Just a speck of land

The nature reserves of the Igelsbachsee reservoir, the peninsula within 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 stored largely constant by a pre-dam. On 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-Principal transfer system consists of a total of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody 5 dams as a result 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 as well as 27 other weirs on watercourses, a few of which have been expanded to accommodate higher water move. This water then flows by way 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 numerous Max Planck young research groups and Alexander von Humboldt scholarship holders and, with the Faculty of Engineering, has been involved in the 2 Excellence Initiative establishments that were arrange at the College of Erlangen-Nuremberg in 2004.

Since 1994, water has been pumped from the Danube to the highest of the canal using pumps at the 5 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 necessary, in two different ways is also delivered to the Regnitz. This is completed through a energy plant with a design output of 630 kilowatts (two through-circulation turbines with 315 kW every). 9.Zero m³/s can bypass the ability plant. In addition, floodwater in the higher Altmühl near Ornbau is diverted into the switch system, which is meant to protect 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 at the Hüttendorf gauge in dry situations. With the Danube-Important transfer, the water administration authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Main system in Franconia, which is threatened by momentary drought. There are additionally elements 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, together with the inlet and outlet structures, as well because the pumping stations on the south ramp.

Whereas in the name Major-Danube Canal the rivers in the word correspond to the geographical association on the north-facing map, the time period Danube-Predominant transition displays the stream course of the water pumped from the Danube and flowing within the course of the primary. Its longest tributaries additionally circulate into this decrease part of its course, particularly the Schwarzach, formerly additionally the Sulz, which has now been minimize up as a result of 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 right this moment Canal itself and eventually the Weiße Laber, all left-hand tributaries, whose nice size and catchment area reflects the rather 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 Important, which has been affected by intensive industrial and agricultural use. This brought with it vital restrictions on use and ecological dangers, e.g. B. for the removing of bank filtrate for irrigation of the Center Franconian vegetable growing space, which only grew to become doable with the transfer, or via using cooling water, etc. In the long term, a median annual switch through all the system of 150 million m³ of water is expected, 5/6 of that through the primary-Danube Canal. When water is low, water can be launched from the lake back into the Altmühl, but as a rule it’s initially transported from the Altmühlsee via the 8.7 km long Altmühl overpass, which crosses beneath 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 were sold this way annually. 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 additional inflow from the catchment space of ​​the Brombach turns into. In the years 1994-2013, a median of ninety seven million m³ of water have been transferred to the Rothsee yearly, the natural inflow of the small purple 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 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 positioned at the sports 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.
