The Ohra is a 20 kilometer long river in Thuringia . The source area with the core water and the Silbergraben lies west of Oberhof on the edge of a raised bog.
At the foot of the Böhler both source streams unite and are called Ohra from there . The river name Ohra is first handed down in 1378 in the spelling ora . In 1512 it is called Ohra, 1580 Uhra, 1642 Uhr. In Stutzhaus , the Ohra was also called Wilder Graben .
The river was already of enormous importance in the Middle Ages . It was stately fishing water, was used to drive mills , stamp mills , and copper and iron hammers. Ohrdruf it used the tanner in leather production. From 1639 the wood rafting business was founded on the Ohra and Apfelstädt. The wood was shipped to Erfurt .
A stone bridge fell into the river on December 15, 1856.
The relatively soft , because lime-poor water of the Ohra was ideally suited for the operation of steam engines and locomotives, which is why the Reichsbahn inquired about the construction of a dam . The Ohra Dam , south of Luisenthal , was not built until 1957.
