You may agree that the fresh and clear water sourced from the mountain spring is the best drinking water for sure. Such water is ‘alive’ because it is unprocessed and unpolluted from any artificial treatment. There are three spring water supply reservoirs in the Gorski Kotar mountain region: the Kupa reservoir, the Crni Lug reservoir and the Lokve lake reservoir. The river Kupa is the most important waterway of this area. Gorski Kotar region has an annual precipitation of around 3,500mm and thus a great hydropower potential. As you walk through Crni Lug you can find a signposted path to Plesevka hill (764m) which contains the spring water reservoir of 250m3, supplying the water for Crni Lug, Bijela Vodica, and Malo Selo villages. It was last rebuilt in 1980 tees. From Pleševka hill you can enjoy a panoramic view of the village and the surrounding mountains, including the Risnjak peak.
