Fish in Creek Nov. 11, 2018

What I saw on my morning walk at 20 degrees F.
Almost all of the fish in our creek are Brook Trout except in the fall we do see spawning Brown Trout. You usually see white tips on dorsal fins on Brookes but it's hard to see in this light this morning. Could it be a small Brown? I doubt it as most of the Browns I see here in fall are twice this big.
