Water geometry from OpenStreetMap + a water-cooling score per 250 m cell · as of: August 2026
“By the water” is a favourite in every listing. wohnwahn measures it instead: 9,034 water features across Vienna, from the Alte Donau to the Donaukanal, and a cooling score per inhabited 250 m cell. Right now Leopoldstadt has the largest share of homes near water (76% of its residential spots).
And we say honestly where the trade-offs are: mosquitoes along the floodplain, party noise on the canal, and a price premium at the Alte Donau.
Deeper blue means closer to open water. Every square is an inhabited 250 m cell; the Danube, the Alte and Neue Donau, the canal and the big lakes count, the channelled Wienfluss and small brooks do not.
Only inhabited cells are coloured. This is a proximity model for the big open waters, NOT an official flood map. Tap the map for the water-proximity score at that exact spot.
Ranked by the share of residential spots near a big open water, so it rewards districts with many waterside homes, not a single luxury shoreline. Linked: the full profile in the atlas.
Method: proximity to the big open waters per inhabited 250 m cell (the Danube, the Alte and Neue Donau, the canal and the big lakes count), bigger and closer water weighs more, share of cells above the threshold, clipped to the real boundary. Channelled races and small brooks are deliberately excluded, they don’t make a waterside home. A district scores high when many homes sit near water, not because of one exclusive shore. Prices: asking prices per m² (condos), immopreise.at / derStandard-Preisspiegel, as of Dezember 2025.
Water usually means the edge of the city. These places prove otherwise: many waterside homes AND within 20 minutes of Stephansplatz by transit (Kaisermühlen on the U1 is the classic).
Our data shows how close and how cooling the water is around an address. Whether you actually see it depends on the floor, the orientation and the building, that’s what the listing and a viewing tell you.
The Alte Donau is a calm bathing lake (quiet, pricier); the Donaukanal is central and lively (bars, summer crowds, more noise). Both are “by the water”, but they live completely differently. Check the noise layer on the search map for the canal side.
Homes right on the Danube floodplain (Lobau, Alte Donau backwaters) are green and cool, but the mosquitoes are real from June to August. We don’t measure them, but they belong in the decision.
Much of the Wienfluss is channelled and partly covered. “By the Wien river” rarely means the open water people imagine, so read the map, not just the street name.

wohnwahn measures water proximity and cooling, not flood risk. Vienna’s flood protection is designed for extreme Danube discharge and the Alte Donau stays flood-free; the 2002 and 2013 floods caused no major damage in the city. But we do not issue a flood-risk rating per address, for that, check the official HORA hazard map.
The Alte Donau is a still bathing lake: quiet, green, more expensive, a summer-holiday feel. The Donaukanal is central and urban: bars, cycle paths, summer crowds and more noise. Both are “by the water” but suit very different lives.
Innere Stadt for example: many waterside homes and still ≈ 5 minutes from Stephansplatz by transit. Kaisermühlen on the U1 is the textbook case: swimming in summer, ten minutes to the centre.
