Dobrá voda, Spring box in Dalejské údolí, Prague, Czech Republic

Dobrá voda is a spring box located in a protected valley at the edge of Prague, where clean water flows from underground sources. The installation sits within a quiet landscape with marked trails and natural terrain features.

The spring's name comes from an old folk term for the wooded ravine above it. In October 2017 the stone basin was rebuilt through the participatory budget of Prague-Slivenec district, on a proposal from the district; Pavel Jeřábek of Hnutí Brontosaurus carried out the work and Truhlářství Javůrek of Holyně made the wooden parts. A wooden roof, a log bench, a stone table and an access footbridge were added, and the school club of the Slivenec primary school took on its patronage.

The name Dobrá voda comes from an old folk term for the wooded ravine above the spring. Since the October 2017 reconstruction, funded from the Prague-Slivenec participatory budget, the school club of the Slivenec primary and nursery school has held patronage over the spring.

The spring box is accessible via marked trails through Dalejské valley, suitable for easy walks. The best visiting conditions occur during dry weather, when paths are easy to navigate and water flows clearly.

The spring yields only about 0.05–0.1 litres per second, and output may fall further as rainfall decreases. Analyses found elevated enterococci and psychrophilic bacteria from surface seepage, so the water is not reliably potable despite meeting some decree 252/2004 limits.
