Lake Managers are directly involved in managing ponds, lakes, reservoirs and other bodies of water including their watersheds. Lake Managers make recommendations to governing groups and implement proper methods that affect the quality and use of these water bodies.


Monitoring water quality is extremely important because it varies throughout the day, day-to-day, week, month and even season.


Mapping helps to provide valuable metrics imperative to targeting plant control resources in problem areas that may not be visible from the surface.


Maintaining adequate dissolved oxygen (DO) levels in water is a critical component to sustaining healthy ecosystems in lakes and ponds.
