The Nadela or Nadel (Serbian Cyrillic: Надела or Надел) is a system of canals and rivers in northern Serbia, an 84 km (52 mi)[1] long left tributary to the Danube in the Banat region of the Vojvodina province.

This is just the first of the many sluice gates on the river's course (Tomaševac, Uzdin, Putnikovo, Kovačica, Debeljača) which channel the waters into the southern direction.

A series of sluice gates serve for several purposes: In early 2016 a group of local enthusiasts and fishermen organized in an attempt to clean the area of Nadela between Starčevo and Omoljica.

Number of protected birds in the surrounding area dwindled, while a rare local subspecies of southern festoon, which regularly appeared once a year, is no more.

Some one hundred Siberian elms were planted around the revitalized area, which also includes four water springs, river island in Nadela which covers 0.4 ha (0.99 acres), and scenic viewpoints.
