Lost black North Face backpack with water bottle pocket and patches at Meridian Park near picnic area.

I lost my black North Face backpack while I was at the Meridian Park during a weekend hike. It has a water bottle pocket on the side and a couple of patches on the front. It was filled with my water bottle, a first aid kit, and snacks. I last remember having it near the picnic area, but I can't find it anywhere. I really hope to get it back, as it has some personal items inside.
