The character reserves of the Igelsbachsee reservoir, the peninsula in the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are also positioned on the Brombachsee. The water level of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second massive tributary Igelsbach, is stored largely constant by a pre-dam. At the Eckersmühlen lock it is channeled from the upper water into the immediately neighboring Rothsee, a reservoir created within the Kleine Roth valley. The Danube-Main transfer system includes a complete of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which include 5 dams because of 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 as well as 27 other weirs on watercourses, some of which have been expanded to accommodate increased water movement. This water then flows via a power plant with three megawatts of electrical output on the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted a large number of Max Planck young research teams and Alexander von Humboldt scholarship holders and, with the School of Engineering, has been involved in the 2 Excellence Initiative institutions that were set up 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 on 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 obligatory, in two completely different ways can be delivered to the Regnitz. This is done via a power plant with a design output of 630 kilowatts (two by way of-move turbines with 315 kW each). 9.0 m³/s can bypass the ability plant. As well as, floodwater in the higher Altmühl near Ornbau is diverted into the switch system, which is meant to protect the Altmühltal beneath from flooding. When the Altmühl floods, excess water is channeled into the 5 km lengthy Altmühl feeder near Ornbau to the Altmühlsee. With out the addition, the Regnitz can carry lower than 10 m³/s of water on the Hüttendorf gauge in dry circumstances. With the Danube-Principal transfer, the water management authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Important system in Franconia, which is threatened by non permanent drought. There are additionally parts and facilities of the principle-Danube Canal that simultaneously serve other purposes: the canal itself between the connection to the Danube and the outlet into the Schwarzach, together with the inlet and outlet structures, as nicely because the pumping stations on the south ramp.

Whereas inside the name Principal-Danube Canal the rivers in the phrase correspond to the geographical arrangement on the north-going through map, the time period Danube-Essential transition reflects the move direction of the water pumped from the Danube and flowing in course of the main. Its longest tributaries additionally move into this lower section of its course, namely the Schwarzach, previously additionally the Sulz, which has now been lower up on account of the usage of its valley and water for the primary-Danube Canal and its predecessor, then the one which, to a sure extent, represents it today Canal itself and finally 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 space. This water will improve the water high quality of Regnitz and Principal, which has been affected by intensive industrial and agricultural use. This introduced with it important restrictions on use and ecological dangers, e.g. B. for the removing of financial institution filtrate for irrigation of the Center Franconian vegetable growing space, which only grew to become attainable with the transfer, or by way of the use of cooling water, and many others. In the long term, an average annual switch by means of your entire system of one hundred fifty million m³ of water is expected, 5/6 of that via the principle-Danube Canal. When water is low, water may also be launched from the lake back into the Altmühl, but as a rule it is initially transported from the Altmühlsee through the 8.7 km lengthy Altmühl overpass, which crosses below the watershed in a tunnel over a distance of 2.7 km the Kleiner Brombachsee and from there into the instantly adjoining Großer Brombachsee.

Between 1995 and 2013, an average of 27.9 million have been offered this way annually. M³ of water over the water sheath was transferred, after the top of the set up, an average of 26.5 million m³ have been transferred in 1999-2013 and 28.7 million m³ from the Brombachsee have been given, whereby eleven million m³ of extra inflow from the catchment space of ​​the Brombach turns into. Within the years 1994-2013, an average of ninety seven million m³ of water were transferred to the Rothsee annually, the pure inflow of the small red is approx. The character reserve runs about 2.6 kilometers alongside the south bank of the Großer Brombachsee, from the dam of the small Brombachsee To Ramsberg. The wasteland is situated in the Franconian Seenland, 1.5 kilometers southwest of Pleinfeld on a forest edge. South financial institution of the nice Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg near the Weißenberg. Partly paid parking facilities are positioned at the sports 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 realm of ​​today's Kleiner Brombachsee.
