The road is unfriendly. You'll still have to cross the stream, but then you'll have to imagine where the road goes.

Large water reservoirs used as water supply points in case of fire. We ended up here by accident, because the route was planned straight, but it didn't look too good, so we modified it a bit. It turned out to be a very good idea, because this straight path (looking from the memorial site) is basically only on the map and then it ends.

In the 1950s and 1960s, significant water deficits were noted in the upper Narew river basin. In connection with this, in the regional perspective plan for water management of the former Białystok voivodeship from 1964 (currently part of the Podlaskie voivodeship), studies were undertaken on the location and determination of the capacity of a water reservoir necessary to cover these deficits. During this work, several location variants were considered. Ultimately, the location of the reservoir in the area of the village of Siemianówka was chosen. The first works began in May 1977. The original plans assumed that Zalew Siemianówka (this is the name given to this reservoir, although others are also used: Jezioro Siemianówka, Jezioro Siemianowskie. 289 farms from eight villages were bought and expropriated for the construction of the reservoir, of which: Rudnia, Garbary, Bołtryki, Łuka and Budy were completely liquidated. Two housing estates were built for the needs of the displaced: in Michałów (30 apartments) and Bondary (135 apartments). The village of Nowa Łuka was also established. The damming of water began in 1988 when the old bed of the Narew River was blocked with a frontal dam. In February 1989, 1,300 ha of land was flooded. This level was maintained throughout the summer, and for the winter the water level was lowered by 1 meter. In April 1990, water storage was resumed and the elevation of 143.00 was reached, which allowed for the flooding of 1,700 ha. In 1991, finishing works were carried out, which did not allow for further water accumulation. In 1992, the water was increased by 1 meter, which allowed for the flooding of 2,450 ha, and in the first days of May 1993, the elevation of 144.56 was reached. The area of the reservoir is 3,250 ha (Lake Wigry is smaller by over 1,000 ha). The maximum area of the reservoir reaches 32.5 km2, while the minimum - 11.7 km2. The average depth when completely filled is 2.5 m, the maximum 7.0 m. With a minimum filling, it is 1.5 m and 4.1 m, respectively. The length of the reservoir reaches a maximum of 13.5 km with a width of 1.4 km. https://www.siemianowka.pl/zalew-siemianowka.html

This large lake is located in the Upper Narva Valley in Podlaskie Voivodeship, just north of the Białowieża Forest. It was formed between 1977 and 1990 following the blocking of water by a dam built in the narrowing of the valley.
