If you own or manage a lake or pond, your goals may include improving aesthetics, enhancing water quality and strengthening the health of your aquatic ecosystem. While many of the strategies used to achieve these goals are implemented in the spring and summer, it’s never the wrong time to get started. In fact, one beneficial and often overlooked tool is lake mapping—and now is a great time of year to utilize it!
What is lake mapping?
Lake mapping, or bathymetry, involves the measurements of water depth, volume and amount of collected sediment on the bottom of a waterbody. These parameters can reveal quite a lot about what’s happening between the bottom of a lake or pond and the surface, and help waterbody managers and owners make important short- and long-term decisions about the future of a waterbody. The equipment required to perform a bathymetric study includes a hydro-acoustic transducer, GPS receiver and a software platform to union the water depth and location data.
