Definitely send it!
When I was waitlisted by a school I sent in a letter outlining every single award, distinction, or even mild accomplishment I had mustered that spring. I got an acceptance call within 4 days of sending the letter!
It's not just about the award, but you're also showing them that you're really interested and really care about your fate with them.
