The Słupia, the Radunia, and the Wierzyca are rivers whose location and energy of water flow was taken advantage of to build hydroelectric power plants. Many of them are still operating and can be visited. The oldest such power plant in Europe, Struga, or the Radunia’s highest-situated plant in Bielkowo, are only a few of the facilities well worth seeing. The principles of physics, chemistry, and mathematics are contained in machines and post-industrial sites, and presented at thematic exhibitions, such as in the Hewelianum Centre.

Dam Mylof

The hydrotechnical system of the Brda in the Tuchola Forest is a set of mostly still-active devices, which have regulated the hydrographic conditions of the area for about 150 years,

and for the last several dozen years have been used as a fascinating and popular canoe trail


It all started in mid-19th Century with the Prussian demand for hay to feed their horses. Work started on taking advantage of the Brda as a vehicle to carry out the strategic plan. The plan's main component was the water body in Zapora with the broadened river bed of the Brda, which accumulated and dammed up the water. From here, water flowed in a thirty-kilometre-long channel that split into a number of arms, and on to the so-called Czerskie Łąki. The local dam is one of the oldest structures of its kind in Poland. The Great Brda Channel, with all its attractions and breathtaking views, and also its sluggish current and low depth, is an excellent place for entire families to start their canoeing adventure.
