The Dechsendorfer Weiher (Großer Bischofsweiher) and the almost equally large Kleiner Bischofsweiher were created in the Middle Ages by the Bamberg bishops as carp ponds. Due to the large water surfaces and the immediate surroundings, both ponds are of great importance for species and biotope protection, especially for water birds. The Dechsendorfer Weiher are a popular destination for those seeking local recreation due to their proximity and closeness to nature. The pond is used as a bathing pond; however, use was restricted by the algae problem. The bathing ban is also announced locally and by clearly visible signs or signs at the bathing area. The fields to the west of the ponds are in the Sandachse Franken nature conservation project and the forest areas of the Markwald directly adjacent to the east are protected forest. The entire area is a landscape conservation area. The Dechsendorfer Weiher was previously flowed through by the Röttenbach. This has now been created as a new Röttenbach over a length of 1.6 km from the intermediate dam inlet area to the downstream area of the Dechsendorfer Weiher. A near-natural watercourse is intended to improve the previously moderate water structure and create new habitats for the ecological diversity of nature. The lack of passability of the Röttenbach was restored. In the new Röttenbach, nutrients, sediments and also fish from the catchment area of the Dechsendorfer Weiher can be diverted around it into the downstream area of the pond. The pond is no longer in the main tributary but in the bypass and can therefore be managed in terms of the quality and quantity of the incoming water. With the targeted planting of aquatic plants, the pond was returned to a plant-dominated state. [ Source: https://erlangen.de/aktuelles/gewaesserschutz-dechsendorfer-weiher ]
