Yes any activity the disturbs the air/water interface will add DO to some extent. Rain , wind ,aeration , boat motor all do that. While rain does add DO it is not enough to offset the sudden die-off of large plankton blooms and the decomposition of same that uses up oxygen.


I was referring to the DO content of the actual rain drops, meaning that the drops are not void of O2, hence, the runoff that enters the pond is not void of O2 either. For what it's worth.
