If you need information on your lake’s aquatic plant community as part of a weed harvesting program, herbicide treatment program, exotic plant monitoring program or simply to assess the ecological health of your lake, Cason & Associates has the tools and expertise help you manage your aquatic plants.




We use the reproducible point-intercept survey method developed by the Wisconsin Department of Natural Resources to map and monitor aquatic plant communities. These surveys provide statistical data to document and assess changes in the plant communities including the number of species present, species abundance, percent frequencies, plant growth depths, floristic quality and much more. The data collected from these surveys can be readily compared to other lakes, and are regularly used to assess long-term management impacts.


To manage aquatic invasive species, a different type of survey is required. Aquatic invasive species surveys cover the entire littoral zone of a lake and rely on visual searches, side and down imaging sonar and rake throws to locate and identify any aquatic invasive species in your lake. 

Once located, the species are identified and mapped using a GPS. We then create in-depth, highly accurate distribution maps using ArcGIS for our clients. These maps and the data collected during the survey are essential to guide targeted management activities


If your goal is to manage white water lilies, spatterdock, pickerelweed, and other emergent plant species, we offer emergent plant surveys. These surveys map the location and size of all emergent plant species and are used to guide plantings, harvesting, and fish and wildlife habitat.
