Freshwater is an invaluable and essential resource for all forms of life. It plays a vital role in maintaining ecosystems, supporting biodiversity, and regulating the global climate. Safeguarding our freshwater resources is imperative for ensuring sustainable development and the well-being of future generations. Lake Ohrid is the largest drinking water reservoir in Europe. The lake’s waters are renowned for their clarity and purity. Lake Ohrid, along with the City of Ohrid, was designated as a UNESCO World Heritage Site in 1979 and 1980, respectively. This recognition underscores their profound cultural, historical, and environmental significance. The unique natural beauty of the lake, combined with the rich historical heritage of the city, makes both sites invaluable treasures worthy of preservation and appreciation.
