This dive site, Ilsesee, is a groundwater-fed former quarry pond located south of Augsburg, Germany. Despite its industrial origin, it has been transformed into a thriving aquatic environment through strict ecological concepts and designated protection zones. Divers can explore a unique freshwater ecosystem that defies typical quarry pond expectations, characterized by lush underwater flora and varied topography. Navigation is generally straightforward in such a shallow, contained body of water, likely following natural contours or designated dive paths.
The Ilsesee boasts an impressive array of freshwater flora and fauna. Divers can encounter large sturgeons, pikes, eels, and various perch species, including river perch. The lake is also home to smaller invertebrates such as pond and triangular clams, as well as fascinating freshwater sponges (which should not be touched). The extensive plant life contributes to a vibrant and visually appealing underwater landscape.
The best time to visit Ilsesee would likely be during the warmer months, typically late spring through early autumn, when water temperatures are more comfortable and aquatic life is most active. Divers should respect the protection zones and avoid touching delicate freshwater sponges. Its shallow depths and rich ecosystem make it an excellent spot for both beginner scuba divers and freedivers seeking an accessible and rewarding freshwater experience.
