The character reserves of the Igelsbachsee reservoir, the peninsula in the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are additionally located on the Brombachsee. The water stage of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second large tributary Igelsbach, is kept largely fixed by a pre-dam. At the Eckersmühlen lock it's channeled from the upper water into the immediately neighboring Rothsee, a reservoir created in the Kleine Roth valley. The Danube-Primary switch system contains a complete of three lakes, together with the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embrace five dams due to their pre-dams, three hydroelectric energy plants at the dams and the Hilpoltstein lock, the canal routes to the Altmühlsee and from there to Brombachsee as well as 27 different weirs on watercourses, some of which have been expanded to accommodate increased water circulate. This water then flows by way of 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 numerous Max Planck younger analysis groups and Alexander von Humboldt scholarship holders and, with the Faculty of Engineering, has been concerned in the two Excellence Initiative establishments that were arrange at the University of Erlangen-Nuremberg in 2004.

Since 1994, water has been pumped from the Danube to the top of the canal using pumps on the five locks on the southern ramp of the canal, from the place it flows downwards over another barrage into the Rothsee, the place the water is saved and, if necessary, in two different ways is also delivered to the Regnitz. This is completed by way of a power plant with a design output of 630 kilowatts (two by means of-stream turbines with 315 kW each). 9.Zero m³/s can bypass the ability plant. In addition, floodwater within the upper Altmühl near Ornbau is diverted into the transfer system, which is meant to protect the Altmühltal below 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 on the Hüttendorf gauge in dry circumstances. With the Danube-Essential transfer, the water administration authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Main system in Franconia, which is threatened by non permanent drought. There are additionally parts and facilities of the main-Danube Canal that simultaneously serve other purposes: the canal itself between the connection to the Danube and the outlet into the Schwarzach, along with the inlet and outlet structures, as effectively because the pumping stations on the south ramp.

Whereas in the name Fundamental-Danube Canal the rivers in the phrase correspond to the geographical association on the north-facing map, the term Danube-Essential transition reflects the circulation course of the water pumped from the Danube and flowing inside the route of the primary. Its longest tributaries also flow into this decrease part of its course, particularly the Schwarzach, formerly also the Sulz, which has now been reduce up because of using its valley and water for the main-Danube Canal and its predecessor, then the one that, to a sure extent, represents it right this moment Canal itself and finally the Weiße Laber, all left-hand tributaries, whose nice length and catchment area reflects the way more distant location of the left watershed to the Rhenish system on this area. This water will enhance the water quality of Regnitz and Primary, which has been affected by intensive industrial and agricultural use. This brought with it significant restrictions on use and ecological dangers, e.g. B. for the removing of financial institution filtrate for irrigation of the Middle Franconian vegetable rising area, which solely became attainable with the transfer, or via the use of cooling water, and so on. In the long run, a mean annual switch by way of the entire system of one hundred fifty million m³ of water is anticipated, 5/6 of that through the primary-Danube Canal. When water is low, water may also be released from the lake again into the Altmühl, but as a rule it is initially transported from the Altmühlsee by means of 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 were offered this way every year. M³ of water over the water sheath was transferred, after the top of the installation, a mean of 26.5 million m³ had been transferred in 1999-2013 and 28.7 million m³ from the Brombachsee have been given, whereby eleven million m³ of further inflow from the catchment space of ​​the Brombach turns into. Within the years 1994-2013, a mean of ninety seven million m³ of water had been transferred to the Rothsee yearly, the natural inflow of the small purple 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 located in the Franconian Seenland, 1.5 kilometers southwest of Pleinfeld on a forest edge. South financial institution of the good Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg near the Weißenberg. Partly paid parking facilities are located on 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.
