No.
To determine if "predicate adjective" is being used in the sentence, let's break down the sentence and understand its parts.
The subject of the sentence is "water," and the verb is "rose." Here, "rose" is a linking verb that connects the subject "water" to the complement "almost to the top of the dam." The complement provides additional information about the subject.
Now, in this case, "almost to the top of the dam" functions as an adverbial phrase modifying the verb "rose." It describes how high the water rose.
Therefore, there is no predicate adjective in this sentence. A predicate adjective would be an adjective that describes the subject and follows a linking verb.
