The nature reserves of the Igelsbachsee reservoir, the peninsula in the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are also 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’s channeled from the upper water into the immediately neighboring Rothsee, a reservoir created in the Kleine Roth valley. The Danube-Main switch system includes a total of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody five dams on account 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 higher water circulate. This water then flows through a power plant with 3 megawatts of electrical output on the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted a lot of Max Planck younger research 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 set up on the University of Erlangen-Nuremberg in 2004.

Since 1994, water has been pumped from the Danube to the top of the canal using pumps at the five locks on the southern ramp of the canal, from the place it flows downwards over one other barrage into the Rothsee, where the water is stored and, if necessary, in two different ways is also delivered to the Regnitz. This is done by way of a power plant with a design output of 630 kilowatts (two by way of-movement turbines with 315 kW every). 9.Zero m³/s can bypass the power plant. As well as, floodwater in the higher Altmühl close to Ornbau is diverted into the transfer system, which is meant 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. With out the addition, the Regnitz can carry less 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 Predominant system in Franconia, which is threatened by temporary drought. There are also elements and services of the main-Danube Canal that simultaneously serve other functions: the canal itself between the connection to the Danube and the outlet into the Schwarzach, along with the inlet and outlet buildings, as properly because the pumping stations on the south ramp.

While within the title Major-Danube Canal the rivers within the word correspond to the geographical association on the north-facing map, the term Danube-Important transition reflects the circulate route of the water pumped from the Danube and flowing towards the primary. Its longest tributaries additionally circulate into this decrease part of its course, specifically the Schwarzach, formerly also the Sulz, which has now been minimize up due to the usage of its valley and water for the primary-Danube Canal and its predecessor, then the one which, to a certain extent, represents it right this moment Canal itself and eventually the Weiße Laber, all left-hand tributaries, whose nice size and catchment area displays the far more distant location of the left watershed to the Rhenish system in this space. This water will improve the water high quality of Regnitz and Primary, which has been affected by intensive industrial and agricultural use. This introduced with it significant restrictions on use and ecological dangers, e.g. B. for the removing of bank filtrate for irrigation of the Middle Franconian vegetable rising space, which solely became attainable with the switch, or via the use of cooling water, etc. In the long term, an average annual transfer by means of your complete system of 150 million m³ of water is anticipated, 5/6 of that by way of the primary-Danube Canal. When water is low, water can be released from the lake back into the Altmühl, but as a rule it is initially transported from the Altmühlsee via 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, a mean of 27.9 million had been sold this manner each year. M³ of water over the water sheath was transferred, after the end of the installation, a mean of 26.5 million m³ had been transferred in 1999-2013 and 28.7 million m³ from the Brombachsee were given, whereby eleven million m³ of further inflow from the catchment area of ​​the Brombach becomes. Within the years 1994-2013, a median of 97 million m³ of water have been transferred to the Rothsee yearly, the natural 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 located within 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 close to the Weißenberg. Partly paid parking amenities are located on 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 area of ​​today's Kleiner Brombachsee.
