Lost bright red dog collar with blue name tag near Lake Butte des Morts park in Appleton-Oshkosh-FDL area.

I recently lost my dog's collar in the Appleton-Oshkosh-FDL area at the park near Lake Butte des Morts. It's a bright red collar with a blue name tag that has my phone number on it. My dog, Max, was playing in the water when I noticed it was gone! If anyone finds it, I would really appreciate it if you could reach out.
