Abstract
Watershed is the territorial field which is separate from each other hydrologically, forming water’snatural borders, on which, water continues its surficial movement. In the phase of planning and managing thewater, the hierarchal structure (main river watershed, subwatershed), borders and qualities of these territorialfields are quite important. In this study, the borders of Kovado Lake Watershed were defined with the Arc HydroModule. This method intends to reach the watershed borders in 10 phases (DEM reconditioning, Fill sink, Flowdirection, Flow Accumulation, Stream Defination, Strean Segmentaition, Catchment Grid Delination, CatchmentPolygon Processing, Drainage Line Processing, Drainage Point Processing). The analysis results concerningthe Arc Hydro Module shows that Kovada Lake and Eğirdir Lake are located in the same subwatershedssystems. In this case Kovada Lake Subwatershed should be considered as one of the subwatershed of EğirdirLake SubwatershedKovada Lake Subwatershed has approximately 184.410.000 m2 area, 214.800 m circumference. It also has 13water gathering areas, 13 drainage points. The total length of the drainage networks are 77.489 m. The ArcHydro Module helped to reach quite important results in gaining the basic data (watershed border, drainagesystem, etc.) about the watershed.
