Framed watercolor landscape with gold frame

I lost my framed watercolor landscape yesterday around 7:30pm near the Water Street entrance to Phoenix Park in Eau Claire. It's a 16x20 inch piece under glass in a gold frame with a bit of chipping on the corners. The painting shows a sunset over the Chippewa River, with purple skies and a lone pine on the left; there's a small signature at the bottom-right that reads 'M. Rivera' and a faint coffee ring on the back. It has sentimental value—it was a gift from my late aunt, and I'm really hoping to get it back. If you've found it, please let me know through this listing so I can arrange a pickup.
