Mrežnica River
Karlovačka županija
The Mrežnica River is a remarkable natural feature located in Karlovac County, Croatia. Stretching approximately 63-64 kilometers, it is famed for possessing an extraordinary number of waterfalls, totaling 93, many of which cascade over natural tufa barriers formed by limestone deposits and algae. Originating in the Kordun region near Slunj, the river flows northward through towns such as Generalski Stol and Duga Resa before joining the Korana River near Karlovac. The river's valley is predominantly of a canyon type, carved deeply into Jurassic and Cretaceous limestone bedrock, creating a picturesque karst environment. Its clear waters, enriched by dissolved limestone, support the formation of tufa dams that create a sequence of lakes and waterfalls, making it one of the most beautiful karst rivers in Croatia. The Mrežnica also plays a role in hydroelectric power production, with the Gojak Hydroelectric Power Plant harnessing its flow along with the nearby Dobra River. The river's ecosystem is sensitive to human impact, emphasizing the importance of preservation efforts. Its combination of natural beauty, geological significance, and hydrological features make the Mrežnica a unique destination for nature lovers and tourists.

Histoire
The Mrežnica River has long been recognized for its unique karst characteristics and abundant waterfalls.
Its valley was shaped over millennia through deep erosion of limestone formations, creating a canyon landscape.
In 1959, human intervention altered the river's flow with the construction of a dam on the Zagorska Mrežnica, creating the Sabljaci artificial lake and redirecting water to the Dobra River for hydroelectric power.
Despite these changes, the river has retained much of its natural charm and ecological importance, with ongoing discussions about designating it as a nature park to protect its pristine environment.
