The nature reserves of the Igelsbachsee reservoir, the peninsula within the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are also positioned on the Brombachsee. The water degree of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second massive 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-Predominant switch system consists of a total of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody five dams due to 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 other weirs on watercourses, a few of which have been expanded to accommodate higher water movement. This water then flows via a power plant with three megawatts of electrical output on the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted numerous Max Planck younger research teams 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 at the College of Erlangen-Nuremberg in 2004.

Since 1994, water has been pumped from the Danube to the top of the canal utilizing pumps at the 5 locks on the southern ramp of the canal, from where it flows downwards over one other barrage into the Rothsee, where the water is stored and, if essential, in two alternative ways is also delivered to the Regnitz. This is completed via a power plant with a design output of 630 kilowatts (two through-circulation turbines with 315 kW every). 9.Zero m³/s can bypass the power plant. In addition, floodwater in the higher Altmühl near Ornbau is diverted into the switch system, which is meant to protect the Altmühltal under 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 at the Hüttendorf gauge in dry circumstances. With the Danube-Major transfer, the water management authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Important system in Franconia, which is threatened by non permanent drought. There are also parts and facilities of the main-Danube Canal that concurrently serve different purposes: the canal itself between the connection to the Danube and the outlet into the Schwarzach, together with the inlet and outlet buildings, as effectively as the pumping stations on the south ramp.

Whereas in the identify Foremost-Danube Canal the rivers inside the word correspond to the geographical association on the north-facing map, the time period Danube-Principal transition reflects the circulation course of the water pumped from the Danube and flowing towards the principle. Its longest tributaries also circulate into this decrease part of its course, namely the Schwarzach, formerly additionally the Sulz, which has now been reduce up because of using its valley and water for the main-Danube Canal and its predecessor, then the one that, to a certain extent, represents it right now Canal itself and eventually the Weiße Laber, all left-hand tributaries, whose great size and catchment area reflects 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 Main, 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 Center Franconian vegetable growing space, which only became doable with the switch, or by way of the usage of cooling water, etc. In the long term, a median annual transfer by the complete system of one hundred fifty million m³ of water is predicted, 5/6 of that through the main-Danube Canal. When water is low, water can also be launched from the lake again into the Altmühl, but as a rule it is initially transported from the Altmühlsee through 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 instantly adjoining Großer Brombachsee.

Between 1995 and 2013, an average of 27.9 million had been offered this manner each year. M³ of water over the water sheath was transferred, after the end of the installation, a median of 26.5 million m³ were transferred in 1999-2013 and 28.7 million m³ from the Brombachsee were given, whereby 11 million m³ of additional inflow from the catchment space of ​​the Brombach becomes. Within the years 1994-2013, a mean of ninety seven million m³ of water had been transferred to the Rothsee yearly, the natural 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 positioned 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 near the Weißenberg. Partly paid parking services are situated on the sports activities 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.
