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 stage of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second giant tributary Igelsbach, is saved largely constant by a pre-dam. At the Eckersmühlen lock it's channeled from the higher water into the immediately neighboring Rothsee, a reservoir created in the Kleine Roth valley. The Danube-Predominant switch system contains a complete of three lakes, together with the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody 5 dams on account of their pre-dams, three hydroelectric power plants on the dams and the Hilpoltstein lock, the canal routes to the Altmühlsee and from there to Brombachsee in addition to 27 different weirs on watercourses, a few of which have been expanded to accommodate larger water move. This water then flows by means of 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 young analysis groups and Alexander von Humboldt scholarship holders and, with the Faculty of Engineering, has been concerned in the 2 Excellence Initiative institutions that were 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 utilizing pumps on the five locks on the southern ramp of the canal, from where it flows downwards over another barrage into the Rothsee, where the water is saved and, if obligatory, in two different ways is also delivered to the Regnitz. This is done by way of a energy plant with a design output of 630 kilowatts (two via-move turbines with 315 kW each). 9.0 m³/s can bypass the facility plant. As well as, floodwater in the higher Altmühl close to Ornbau is diverted into the transfer system, which is meant to guard 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 less than 10 m³/s of water on the Hüttendorf gauge in dry circumstances. With the Danube-Predominant switch, the water management authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Foremost system in Franconia, which is threatened by temporary drought. There are also elements and services of the main-Danube Canal that simultaneously serve different purposes: the canal itself between the connection to the Danube and the outlet into the Schwarzach, along with the inlet and outlet structures, as properly because the pumping stations on the south ramp.

While in the identify Principal-Danube Canal the rivers inside the phrase correspond to the geographical arrangement on the north-dealing with map, the time period Danube-Main transition reflects the move direction of the water pumped from the Danube and flowing in the path of the primary. Its longest tributaries additionally circulate into this lower part of its course, particularly the Schwarzach, formerly additionally the Sulz, which has now been cut up on account of the use of its valley and water for the main-Danube Canal and its predecessor, then the one that, to a certain extent, represents it at this time Canal itself and at last the Weiße Laber, all left-hand tributaries, whose nice size and catchment area displays the rather more distant location of the left watershed to the Rhenish system in this space. This water will enhance the water quality of Regnitz and Major, 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 removal of bank filtrate for irrigation of the Center Franconian vegetable rising space, which only grew to become possible with the switch, or by way of using cooling water, etc. In the long term, a mean annual transfer via the complete system of a hundred and fifty million m³ of water is expected, 5/6 of that via the principle-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 by means of the 8.7 km lengthy Altmühl overpass, which crosses under the watershed in a tunnel over a distance of 2.7 km the Kleiner Brombachsee and from there into the immediately adjoining Großer Brombachsee.

Between 1995 and 2013, a median of 27.9 million were sold this fashion each year. M³ of water over the water sheath was transferred, after the top of the set up, an average of 26.5 million m³ were transferred in 1999-2013 and 28.7 million m³ from the Brombachsee were given, whereby eleven million m³ of extra inflow from the catchment space 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 pink is approx. The character reserve runs about 2.6 kilometers along the south financial institution 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 bank of the great Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg close to the Weißenberg. Partly paid parking facilities are located 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 world of ​​today's Kleiner Brombachsee.
