Lakes by Tata. 17/03/89; Komárom-Esztergom; 1,633 ha; 47°30'N 018°17'E. Municipal Nature Conservation Area. The site comprises the Old Lake and the Által-ér river with smaller tributaries upstream, including varied wetland types rich in natural values and numerous remnants of the former extensive fen areas. The Old Lake, which is the largest lake of Komárom-Esztergom region, was created in the Middle Age with swelling up the Által-ér stream. It is an important habitat for migratory birds regularly supporting more than 25,000 waterfowl, especially Anser species, Anas platyrhynchos, and Larus ridibundus. Due to the natural conditions ploughlands and fishponds are the main land use activities, but the area is also wedged between urban and industrial regions as well as the urban agglomeration area of Tata. The main threat is expanding private land ownership and increasing plans for building activities. The implementation of fish ponds were the first, but not deliberate step towards the rehabilitation of the former wetlands. It is planned to develop further ecotourism and education facilities, e.g. a study trail with information panels. Significantly extended in 2006 and renamed from "Tata, Öreg-tó (Old Lake)". Ramsar site no. 419. Most recent RIS information: 200
