There are three crown security overflows in the dam, their width is 12 meters and maximum capacity is 3x 336,6 m3/s. On right bank is lock. Length of lock is 45 meters and width is 6 meters.
Fitting with equipment to the locks began in 2009. The first vessel would be to sail through here in 2013, when it will open the last stage of navigable river from the Orlík dam to České Budějovice.

Component of the dam Hněvkovice is small hydroelectric power station with installed capacity 9.6 MW. Annual generation was 30,5 GWh in 2009 and Annual generation in 2010 was 30,7 Gwh. Two turbines type Kaplan are in the engine room.

Area of water reservoir is 276,7 ha and capacity is 21,095 million m3. The average depth in a water reservoir is 7.9 m. After deepen will navigational depth the riverbed , the depth of riverbed will 1,6 m.
