WATER MANAGEMENT
Vysočina is the source area of important Czech and Moravian rivers. From the perspective of the flow rate, the most important streams or rivers are Jihlava (11.4 m3/sec), Sázava (9.9 m3/sec), Želivka (7.2 m3/sec), and Svratka (7.2 m3/sec). Vysočina is the location of the main European water divide between Doubrava, Sázava, and Želivka, on the one hand, and Svratka, Oslava, Jihlava, Rokytna, and Moravská Dyje (Moravian Thaya), on the other.
Large water dams were built on a number of the Region‘s water streams, several of which are important sources of drinking water, not merely on a regional but also on a national scale. The Pelhřimov and Havlíčkův Brod districts supply drinking water from the Švihov (Želivka) water reservoir to metropolitan Prague; the Žďár nad Sázavou district supplies drinking water from the Vír reservoir to Brno. The most important water reservoirs in the Vysočina Region are: Hubenov, Mostiště, Nová Říše, Švihov, and Vír. On the Jihlava River is a large water dam, Dalešice, consisting of reservoirs Kramolín and Mohelno, whereby the Kramolín reservoir has the highest dike in the country (100 m).
