The nature reserves of the Igelsbachsee reservoir, the peninsula within the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are additionally situated on the Brombachsee. The water level of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second large tributary Igelsbach, is kept largely constant by a pre-dam. On the Eckersmühlen lock it is channeled from the higher water into the instantly neighboring Rothsee, a reservoir created within the Kleine Roth valley. The Danube-Fundamental switch system includes a complete of three lakes, together with the Altmühlsee [More Information and facts] with a ring dam and two dams with Brombach and Rothsee, which embody 5 dams due to their pre-dams, three hydroelectric energy plants on the dams and the Hilpoltstein lock, the canal routes to the Altmühlsee and from there to Brombachsee in addition to 27 other weirs on watercourses, some of which have been expanded to accommodate larger water flow. This water then flows by a power plant with three megawatts of electrical output at the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted a large number of Max Planck young analysis groups and Alexander von Humboldt scholarship holders and, with the Faculty of Engineering, has been involved in the two Excellence Initiative institutions that have been arrange at the College of Erlangen-Nuremberg in 2004.

Since 1994, water has been pumped from the Danube to the top of the canal using pumps at the 5 locks on the southern ramp of the canal, from where it flows downwards over one other barrage into the Rothsee, where the water is stored and, if crucial, in two completely different ways can also be delivered to the Regnitz. This is completed via a energy plant with a design output of 630 kilowatts (two by way of-stream turbines with 315 kW each). 9.0 m³/s can bypass the facility plant. As well as, floodwater in the upper Altmühl near Ornbau is diverted into the transfer system, which is intended to protect the Altmühltal under from flooding. When the Altmühl floods, excess water is channeled into the 5 km long Altmühl feeder close to Ornbau to the Altmühlsee. Without the addition, the Regnitz can carry lower than 10 m³/s of water at the Hüttendorf gauge in dry circumstances. With the Danube-Important transfer, the water administration authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Principal system in Franconia, which is threatened by non permanent drought. There are also elements and facilities of the principle-Danube Canal that simultaneously serve other functions: the canal itself between the connection to the Danube and the outlet into the Schwarzach, together with the inlet and outlet structures, as well as the pumping stations on the south ramp.

While inside the identify Most important-Danube Canal the rivers inside the word correspond to the geographical arrangement on the north-dealing with map, the term Danube-Essential transition reflects the flow route of the water pumped from the Danube and flowing within the direction of the primary. Its longest tributaries also flow into this lower part of its course, namely the Schwarzach, formerly also the Sulz, which has now been lower up because of the usage of its valley and water for the primary-Danube Canal and its predecessor, then the one that, to a certain extent, represents it at the moment Canal itself and at last the Weiße Laber, all left-hand tributaries, whose great length and catchment space displays the rather more distant location of the left watershed to the Rhenish system on this area. This water will improve the water quality of Regnitz and Foremost, which has been affected by intensive industrial and agricultural use. This brought with it vital restrictions on use and ecological dangers, e.g. B. for the removal of bank filtrate for irrigation of the Middle Franconian vegetable growing space, which solely grew to become possible with the transfer, or via the usage of cooling water, and many others. In the long term, an average annual transfer by means of all the system of one hundred fifty million m³ of water is expected, 5/6 of that through the main-Danube Canal. When water is low, water can be launched from the lake again into the Altmühl, however as a rule it is initially transported from the Altmühlsee by the 8.7 km long Altmühl overpass, which crosses underneath the watershed in a tunnel over a distance of 2.7 km the Kleiner Brombachsee and from there into the instantly adjacent Großer Brombachsee.

Between 1995 and 2013, a mean of 27.9 million had been sold this way annually. M³ of water over the water sheath was transferred, after the top of the installation, a mean of 26.5 million m³ were transferred in 1999-2013 and 28.7 million m³ from the Brombachsee had been given, whereby 11 million m³ of extra inflow from the catchment area of ​​the Brombach turns into. Within the years 1994-2013, a median of ninety seven million m³ of water have been transferred to the Rothsee annually, the natural inflow of the small pink is approx. The character reserve runs about 2.6 kilometers alongside the south financial institution of the Großer Brombachsee, from the dam of the small Brombachsee To Ramsberg. The wasteland is positioned within the Franconian Seenland, 1.5 kilometers southwest of Pleinfeld on a forest edge. South bank of the great Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg near the Weißenberg. Partly paid parking amenities are situated at the sports activities boat port in Langlau and in Ramsberg. The pouch mill was situated on the Brombach northeast of the Pfofeld district of Langlau and south of Absberg in the area of ​​today's Kleiner Brombachsee.
