Abstract:
Ecological impacts of reservoir have been reported from various aspects such as barrier for migratory animals, eutrophication of reservoirs by plankton blooming, decreasing flow volumes in tail waters, stabilization of flow regimes by flood peak cut, changes in thermal regimes of river water. Dam lakes also effects climatic specifications as temperature and humidity on region. Altough unfavorable effects, dams have a potential as recreation fields, energy, turistic activities etc. It is possible to happen changes in Ermenek region as what kind of effects has seen in area of huge dam lakes. The study tries to determine the climatic effects of Keban Dam, Ataturk Dams and Ermenek Dam by using the data extracted from near meteorology stations. Although there was no statistically significant change on climatic characteristics, the dams caused a partial alteration in humidity and temperature values. Relative humidity has increased in all months and years after the dam in Ermenek. While the yearly average relative humidity was 47,5% before the dam (average min. %33,4 in July, max. %60,3 December), it has reached to 62,9% by rising each month and year after the impoundment. The increase in humidity will likely reduce the frost damage in terms of frost frequency, intensity and time. 30 hectares of 34.5 hectares irrigated land remained underwater and was expropriated for the Ermenek Dam. If the benefit created by the Turquoise lake will evaluate, economic losses can be compensable.
