After devastating pollution, Thérain is reborn: “We are creating the first fishing reserve in Beauvais’. Between the Boileau Tower and the Paris Bridge, part of the river will become a nature reserve.

Five other restocking operations will be scheduled between now and August. “Don’t dump them all in the same place, otherwise they will stay together,” advises Alain Ridel, fishery warden. And a few hundred meters from where they were dumped, they will find a protected area where fishing will be prohibited.
