The nature 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 giant tributary Igelsbach, is kept largely constant by a pre-dam. On the Eckersmühlen lock it is channeled from the upper water into the instantly neighboring Rothsee, a reservoir created in the Kleine Roth valley. The Danube-Foremost 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 five dams attributable to their pre-dams, three hydroelectric power 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, a few of which have been expanded to accommodate higher water stream. This water then flows through a energy plant with three megawatts of electrical output at the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted a large number of Max Planck younger analysis groups and Alexander von Humboldt scholarship holders and, with the School of Engineering, has been concerned in the 2 Excellence Initiative institutions that had been 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 at the 5 locks on the southern ramp of the canal, from where it flows downwards over one other barrage into the Rothsee, the place the water is saved and, if vital, in two other ways can also be delivered to the Regnitz. This is done via a energy 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 facility plant. In addition, 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 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-Primary 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 non permanent drought. There are additionally parts and services of the principle-Danube Canal that simultaneously serve other purposes: the canal itself between the connection to the Danube and the outlet into the Schwarzach, together with the inlet and outlet constructions, as well as the pumping stations on the south ramp.

Whereas within the title Foremost-Danube Canal the rivers in the word correspond to the geographical association on the north-facing map, the time period Danube-Essential transition reflects the circulate path of the water pumped from the Danube and flowing within the direction of the principle. Its longest tributaries also circulation into this decrease part of its course, namely the Schwarzach, formerly additionally the Sulz, which has now been reduce up on account of using its valley and water for the primary-Danube Canal and its predecessor, then the one that, to a sure extent, represents it right now Canal itself and finally the Weiße Laber, all left-hand tributaries, whose great size and catchment area displays the rather more distant location of the left watershed to the Rhenish system on this space. This water will enhance the water quality of Regnitz and Essential, 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 elimination of financial institution filtrate for irrigation of the Center Franconian vegetable growing space, which only turned attainable with the switch, or by way of the use of cooling water, etc. In the long term, a median annual switch by way of your complete system of one hundred fifty million m³ of water is anticipated, 5/6 of that by way of the principle-Danube Canal. When water is low, water can be released from the lake again 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 under 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 median of 27.9 million were offered this fashion each year. M³ of water over the water sheath was transferred, after the end of the set up, an average of 26.5 million m³ have been transferred in 1999-2013 and 28.7 million m³ from the Brombachsee have been given, whereby 11 million m³ of extra inflow from the catchment area of ​​the Brombach turns into. Within the years 1994-2013, a mean of 97 million m³ of water have been transferred to the Rothsee yearly, the pure inflow of the small red is approx. The nature 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 situated within the Franconian Seenland, 1.5 kilometers southwest of Pleinfeld on a forest edge. South financial institution of the great Brombachsee, about three kilometers northeast of Langlau and 2.2 kilometers northwest of Ramsberg close to the Weißenberg. Partly paid parking amenities are positioned 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.
