The beneficial effects of the water retention investments implemented by the West Transdanubian Water Directorate (NYUDUVIZIG) a few weeks ago are already visible on the Marcal River and the previously completely dried-up Merseváti Peat Mine. The Merseváti Peat Mine Association owns its own fishing water, the water balance of which is closely related to the water level of the nearby Marcal River. The increasingly severe drought periods of recent years have significantly affected both water areas, and this summer the lake completely dried up, which unfortunately also resulted in the death of the fish population. Our Association initiated negotiations with the NYUDUVIZIG leadership in late autumn 2025. The leaders of the Water Directorate said that the examination of interventions aimed at improving the condition of the Marcal is underway, and the idea of implementing bottom sills also came up during the negotiations. The leaders of the Water Directorate promised at that time to examine possible technical solutions and look for the possibility of intervention. To our great joy, the promise was followed by concrete measures. This year, the specialists of NYUDUVIZIG prepared the necessary plans, obtained the water rights permits, conducted the official and nature conservation consultations, and then implemented the investments to help retain water in the Marcal from state budget funds. In the Szergény and Mersevát areas, stone sills with a close-to-natural design were built, the purpose of which is to support the water level of the river, keep the water in place, and improve the groundwater management of the surrounding areas. The technical handover of the second phase of the developments will take place next week.
