On August 4, 2020, works on the construction of a weir in Nowe Sady, in the Natura 2000 area "Mazurska Ostoja Żółwia Baranowo" PLH280055 were completed. A weir was built on the existing drainage ditch in order to keep the water in the ditch during the migration to the breeding sites of the female pond turtle Emys orbicularis. This action will improve the habitat conditions of this species.
