ABSTRACT:
A water gauge in accordance with the invention includes a base and a spherical indicator ball. The base includes a container having a side wall, a bottom wall and a post. The spherical indicator ball has a yellow initial signal hemispherical wall and a red final signal hemispherical wall connected to an axle along a circumference. The axle is supported by the side wall of the container. The yellow initial signal hemispherical wall is heavier than the red final signal hemispherical wall. The spherical indicator ball has a channel in the middle of the red final signal hemispherical wall. Initially, the post is positioned into the channel so that the yellow initial signal hemispherical wall is up and visible. The water gauge is positioned on a lawn to be watered. When watering has added a sufficient amount of water to the container to float the ball above the top of the post, the ball is rotated by gravitational force to position the heavier hemispherical wall in the water. Thus, the water gauge is adapted to indicate when water droplets falling onto a lawn have reached a predetermined amount.
