How much of a threat does Eurasian Watermilfoil represent to Lake George?
The map at the right (click on it to enlarge) was created using GIS mapping software. It is an attempt to illustrate the threat that milfoil poses to Lake George. The two bands shaded in light and dark red are bathymetric readings showing depths of 0-5 meters and 5-10 meters, which is approximately the range in which milfoil may grow. The green dots represent documented milfoil sites (over 144 total), and the yellow triangles represent the locations of dense beds of milfoil. What can be done? Several aquatic plant management techniques exist to control the spread of milfoil, and all have strengths and weaknesses. Methods available include biological, chemical and physical controls. Individual incidences of Eurasian Watermilfoil must be evaluated prior to determining the method that would be most effective and economic, environmental and technical constraints must also be considered. Below are some of the most common forms of biological, chemical, mechanical and physical controls. Biolo
