The first plans already existed in 1781 by the architect Wilhelm Bayer. The lake, upon its construction in 1895–1897, was used only as a utility water reservoir, and until recently as a drinking water reservoir for the Wiental water pipeline of the Wiental waterworks. The content of the basin, which is created by a 240-meter-long and 13-meter-high dam, was 1,430,000 cubic meters at the time.

Wilhelm Kress (1836–1913) himself was an Austrian aviation pioneer and designer born in St. Petersburg. The trained piano maker constructed the Kress hang glider in 1901 - a seaplane that unfortunately never took off from the ground. 2 years before the Wright brothers. The reason for this was the engine built in Stuttgart. Kress expected a take-off weight of 600 kg with an engine output of at least 35 hp. The engine delivered weighed an impressive 380 kg instead of 200 kg and produced only 30 hp instead of 35 hp. Due to the excessive weight of 850 kg, the aircraft was further reinforced. The Wienerwaldsee was subsequently too small. The aircraft recovered after the crash can now be admired in the Vienna Arsenal. After his death, Wilhelm Kress was given an honorary grave at the Vienna Central Cemetery (Group 0, Row 1, Number 65) designed by sculptor Andreas Kögler (1878–1956). The monument, created by sculptor Rudolf von Weigl, was unveiled on October 5, 1913 – about half a year after Wilhelm Kress’ death. Unfortunately, the monument was destroyed at the end of the Second World War, but was restored in 1954. As part of the 100th anniversary of the municipality of Tullnerbach and its elevation to market town status, the monument was re-erected at its current location in 1973.

Wienerwaldsee dam, in Lower Austria, 289 m (dam), 1.4 km long and 0.8 km wide; Vienna reservoir on the Westautobahn, between Pressbaum and Untertullnerbach; Another tributary is the Wolfsgrabenbach. To the northeast of the lake is the Wientalwasserwerk, which feeds the Wientalwasserleitung. The Wienerwaldsee dam is an interesting structure that creates an artificial lake in the Vienna Woods. The lake serves as flood protection for the Vienna River, which flows into the Mulde here. The lake is also a water conservation area that provides a habitat for many rare animals. It's good that swimming and ice skating are prohibited in the lake, but that's logical in a water protection area. But you can go around it by bike or on foot and enjoy the beautiful landscape (sunset!). On the northern bank there is a monument to Wilhelm Kress, a pioneer of aircraft technology who crashed his seaplane here in 1901.

Wilhelm Kress was an Austrian aviation pioneer and designer who was born in Saint Petersburg in 1836 and died in Vienna in 1913. He developed the first modern hang glider model in 1877 and built a motorized aircraft on Lake Vienna in 1901, but it capsized during test runs and never took off. He also invented the control stick for combined control of aircraft in 1900. He is considered one of the pioneers of aviation and influenced other aviation pioneers such as Hiram Stevens Maxim and Otto Lilienthal.
