history
The dam was completed in 1699 and put into operation for mining in the Neudorf district. From 1779 the calf's eye pond served as an additional storage facility for the pear tree pond . In 1963 a damaged spot in the dam and a no longer functional harrow of a harrowing system were discovered. Therefore, the dam was largely rebuilt from 1964 to 1967. The bottom outlet was also renewed. In 1967 the dam was put back into operation. Since then, the pond has been used for fishing, flood protection and local recreation. In the summer of 2006, the dam was renovated.
Dam and reservoir
The dam is an earth dam with a core seal and 30,000 m³ structure volume. It is 144 m long, 13.4 m high and 5 to 10 m wide; the dam crest is 398.5 m high. The seal consists of turf in the old part , and clay in the new part at the bottom outlet . The flood relief on the right slope has a pipe passage with a diameter of 1 m.
The reservoir is 4.5 hectares (0.045 km²) in size, 320 m long and 130 m wide. It has 0.17 million m³ of storage space and a total storage space of 0.198 million m³. Its catchment area is 1.88 km². The reservoir target is 396.69 m high and the design flood is 2.4 m³ / s.
