Aquatic Invasive Species

Aquatic Invasive Species (AIS) are non-native plants or animals that are introduced into the region, usually by humans.  They can cause extensive environmental damage to the lake by replacing the species that are needed by the native fish and wildlife. The species that have been found in Big Sandy Lake are Flowering Rush,  Purple Loosestrife, and Chinese Mystery Snails.  Big Sandy is rated high risk, but careful boating practices can prevent the spread of AIS.  Click on the images below for larger views.
