ABSTRACT:
A flood warning system including a stilling well having three vertically spaced apart float switches therein for detecting the level of flood waters. Upon the water level reaching and closing the lowest float switch, a telephone alarm dialer is actuated to transmit a first low stage flood warning message to a remote location. Upon the water level reaching and closing the second or middle level float switch, the lowest float switch is disabled and the upper float switch is enabled. Upon the water reaching and closing the upper float switch the telephone alarm dialer is actuated to transmit a high stage flood warning message to the remote location. As the water recedes, upon dropping below and opening the middle level float switch the lowest float switch is enabled and the upper float switch is disabled thereby actuating the telephone alarm dialer to transmit a second low stage flood warning message to the remote location. This second low stage flood warning message indicates that the flood has crested.
