Kingfisher Lagoon, connected to Kent Lake by a culvert under the road, changed in appearance over the years as soil from the surrounding landscape washed into the water and gradually raised the lake bottom. Aquatic plants also died and settled to the bottom, adding to the filling-in process. As this buildup continued, land plants moved into the former aquatic area and the shoreline advanced toward the center of the lake. Eventually, a lake disappears altogether through a process known as eutrophication or aquatic succession. The shoreline shown for 1956 differed from the shoreline in 2015.
