From the context of the sentence, it is clear that the announcement took place only after the level of the river did not rise as desired. This is the reason why the announcement was made. Hence, to establish proper sequencing between these two related events, we use past perfect tense for the event that took place earlier - had resulted. Now, the intermittent showers fell the day before. Because the showers were intermittent, the level of the river did not increase as desired. So these two events are also related.
