Zebra musselHydrilla

Variable Milfoil is a non-native plant that has taken over many bodies of water. The plant is spread easily when boat propellers, fishing line, or other recreational gear cuts off pieces of the plant. These pieces then can travel to new parts of the body of water to root or “hitchhike” on boats and trailers, diving gear, and fishing equipment to a new body of water. A single fragment of this plant can cause a new infestation.

Zebra Mussels are about the size of a human fingernail but cause damage to water supplies, industrial processing plants, and marine engines. Zebra mussels clog water intake pipes and can give bad odors to bodies of water. Their sharp shells also can cut the feet of swimmers.
