Where does rainwater go after it hits the ground?
Much of the rainwater percolates into the ground when it falls to earth. Sometimes the volume of rainwater exceeds the available soil storage capacity or the rain falls at a faster rate than it can percolate into the ground. This excess rainwater or stormwater runoff generally drains into a series of storm drains, depressions, swales, ditches, ponds, lakes, and canals. In Indian River County many of these waterways lead into three very large Relief Canals that discharge directly into the Indian River Lagoon.
