A visually appealing hydroelectric power plant. It's especially beautiful to admire the natural beauty along the river that flows into the lake. There's a nice little restaurant at the top.

After around four years of construction, the new hydroelectric power station in Hagneck was officially opened in 2015. With its energy production of 110 gigawatt hours, it makes an important contribution to supplying the Zealand region with domestic renewable energy. The Hagneck hydroelectric power station is located in a protected floodplain landscape of national importance. Accordingly, the environmental compatibility of this facility was given priority during the comprehensive renovation. With the new, modern power plant, production was increased by 40 percent without any harm to the environment. A lot of emphasis is placed on renaturation around the power plant. The bypass channel for fish is unique in Switzerland and the newly created floodplain forest is a nature reserve of national importance. This achieves maximum energy efficiency under contemporary, ecological conditions. The Jura water correction is a unique and incomparable pioneering work for the development and reclamation of land. Between 1867 and 1891, a sophisticated canal system was used to lower the water levels of the three lakes of Murten, Neuchâtel and Biel. In the future, the land was protected from flooding, and the de-swamped soil now served the population as fertile agricultural land. This unique structure was completed in the second stage between 1962 and 1973. The heart of the Jura water correction was the eight-kilometer-long canal from Aarberg to Hagneck. In contrast to the Nidau–Büren Canal, which was an actual river correction, the Hagneck Canal created a completely new, artificial river. The construction of the Hagneck Canal was breeding ground for further visionary ideas. The first construction work began in 1897 and the facility was put into operation in the summer of 1899. The construction costs amounted to around 3.6 million francs. Hagneck is one of the oldest hydroelectric power plants in Switzerland - a monument of technology and cultural history. Water to electricity – a masterpiece par excellence. Source https://www.bielerseekrafte.ch/de/hagneck/
