Lake Neusiedl (Neusiedler See / Fertő): a shallow steppe lake on the Austria–Hungary border

Physical characteristics

Lake Neusiedl measures roughly 36 km from north to south and between about 6 km and 12 km from east to west. Its surface area is commonly given as approximately 315 km², of which the greater portion lies within Austria and a smaller share within Hungary; specific measurements vary with water level and seasonal changes. The lake is very shallow — maximum depths are under two metres — which gives it a broad, flat appearance and pronounced sensitivity to wind and evaporation. For figures and geographic data, consult surface area and dimensions.

• Location: spans Austria (Austrian side) and Hungary (Hungarian side).
• Surface area: roughly 315 km² with seasonal variation.
• Drainage basin: about 1,120 km² in size, feeding the lake and nearby wetlands (drainage basin details).
• Depth: generally less than 1.8 m at its deepest points.

Ecology and wildlife

The lake is fringed by extensive Phragmites reed beds that create a mosaic of open water, marsh and wet meadow. These wetlands are internationally important as breeding, feeding and resting habitat for waterfowl, waders and numerous migratory species. The reed belts also support a variety of fish, amphibians and invertebrates and help moderate the lake’s nutrient cycles. Because of this ecological value and the transboundary nature of the habitats, protective designations cover large parts of the shoreline and adjacent wetlands.

Human use, culture and economy

Human settlement and economic activity around Lake Neusiedl include small towns and villages, agriculture (notably vineyards and orchards in the surrounding plain), tourism, and recreation. The lake is popular for sailing, windsurfing and birdwatching; shallow waters and large open surfaces make it attractive for wind-based sports. Local cultural life features seasonal festivals, historic villages and a long tradition of viticulture in the lake’s microclimate. The lake’s setting has shaped transport routes and settlement patterns in the region for centuries.

Conservation, management and recognition

Because of its ecological importance and the need for cross-border coordination, adjoining protected areas on both the Austrian and Hungarian sides have been established and managed cooperatively. In 2001 the Austrian national park areas together with the Hungarian Fertő-Hanság protected area were inscribed as a transboundary World Heritage Site, recognizing the cultural landscape and the natural values of the lake and its wetlands. For information on the Austrian protected area see the national park, and for details about the World Heritage listing see the UNESCO inscription.

Notable distinctions and visiting

Lake Neusiedl’s combination of shallow water, broad reedbeds and a continental steppe setting makes it distinctive among European lakes. Water levels and the extent of exposed mudflats fluctuate with weather and seasons, creating dynamic habitats that attract photographers, birdwatchers and naturalists. Visitors interested in field identification, guided tours and recreational activities can find local visitor centres and reserves that offer introductions to the landscape, its wildlife and the long-standing human traditions of the region.
