Abstract
An apparatus is provided for supplying water to a conventional tree stand. A water level monitor is selectively positioned within the reservoir of the tree stand and is electrically connected to a solenoid valve so that water will be supplied from a water reservoir to the tree stand when the water level within the tree stand drops to a predetermined level. A float within the monitor drops with the water level, triggering a reed switch and activating the solenoid valve so that water can flow from a reservoir to the tree stand.
