Voting rules: Choose the thing found you think is the most unusual!
This is a community-based ranking of the most unusual thing found in the River Thames. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or discovery is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each discovery once every 24 hours. The rank of each discovery is then calculated from the weighted sum of all up and down votes.
