The lake is well known for attracting the less commoner species like Slavonian Grebe (Horned Grebe), Black-throated Diver (Arctic Loon), Red-throated Diver, Velvet Scoter and Red-breasted Merganser. Naturally, if you want to visit the whole area, you can spend a full day of birding in the area. If your time budget is limited focus on the small village Ramsberg on the southern shore, which is in my opinion the best position. In case you have more time at hand, view below the section "Birdingplaces nearby" where I've added some other rewarding places around the lake.
In Ramsberg you can park your car at the end of the "Untere Dorfstraße" and follow the path to the shoreline. From here the eastern half of the lake can be overlooked. Walking the path to the left you reach soon a good viewpoint for the western part. Furthermore, around the marina closeby (follow the Leitenbuckstraße the centre of the village to reach a big car park outside of the village) Red-necked Grebe, Goosander and Gulls ( Yellow-legged Gull, Caspian Gull and Common Gull) are found regularly.
The national route B2 runs close to the eastern shore connecting the area with the motorway A6 in the north (exit Roth). Coming from the south leave the A9 at Hilpoltstein and follow afterwards the signposts to Heideck and Pleinfeld.
Ramsberg has a train station, as have also Langlau and Pleinfeld. If you consider to visit more than just one position a car is indispensable.

Other suggestable viewingpoints (I refer to Christoph Moning, Christian Wagner: Vögel beobachten in Süddeutschland, Stuttgart 2012) around the lake:
The eastern shore which is approachable from the car parks of the Freizeitanlage Allmannsdorf and the Freizeit Pleinfeld Süd.
The Kleiner Brombachsee: can be overlooked from a car park along the road between Langlau and Absberg.
Furthermore advisable is the car park of the Freizeitanlage Seespitz (pay attention to the small signpost in Absberg). From there you can walk either to the dam between Großer and Kleiner Brombachsee or to the tip of the peninsular.
Finally, Enderndorf on the northern shore is offering a good view.
Other rewarding sites nearby are the Altmühlsee and the Rothsee.
