Is it possible to have flooding conditions and yet still be in a drought?

MIKE MOSS SAYS:     It is very possible. Flooding results when too much rain falls in too brief a period for drainage systems (whether man-made as in pipes, culverts, ditches and the like,  or natural, as in streams, creeks and rivers) to carry run-ff downstream without water levels rising out of confined areas. While drought conditions do lower the likelihod of flooding for a given amount of rain, it does not preclude very high rainfall rates from producing a flood. Once the flood subsides, drought conditions may continue or resume if the heavy rain turns out to be an isolated occurrence.
