Abstract:
Recent increase in urban population, water pollution due to industrialization, and climate
changes revealed the need to revisit water utilization policies, to use water resources adequately,
redo critical analysis for existing prevention plans and prepare new prevention plans. In the
present study, current state of the water potentials of Eğirdir, Kovada regions, located at lakes
region, are investigated in terms of precipitation, temperature, evaporation, and water level
change by using the monthly and annual data available. Therefore, the data is processed by using
Run homogeneity test, Mann Kendall and Sen analysis. In addition, water budget analysis is
carried out for Lake Eğirdir. It is found that analysis results and water budget results overlap for
Lake Eğirdir. Provided that, preventive measures are not taken immediately, at the end of a 100-
year period. Level of Lake Eğirdir is estimated to decrease 24-%, annually. To prevent the water
level decrease in Lake Eğirdir, there are some necessary precautions should be taken-: (a)
Inactive underground resources should be activated,-. (b) Irrigation lands which use water from
Lake Eğirdir should not be allowed,-. (c) Future water storage within the rainfall watershed
should be prevented,-. (d) The lands that have shown no signs of development and expected not
to improve in the future should be detected and these lands should be removed from future
irrigation plans,-. (e) Efficient methods of economical use of water resources for the currently
cultivated irrigated lands should be explored and developed,-. (f) Throughout the use of
intelligent farming methods economic utilization of water should be performed. Concurrently,
there will be effects on Lake Kovada since Lake Kovada is controlled by Lake Eğirdir through a
water channel.
