Comments
all debris collected from the riverbed that had been there for a few months already was completely covered in fresh water mussels. These were removed out of the water with the debris and could not be released again. They live in the local rivers in abundance and are mostly invasive so a release was not necessary.
In summer this spot is very popular for a river walk and some beers on the pier. Also the public and tourist boats around that area are contributing to the debris issue. Furthermore the bridge crossing the river at this point is very popular for discarding stolen wallets so we always find some wallets and credit cards in this area.
This bridge and area is also one of the main spots for all large events in Zürich such as the "ZüriFescht" or "Streetparade"
- desk chair with unicorn design
- baby carriage
- piggy bank
Any type of bottles (glas bottles, PET plastic bottles, aluminum cans) - Main source of debris in this area
stolen and discarded items such as empty wallets , credit cards , phones
rental e-scooters, since they also have very harmful batteries attached to them
Comments and Feedback
This event was sponsored by TSK Zürich and ERZ Zürich! the entire event was a huge success despite snow rain and the cold. We had about 22 active and tireless divers who collected insane amounts of debris from the riverbed during multiple dives throughout the event as well as 10+ participants for land support who weighet, identified, counted the data.
THANK YOU FOR ALL OF YOUR SUPPORT!
