The character reserves of the Igelsbachsee reservoir, the peninsula within the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are additionally positioned on the Brombachsee. The water degree of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second large tributary Igelsbach, is stored largely fixed 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-Principal transfer system includes a total of three lakes, together with the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which include five 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 as well as 27 different weirs on watercourses, some of which have been expanded to accommodate increased water flow. This water then flows via 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 large number of Max Planck young analysis teams and Alexander von Humboldt scholarship holders and, with the Faculty of Engineering, has been concerned in the two Excellence Initiative establishments that had been arrange on 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 five locks on the southern ramp of the canal, from where it flows downwards over another barrage into the Rothsee, the place the water is saved and, if needed, in two various ways can also be delivered to the Regnitz. This is completed by way of a power plant with a design output of 630 kilowatts (two via-movement turbines with 315 kW each). 9.0 m³/s can bypass the power plant. As well as, floodwater in the upper Altmühl close to Ornbau is diverted into the switch system, which is meant to guard the Altmühltal below 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-Main transfer, 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 momentary drought. There are additionally elements and amenities of the primary-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 structures, as nicely because the pumping stations on the south ramp.

Whereas in the title Principal-Danube Canal the rivers in the word correspond to the geographical arrangement on the north-going through map, the term Danube-Most important transition displays the flow route of the water pumped from the Danube and flowing towards the main. Its longest tributaries also circulation into this lower section of its course, particularly the Schwarzach, formerly additionally the Sulz, which has now been minimize up attributable to 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 right this moment Canal itself and finally the Weiße Laber, all left-hand tributaries, whose nice length and catchment area displays the rather more distant location of the left watershed to the Rhenish system on this area. 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 Middle Franconian vegetable growing area, which solely turned possible with the transfer, or by the usage of cooling water, and so on. In the lengthy run, a mean annual transfer by way of the entire system of a hundred and fifty million m³ of water is expected, 5/6 of that through the principle-Danube Canal. When water is low, water will even be released from the lake again into the Altmühl, but as a rule it is initially transported from the Altmühlsee via the 8.7 km long 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 offered this manner annually. M³ of water over the water sheath was transferred, after the top of the installation, a median of 26.5 million m³ were transferred in 1999-2013 and 28.7 million m³ from the Brombachsee have been given, whereby eleven million m³ of additional inflow from the catchment area of ​​the Brombach becomes. In the years 1994-2013, a median of 97 million m³ of water had been transferred to the Rothsee annually, the pure inflow of the small pink is approx. The nature 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 bank of the nice Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg close to the Weißenberg. Partly paid parking services are positioned at the sports boat port in Langlau and in Ramsberg. The pouch mill was positioned on the Brombach northeast of the Pfofeld district of Langlau and south of Absberg in the world of ​​today's Kleiner Brombachsee.
