Historical Background and Construction

Hostivař Reservoir was developed between 1959 and 1963 to regulate the Botič Stream, protect southeastern Prague from flooding, and provide accessible recreation for a rapidly expanding urban population (prague.fm). The reservoir covers approximately 42 hectares, with a maximum depth of 12 meters and a total volume of about 1.3 million cubic meters. Its creation reflected the socialist ideals of post-war Czechoslovakia, emphasizing collective well-being and access to nature for all residents.

Urban Integration and Development

Initially surrounded by forests and meadows, the reservoir gradually became integrated into the urban fabric of Prague 15. The 1970s and 1980s saw the addition of sandy beaches, a nudist beach, sports courts, and improved infrastructure (prague.fm). Modern developments continue to enhance its accessibility and amenities, including new residential, office, and medical facilities as well as upgraded transport connections (expats.cz).

Hostivař Reservoir is a democratic space open to all, fostering community spirit through public events, sports tournaments, and festivals. It serves as a gathering point for families, students, locals, and tourists, reinforcing its role as a key social and recreational asset in Prague (prague.fm).

Environmental and Ecological Value

Beyond its recreational role, the reservoir is crucial for local flood mitigation and supports the rich biodiversity of Hostivař Forest Park. The reservoir and park together form part of the Hostivař-Záběhlice Nature Park, serving as vital habitats for flora and fauna. Water quality is regularly monitored, and innovative technologies like ultrasonic cleaning are used to combat cyanobacterial blooms, ensuring safety for both visitors and wildlife (hostivarskaprehrada.cz; refoorest.com).

Prague’s broader green strategy, including being named European Forest City for 2025, highlights the reservoir’s role in climate adaptation, air purification, and urban cooling (expats.cz).
