Behind the northern frontier of the nature reserve of the Pálava  Hills, a cascade of three water reservoirs is located, which was built up on the lower reaches of the river Dyje (Thaya) on the area of 3,226 hectares in the period between 1975 to 1989 . The reason why they were built up consists in the effort to prevent possible floods; but they, however, are also used to breed fish, recreation, and water sports. The negative aspect of the existence of the reservoirs was the loss of an irreplaceable mead forest and the change of the whole of the landscape character.  In the surroundings of the reservoirs there are ideal conditions for vine and fruit growing, which is also a significant characteristic feature of this region. Originally there was a  wonderful natural mead locality in the place of the reservoirs. When three artificial reservoirs were filled up with water in the place of that locality at the end of the 80s, the prevailing feeling of decline was ruling among the conservationists. But the nature came back here just up to a point, and the middle reservoir of Věstonice has been declared  nature reserve after a few years.  This region has become one of the most significant fishing localities of all the South of Moravia.  The complex of the reservoirs represents, as a result of its area and location, the most important winter habitat for some northern species of geese; sometimes it is possible to observe as many as 30 thousand of them. Worth seeing are also sea eagles which also stay here in winter. Wild geese, wild ducks, crested fowls, red-headed ducks, and other sorts of ducks make their nests on the small isles every year. There are colonies of many thousands of gulls, among them also terns, storm gulls, and black-headed gulls can be recognized. In summer it is possible to catch sight of many sorts of swamp birds, smart white and red herons. In winter it is possible to watch northern ducks, big and small divers,  goldeneyes, northern field geese  and  white-faced geese, and the sea eagles  have their regular winter habitat here.
This generic richness of  birdlife is, however, only a substitution of the original unique mead forests which can be seen only on the confluence of the rivers  Jihlava  and  Svratka nowadays.
A natural relic of the Lower Mead of Mušov is located here, protecting the residuum of a firm mead forest and the cover of a scilla, which is in bloom early in spring.
The Upper (Mušov) Reservoir (Nové Mlýny I.) was filled with water in 1979 (531 hectares, dam length  2,484 m, maximum depth 4 m). It bears the name of the extinct village of  Mušov, which was located, however, in the place of the Middle Reservoir. On the northern side of the Mušov Reservoir a holiday resort at  Pasohlávky was built up. There is the hill of Hradisko rising over it, where remnants of a Roman station  dating back to the 2nd century A: D. were discovered.
In the area of the Middle (Věstonice) Reservoir (Nové Mlýny II.) a nature reserve called Věstonice Reservoir was declared in 1994. A road connecting  Dolní Věstonice with Strachotín leads on the dam. The reservoir has the area of 1,033 hectares and its maximum depth is  5.3 m. On one of the isles, which arose after the reservoir filling there are ruins of St. Linhart church which used to be part of the now flooded village of  Mušov. The church is the only remnant of the ancient village of  Mušov, nevertheless, it is a relic of a significant cultural and historical value. St. Linhart´ s church is originally a Romanesque building dating back to the turn of the 12th and  13th century, in the 14th century it was re-built in the Gothic style, so that only the southern wall of  the nave  with a Romanesque portal and windows has been preserved.
Nowadays, at the research in the deconsecrated church in the then contemporary Baroque style, Gothic wall paintings and a painting from the 1st half of the 16th century were revealed. The church, which is probably the oldest Romanesque ecclesiastical building in the district of Břeclav, was transferred to the property of the village of Ivaň in 1999 free of charge.  St. Linhart was an eremite living approximately in the 6th century, who was famous for many miracles and who was the patron saint of prisoners. With its historical and architectural value, with its Romanesque core and Gothic renovation, the memorial has been among the oldest and very rare cultural memorials in the South of Moravia up to now.
The other isle is an archaeological locality, where more than 2,000 graves from the period of the Great Moravian Empire have been discovered. 
The largest of the three reservoirs of Nové Mlýny is the Lower (Nové Mlýny) Reservoir  (Nové Mlýny III.) with the area of 1,668 hectares and maximum depth of 7.8 m.
