"First-Class Diving" is born

Mermet Springs was founded by Glen Faith who discovered this abandoned quarry lake early in his days as a recreational diver. Seeing the potential of the property, he made his move by signing a long term lease with the owner and removing tons of scrap and junk from the quarry. Early on, Glen designed the drainage around the 8.5-acre lake to slope away from the water. By doing this the lake remains clean and clear with only rain and spring water feeding the lake.


Over the years, Glen has continued to update the site with campgrounds facilities, training pavilions, and numerous underwater attractions. All revenue generated by Mermet Springs is immediately reinvested into the facility. By doing this, Glen has created a scuba diving facility that offers divers an extraordinary opportunity not found anywhere in the Midwest. With crystal-clear water, 100-foot deep underwater cliffs, sunken wrecks and schools of colored, pre-historic looking fish, Mermet Springs is not just another lake in Southern is a "First-Class Diving" site.

Glen Faith - Owner of Mermet Springs
"One of the must dives in the Midwest"

Mermet Springs is located on US 45 between Vienna and Metropolis, IL. As you enter the site, you'll be amazed at the picturesque wooded backdrop and sheer cliff rising across from the cool-blue water. From the main diving dock, you'll see schools of large bluegill, giant albino channel catfish and, further down, spoonbills! These prehistoric throw-backs have huge mouths and are known to grow larger than five-foot in length. Seeing these "paddle fish" up close will raise your pulse a bit, but don't worry...they are filter feeders and eat microscopic critters that feed on the algae. All these fish are very friendly, almost tame. Fishing is strictly prohibited at Mermet Springs. But feeding the fish is welcome, just watch your fingers with those big cats.
