What is THAT Swimming in Clear Lake?

WHAT is THAT Swimming in Clear Lake?

Lately, sitting on the balcony overlooking the lake, my eye was caught by ripples from a strange creature that came into view. Most of it is below the surface b,ut you can tell it is a big creature compared to what you usually see on the water (where kids where sledding behind a boat yesterday).

Only a small part protrudes above the water. It doesn't dive or look like a duck or anything else I've seen on the lake.

It slowly swims along the shore of Clear Lake. An eel? A gator? Just WHAT is that thing?

This morning I ran and got some video of it (the sun wasn't up yet so it is dark). Notice how the water forms a curve when it turns in the second video as it neared some docks.

We used to have small ducklings (actually Cormorants?) of over 30 swimming together in a group. Now I see about 5 or 6 in a group.

It's enough to give one a pre-existing condition. Hope the ducks don't get their policies cancelled for reaching their policy cap!

WHAT is that thing? Umm.
