Shoreline Design #1: Breakwater with Naturally Colonized Littoral Habitat

Working in harmony with natural physical and biological shoreline processes, this design has been widely implemented with resounding success and is now considered, by many, to be the preferred design for its cost effectiveness and environmental benefits. Lake Rip Rap highly recommends this design for remote shorelines with severe erosion, heavy wave energy and where the littoral slope is less than 12%.

After these breakwaters were built at Kinkaid Lake, the transitional wetlands were naturally colonized and are now teeming with life, both flora and fauna with 121 volunteer plant species; 50 invertebrate species; 25 reptile & amphibian species; 8 mammal species; 12 bird species; and 9 fish species identified *. This large, multi-year project, over 34,000 lineal feet, was built by Macoupin Boats with no heavy equipment on the bank, and is the largest project of its type ever undertaken by transportable riprap boats.

An interesting fact: At Kinkaid Lake, the Macoupin Boats traveled a distance greater than a cruise from Seattle to Tokyo. (over 5,000 miles)
