Overview
- Local anglers and the Fischereiverein Holzkirchen issued warnings in late June that swimmers should avoid the shallow reed edge of the Dietramszeller Waldweiher where large European catfish are believed to have nested.
- Fisheries officials say Waller have lived in the pond for about 50 to 60 years and that a 2.09‑metre specimen was reportedly caught two years ago, making fish over two metres plausible.
- The greatest risk is limited to the reed fringe, which is about 70–80 centimetres deep, while the central bathing area is roughly two metres deep and considered low risk by the association.
- No attacks have been reported at Dietramszell, but the warning follows public sensitivity after last year’s Brombachsee incident in which a large Waller injured swimmers.
- The pond is drained for maintenance every five to seven years and this year‑end draining will allow anglers to catch and measure fish, giving definitive data on Waller sizes and numbers and guiding future safety advice.
