Shallow freshwater grass-bed quarry dive with beginner-friendly shore entry.
Shallow freshwater grass-bed quarry dive with beginner-friendly shore entry.
Atlantic Quarry - Kelp Forest is the shallow shore-side grass bed at Schildberg Rock Quarry in Atlantic, Iowa. The route follows the shoreline from the entry road toward the north side and stays in a simple freshwater habitat rather than a deep quarry wall. Tall grasses create a forest-like lane for beginner dives, with bass, bluegill, carp and catfish around the edge. It suits calm practice laps, checkouts and easy photo passes.
