can't soak in so it travels to the lowest point until it reaches an area that it may travel to a retention pond or grass area. If it lands on the soil, it will soak into the ground and travel to the groundwater aquifer. But if it lands on bare ground it might cause erosion, depending on the amount of rain.
