I spotted this almost ground level rainbow in the park near my house a few days ago. There was a fire truck nearby that was squirting a tall column of water into the air (for what purpose, I don't know). The water was falling into the lake in the form of a fine mist visible as a white cloud in the picture. The rainbow had formed in the mist right above the lake below the grassy slope.
As I was getting my companion positioned in the scene to get a photo of her with the rainbow, the firefighters shut off the water and the rainbow was no more.
