A freshwater fish reef is made up of objects that provide cover, structure and a habitat for spawning. Most lakes and ponds have natural reefs but creating an artificial reef can be done with old Christmas trees, brush or other items that attract freshwater fish.

This process will determine if the artificial reef will be beneficial and not cause harm to the fish, water or environment.
