Lake & Pond Surveys

Prior to aquatic management, information must be collected about a lake: its current state and identification of the problem plants. This information is collected through what is called a Lake Vegetation Assessment. These surveys are often required by state governmental agencies in order to permit unique or whole lake treatments.

Lake Vegetation Assessments use a scientific approach to determine the plant communities of the lake. The following information is collected and prepared:

Vegetation types by depth
Presence and distribution of aquatic invasive species as well as native plants
Frequency of occurrence of aquatic plant community

Our experienced staff evaluates the assessments, and prescribes treatments which are both environmentally safe and effective

Plant Assessments

Studies called bioassays are becoming more readily available for aquatic plants. Plants are taken from the lake and examined to determine how susceptible it will be to the different herbicides. More importantly these bioassays can determine the precise amount of each herbicide required to control the plants. Some plants are more tolerant to the herbicides than others. This allows us to not only be selective by product type, but also by the rate of application. PLM can use the least amount of herbicide to effectively and successfully remove only certain types of vegetation.
