An ice tray with water level detecting device includes an ice trench and a water level detecting device for detecting the water level of the water in the ice trench. The water level detecting device includes a radio frequency detecting device and a parameter setting unit. The radio frequency detecting device emits a radio frequency wave to the ice tray and the water and receives the reflection wave from the ice tray or the water. Here, the radio frequency detecting device has a decision level for deciding the strength of the reflection wave, so as to output a stop signal to stop the water supplying schedule. And, the parameter setting unit can alter the decision level for changing the water level of the ice tray. Therefore, through the structure described above, the water amount in the ice tray can be detected and controlled in an effective way.
