A low water level indicator includes a detection assembly and an indicator unit. The detection assembly comprises a housing, a pair of electrodes, a control unit, and a battery. The indicator unit comprises a light emitting diode (LED) and a base. The housing is preferably molded as two halves which are joined at assembly. An adjustment rod is held by a first and second snap retainer at substantially the bottom of the housing. The adjustment rod is used to adjust the height of the bottom of the housing relative to a water container. The electronic control circuit is mounted in a top cavity. A hook rod is held by a top spring clip which is disposed at substantially the top of the housing. The hook rod is used to provide stability for the placement of the detection assembly. A second embodiment of the low water level detector utilizes at least one eye loop projection and a filament means to suspend the detection assembly from a tree. When the water level in a water container is too low, electrical current will no longer pass from the first electrode to the second electrode through the water. When current flow ceases between the first and second electrode, the LED will emit light until the water level is raised.
