Lost silver flute with small scratches near the lake area in parks around Pierre, South Dakota.

I misplaced my silver flute while I was walking around the parks in Pierre last Thursday afternoon. I remember taking it out to practice a little by the lake and then realizing it was gone about 20 minutes later. It has a few small scratches but is otherwise in good condition. I'm really hoping someone could help me retrieve it as it's very meaningful to me.
