The lake reaches a maximum depth of 32 meters, making it the deepest reservoir in the region.
It is part of a complex water diversion system designed to channel water from the Danube basin to the arid Northern Bavarian region.
The MS Brombachsee is a unique trimaran vessel designed specifically for the lake's shallow shore areas.
The reservoir's creation required the relocation of the village of Enderndorf, which was subsequently rebuilt in a new location.
The dam embankment spans 1.7 kilometers in length and separates the Großer Brombachsee from the Kleiner Brombachsee.
Fishing is permitted in designated zones, with populations including pike, zander, and carp.
Winter ice formation on the lake is monitored, but public access to the ice is generally prohibited for safety reasons.
Großer Brombachsee is the largest reservoir in the Franconian Lake District, covering approximately 8.7 square kilometers. Completed in 2000 as part of a water management project, it serves both as flood protection for the Altmühl valley and a recreational hub. The lake is restricted to non-motorized watercraft, creating a tranquil environment for sailing and rowing. Passenger cruise ships, such as the MS Brombachsee, operate on the water for scenic tours. The shoreline features multiple sandy beaches, including those at Absberg and Pleinfeld. A circular path around the lake allows for extensive cycling and walking tours covering roughly 17 kilometers. Water quality is monitored regularly and maintains high swimming standards throughout the summer. The lake is connected via a dam to the smaller Kleiner Brombachsee.
The top of the main dam near the Absberg dike provides a panoramic view of the entire lake surface.
Bring polarized sunglasses to reduce glare on the water during midday hours.
Check the wind forecast before renting equipment, as the lake's size can create significant chop.
Visit the less crowded western shore beaches if you prefer a quieter swimming experience.
Avoid visiting on public holidays or weekends in mid-summer if you prefer solitude, as the beaches reach capacity.
Passenger ferry operations typically cease during the winter months when the lake may be prone to freezing.
Respect designated swimming zones and do not leave trash on the beaches; adhere to strict non-motorized vessel regulations.
