Is a 9ft 5wt ok for small streams?

[Chigimonky]

So I was hoping someone could give me some advice on a good size rod for fishing the provo down to something like the size of hobble creek. I just bought my first fly rod the other day and I got a good deal on it but it is a 9ft 5 wt and Im worried that it is going to be too big to fish the waters that I usually fish, like diamond fork or thistle creek or even parleys creek. I can take it back but they only had 7.5 ft and 9 ft rods in the price bracket that im comfortable with.

Any advice would be appreciated!
