Purpose of the reservoir
The lake is fed by the Happurger Bach and its left tributary Kainsbach . The Happurg pumped storage power plant of the Franconian Überlandwerk (today E.ON ), which went into operation in 1958, uses the water from the lake and the associated upper basin on the Deckersberg to generate electrical energy. The average size of the lake is about 55 hectares. The lake takes its name from the neighboring village of Happurg . It was built by the Nuremberg architect and culture prize winner of the city of Nuremberg, Franz Reichel .
Due to water ingress in the upper basin of the pumped storage power plant, the power plant function has been out of operation since January 2011. The renovation work has been postponed and completion was initially planned for 2016. In 2013, the restart was postponed to 2017 after the renovation report was available.
In 2015, a new date for the completion of the renovation was again set, which has now been set for 2019. On site in Happurg, it is learned that this deadline will probably not be kept either, as part of the power plant equipment has already been expanded as spare parts for other equipment. In 2018, no prospects were seen for this date and the use of a three-digit million amount for the repair.
The reservoir, which was created in 1955 for the purpose of generating electricity, is located in the low mountain range of the Franconian Alb .
The closest town is Hersbruck (about three kilometers).
The lake can be reached from the A9 Nuremberg-Berlin motorway , Lauf-Hersbruck exit, on federal road 14 towards Hersbruck, past Hersbruck to the Happurg junction. The road in the direction of Alfeld leads directly past the south bank of Lake Happurger See. It is about 14 kilometers from the motorway. Alternatively, you can leave the A6 Nürnberg – Amberg motorway (towards Prague) at the Alfeld exit and take the state road through Alfeld towards Hersbruck to the lake.
The lake can also be reached with a regional bus line from Hersbruck.
The area around the lake is designated as a landscape protection area.
Due to the water sports possibilities, the reservoir is a destination for vacationers and bathers. There is a restaurant with an outdoor area on the western bank. In front of it there is a bathing beach and a children's playground, behind it a parking lot. Surfers , sailors and stand-up paddlers will find admission points here. Internal combustion engine boats are not permitted.
The pumped storage power plant has not been in operation since 2011. The water level is now constant until it is possible to resume. In the past, the reservoir was not always fully flooded after dry periods and then had a lower water level. Due to the pumped storage operation, the water level had changed continuously with fluctuations of up to 4.5 meters, depending on the electricity demand.
Pedal boats were rented out until 2017. To the north is the Hersbruck sailing club and its clubhouse. At the southern end there are places for fishermen and on the eastern bank there is a nudist beach.
A well-developed path leads around the lake with stops on the Happurger Geschichtsweg. Circular trails enable hikes in the area around Hersbrucker Schweiz with nature trails, geological trails and geological trails. A marked network of hiking trails leads through the landscape of the Franconian Alb, u. a. to the high Arzberg with the observation tower (four kilometers to the west).
At the north-eastern end over the lake are the Dogger tunnels , built by prisoners of the Hersbruck satellite camp as forced labor , for an underground factory in which BMW aircraft engines that were important for the war effort were to be produced.
