This dive site explores the submerged remains of Borákův mlýn, a historical mill now lying beneath the waters of Slapy Reservoir. Divers can navigate a fascinating underwater landscape featuring a preserved wooden mill wheel, remnants of walls, and the outline of the original riverbed. Navigation is notoriously difficult due to potential low visibility and the complex layout, making a compass an absolute necessity for safe exploration.
The reservoir teems with various freshwater aquatic life. Divers frequently encounter groups of small basses, along with larger predators such as pikes, zanders, carps, catfish, and eels. Crayfish are also a common sight, adding to the biodiversity of this unique underwater environment.
The best time to visit Přehrada Slapy - Borákův mlýn would be during the warmer months (June-August) when water temperatures reach their peak, offering a more comfortable diving experience, although a dry suit is recommended for year-round diving due to the cold conditions at depth (down to 4C). Given the depth, cold water, and navigational challenges, this site is best suited for experienced divers. Freedivers with advanced skills could explore the shallower parts, but the main attractions are deeper.
