Lake Studies/Water Quality Testing/Aquatic Plant ID
Lake Mapping - The interface of LCG Sonar and GPS/GIS technology allows for a 1 second interval depth record following contours and revealing the structure of the lake. Lake mapping takes place prior to major aquatic plant growth. This map will serve for years to come in the aid of monitoring aquatic plant growth areas, sediment deposits not to mention ideal fishing structure. Plant Survey - When aquatic plants appear, the areas of plant growth, type, species and volume is identified. This survey will allow the effective management of desired aquatic vegetation versus undesired. When referenced to the map, these areas can be monitored along with the development of new aquatic plant growth areas in the future. Plant Surveys determine the effectiveness of herbicide applications, proper herbicide selection are critical to cost effective aquatic habitat management. Water Quality Testing - Periodic broad spectrum water quality testing is often overlooked and rarely utilized. Initially the test results may not yield any significant data. However, when proper protocol and a ridged chain of custody is adhered to, a baseline is established that indicates fluctuations within the test parameter data from year to year. These fluctuations can assist in creating source solutions especially within the realm of nutrient load indicators. Fish Survey - A Fish Survey reveals more than population and species ratio's. This data is compiled to address stocking or removal events, feeding programs and parasite controls. Adjustments in the Pelagic Food Web may assist in colonization of phytoplankton/zooplankton and encourage large body Daphnia (algae grazers) populations that may reduce algae volume. A "Creel Study" recorded by the pond owner for 1 year or longer, that include the dates, species, size, sex and destiny of each fish caught or found dead prior to the shock survey provides invaluable data to achieve accurate fish population estimates. Nutrient Budget - In the future a watershed analysis in the form of a Nutrient Budget may be desired. In concert with detailed lake data, nutrient load areas can be identified and sediment deposit samples may aid in dredge considerations. Watershed management principals can then be applied to preserve or improve the water quality of the lake. Without the supporting data of a Lake Study - little measurable information can be derived from watershed management efforts alone. Targeted Plant and Algae Management - Non-native invasive species typically account for areas inundated with weed growth. Certain invasive plants can be targeted successfully and not affect native plants. Other plants may move into areas with less competition after a herbicide treatment. At times, plants in undesired plant growth areas of the lake may prevail to maintain a 20% aquatic plant to 80% open water ratio in order to treat overabundant invasive native and non-native species elsewhere. Elective control of aquatic plants has merit provided an appropriate balance is maintained.

Aquatic Weed and Algae Control
Lake Management revolves around a comprehensive Lake Study. Without the proper information to develop a plan of action - goals and desires are rarely met and budget concerns are often compounded. Consider this option as you deliberate the future management of your lake.
