I hope Zibi can do something fun with this canal, assuming it can be done safely.
In the summer, you could build some kind of protected swimming pool with a small wooden beach on the right.
In the winter, hang some string lights above it, setup some chairs/tables and heaters, and you got a nice skating rink directly connected to a ski trail.
With many people moving into Lebreton flats and nothing like that within 3km distance, it could be a hit with a relatively small investment.
