The nature reserves of the Igelsbachsee reservoir, the peninsula in the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are also located on the Brombachsee. The water stage 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 in the Kleine Roth valley. The Danube-Important switch system contains a total of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody five dams because of 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 in addition to 27 other weirs on watercourses, some of which have been expanded to accommodate higher water circulate. This water then flows by means of a energy 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 School of Engineering, has been concerned in the two Excellence Initiative establishments that were arrange 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 where it flows downwards over another barrage into the Rothsee, the place the water is stored and, if needed, in two various ways can be delivered to the Regnitz. This is done by way of a energy plant with a design output of 630 kilowatts (two by means of-flow 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 intended to guard the Altmühltal below from flooding. When the Altmühl floods, excess water is channeled into the 5 km long Altmühl feeder near Ornbau to the Altmühlsee. Without the addition, the Regnitz can carry lower than 10 m³/s of water at the Hüttendorf gauge in dry conditions. With the Danube-Main 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 short-term drought. There are also components and facilities 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 nicely because the pumping stations on the south ramp.

Whereas inside the title Most important-Danube Canal the rivers within the phrase correspond to the geographical association on the north-dealing with map, the term Danube-Important transition displays the stream path of the water pumped from the Danube and flowing in course of the principle. Its longest tributaries also flow into this decrease part of its course, namely the Schwarzach, previously additionally the Sulz, which has now been lower up resulting from 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 at present Canal itself and eventually the Weiße Laber, all left-hand tributaries, whose nice size and catchment space reflects the way more distant location of the left watershed to the Rhenish system in this area. This water will enhance the water high quality of Regnitz and Predominant, which has been affected by intensive industrial and agricultural use. This introduced with it vital restrictions on use and ecological dangers, e.g. B. for the elimination of bank filtrate for irrigation of the Middle Franconian vegetable growing area, which only became possible with the transfer, or through the usage of cooling water, and so forth. In the long term, an average annual switch via all the system of one hundred fifty million m³ of water is anticipated, 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 way of the 8.7 km lengthy 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 immediately adjacent Großer Brombachsee.

Between 1995 and 2013, a median of 27.9 million have been offered this way every 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 had been given, whereby 11 million m³ of extra inflow from the catchment area of ​​the Brombach turns into. In the years 1994-2013, a mean of 97 million m³ of water had been transferred to the Rothsee annually, the natural inflow of the small red 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 services are located at the sports boat port in Langlau and in Ramsberg. The pouch mill was located on the Brombach northeast of the Pfofeld district of Langlau and south of Absberg in the world of ​​today's Kleiner Brombachsee.
