The Nová Řeka canal (New River) connects the Lužnice and Nežárka rivers south-west of the town Jindřichův Hradec in the area between the town Třeboň and the small town Stráž nad Nežárkou. It was built for the regulation of the Lužnice river's inflow to the Rožmberk pond.
It was built between 1585 - 1587 by Jakub Krčín, the administrator of Rožmberks' domain. The canal drains excessive water from the Lužnice river into the Nežárka river and protects the dam of the Rožmberk pond from overloading. It branches off from the Lužnice river about 5 km behind the village Majdalena about 10 km south-east of Třeboň and it runs to the north all the way. It is 14 km long and it flows into the Nežárka river about 4 km west of Stráž nad Nežárkou.
The Nová Řeka canal feeds several ponds around Třeboň, but its basic function is to deviate water from the Lužnice river into the Nežárka river.
The red marked trail leads along the canal between the small village Stříbřec (about 6 km east of Třeboň) and
