Cornwall Canal Locks : Cornwall Canal

I saw what I think was an Otter with something in it’s mouth. It dived deep before I could take my nice camera out. A gaggle of Canadian geese could be seen together across the other side of the lock from which I sampled from. There were also fish swimming in the water which was clear for many meters down. There are plants under the water. It almost looked like a small patch of algae which I photographed. Many different plants could be seen in shore. The side which I stood was filled with goose droppings. The water flow was moving slowly, level average, colour as clear/deep blue as it got darker. There was no odour. I saw a fisherman also.
