A poisonous plant northern water hemlock (cicuta virosa) has been observed along the shores of Kymijärvi, including at the Karisto swimming beach and boat docks, Kaukkari boat docks, and at the end of Karisto canal boulevard. The plant has not been observed in the swimming area at Karisto beach, so swimming there is still safe.
The city of Lahti has marked some of the affected areas with caution tape and notices, and will mark the remaining observations during week 32. Control measures will be implemented later in the fall, after the swimming season ends, to prevent contamination of the water from the removal of the plants.
