Lauser Weiher closed: Fight against dangerous creepers runs!

Lauser Weiher closed: Fight against dangerous creepers runs!

The Lauser Weiher, a picturesque, moor -containing swimming lake in the Kupferbach valley, is again the focus of the public. The popular bathing lake is currently closed due to a heavy creeping plant infestation. Mayor Peter Wagner (CSU) informed the local council about the unpleasant situation and the previous measures to combat aquatic plants. Several attempts, including the use of Biolit stone flour in 2024, did not have the hoped-for effect.

The creeping plants are not only an optical problem, but can also be a security risk for bathers. As the German Life Rettungs Society (DLRG) reports, such plants are often associated with bathing accidents. While these plants do not actively pull swimmers down, they can lead to panic reactions that can lead to dangerous situations on the water. This topic clouds the anticipation of the bathing season considerably.

control measures on the Lauser Weiher

A mowing boat is in use to reduce the growth of the creepers. The cut aquatic plants are then temporarily stored on the bank and disposed of in an environmentally friendly way. In addition, it is considered using grass carp. These should help to ensure that the problem does not worsen further. The cooperation between the municipalities of Feldkirchen-Westerham and Aying as well as the owner and tenant of the pond shows that one is willing to invest in joint measures for a long-term solution.

Algae control started in April 2024 in the Lauser Weiher. Biolit stone flour, a natural fabric that is environmentally friendly and has no harmful effects, was used to combat algae. This treatment shows positive results in other waters and aims to restore the ecological health of the pond. Interestingly, Biolit can even be used during the bathing business, despite a temporary clouding of the water, which is harmless to humans and animals.

The risks of the creeping plants

The dangers that go from creeping plants should not be underestimated. As it becomes clear in an incident at the Silbersee near Hanover, panic reactions can lead to tragic accidents. The DLRG emphasizes that swimmers often panic when touching aquatic plants and these reactions, not the plants themselves, make up for dangerousness. In order to deal safely with creeping plants, the DLRG advises: keep calm, plants from the body parts strip and remain flat on the water surface.
