Coons are common around any water source. Coon tracks are easy to recognize by their long fingers & are smaller than a grown otters track. An otter track will be somewhat similar to a medium size dogs but will have 5 sharp pointed toes (dogs have 4). They lope when they travel so will leave a pattern similar to a rabbit in snow.
Here's some tracks:
