2003 GPS Survey Page
In 2003 a survey was conducted by Michael Tiedemann that was to document comprehensively the scope of the milfoil problem in Eagle Lake. This survey was conducted using a boat and surface observation using a hand held GPS receiver tracing around the outline of the milfoil patches while taking position measurements. This survey was able to determine that there were approximately 8 acres of milfoil in the lake (2% of the lake surface area) located in 49 separate locations. Of these 49 locations over 60% of the milfoil is located in 6 locations. Further observation by experienced divers determined that milfoil exists below the observable depth from the surface.
