Dalešice Reservoir, Pumped-storage reservoir in Třebíč District, Czech Republic
Dalešice Reservoir is a pumped-storage reservoir on the Jihlava River southeast of Třebíč, built from 1970 to 1978 together with the lower Mohelno reservoir. Its water surface lies at 381.5 m and reaches a maximum depth of 85.5 m, the deepest in the Czech Republic. The 100 m rockfill dam with a clay sealing core stands at river kilometre 66 and is open to the public.
The reservoir came into being in the nineteen seventies to supply cooling water to the Dukovany Nuclear Power Station and generate electricity at the same time. The construction changed the course of the Jihlava River and created a new body of water in the Vysočina region.
The reservoir takes its name from Dalešice, the village on its shore. Since 1 July 2007 a recreational boat has run on the water; the 26-metre, 30-tonne Vysočina was followed by the Horácko, which seats 115 passengers and carries bicycles. Anglers fish the stretch registered as the Jihlava 7–8 revír.
Paths along the shore give access to different viewpoints where you can see the water and the surrounding hills. On warm days the shore is busier, while fewer visitors come outside the summer months.
The dam is among the tallest of its kind in Europe and consists of piled rock that forms a massive barrier. From certain points you can see the full height of the structure rising above the valley.
