Lost gray hiking backpack with bright orange rain cover near Columbia River Park trails in Wenatchee.

I lost my gray hiking backpack on the trails near Columbia River Park in Wenatchee. It has several compartments, a bright orange rain cover, and a pocket for a water bottle on the side. I realized it was missing after stopping for a break near the river. If anyone has seen it or has found it, I would appreciate any help in getting it back!
