Abstract
Signaling methods and apparatuses are described for preventing flood irrigation water from overflowing in a trench, field, or other area. Signaling devices may include indicators such as a reflector, a flag, a light, or a sound device provided on an end of an elongate member having its opposite end engaged with the ground. A stake is driven into the ground near the elongate member in the trench or other area where water will flow. A breakaway link such as a strip of paper is engaged to either the indicator or the elongate member and also to the stake, causing the elongate member to be bent downward, with the breakaway link located in the trench where water will flow. When exposed to the flow of water, the breakaway link weakens and eventually tears such that the elongate member springs upward carrying the indicator with it, signaling an operator that water has reached that location in the trench.
