The Zaya is a tributary of the March in the Lower Austrian region of Weinviertel .
The name is of Germanic origin and is made up of * sauj- ("moist") and * ahwo ("waters") and probably means "the kingdom of water". The water was first mentioned in 1045 as "Zaiove".
It rises south of the village of Klement in the Leiser Mountains and flows through the communities of Ernstbrunn , Gnadendorf , Asparn an der Zaya , Mistelbach an der Zaya , Wilfersdorf , Hauskirchen , Neusiedl an der Zaya , Dobermannsdorf , Ringelsdorf and flows into the March at Drösing . The Zaya flows mainly in a west-east direction, is 58 km long and covers an altitude difference of 230 meters. Between Asparn and Dobermannsdorf, the route of the Korneuburg – Hohenau local railway , which has now been closed for passenger traffic, runs parallel to the river.
The Zaya used to meander in the lowlands of the lower Zaya Valley and was surrounded by extensive wetlands and alluvial forests . Until the early modern era , water power was used extensively by mills. There were once almost 50 of them on the Zaya, one every 1.2 kilometers on average. From the end of the 18th century, the water began to be straightened and lowered. The river has been degraded to a drainage ditch, the task of which is to drain the water as quickly as possible. On the one hand, this should protect the settlements against floods and, above all, enable more intensive agricultural use of the river area. Since wetlands and backwaters serve as receiving waters during floods and dampen the flood peaks in the places downstream, the measures have on the contrary increased the risk of flooding in many places. In addition, valuable habitats for animal and plant species that have now become rare have been destroyed and biodiversity has been reduced. The Zaya meadows in Mistelbach are the most important remnants of the former wetlands of the Zaya.
