|Project summary=The Zuidelijk Afwateringskanaal water body is classified under the WFD system as M1a: buffered ditches. The entire water body is managed by water authority Rijn en IJssel. The Zuidelijk Afwateringskanaal is partly located in the province of Gelderland (municipality Berkelland) and partly in the province of Overijssel (municipality Hof van Twente). The water body is 10.7 km long and has a catchment of 4449 hectares. The Zuidelijks Afwateringskanaal is an engineered waterway. It discharges into the Twentekanaal. Water levels are managed with four adjustable weirs (one automatic) and five fixed weirs. None of these weirs are passable for fish. In this water body, a single minimal water level is pursued for each managed stretch, for which the weirs are used. The water body does not carry water all year long. In dry periods, the 24 upstream stretches of the water body run dry. The Zuidelijk Afweteringskanaal is mostly there for drainage. Water is being let into the water body from the Bolksbeek in dry periods. There are no sewage treatment plants present in this catchment. | |||

Project summary
The Zuidelijk Afwateringskanaal water body is classified under the WFD system as M1a: buffered ditches. The entire water body is managed by water authority Rijn en IJssel. The Zuidelijk Afwateringskanaal is partly located in the province of Gelderland (municipality Berkelland) and partly in the province of Overijssel (municipality Hof van Twente). The water body is 10.7 km long and has a catchment of 4449 hectares. The Zuidelijks Afwateringskanaal is an engineered waterway. It discharges into the Twentekanaal. Water levels are managed with four adjustable weirs (one automatic) and five fixed weirs. None of these weirs are passable for fish. In this water body, a single minimal water level is pursued for each managed stretch, for which the weirs are used. The water body does not carry water all year long. In dry periods, the 24 upstream stretches of the water body run dry. The Zuidelijk Afweteringskanaal is mostly there for drainage. Water is being let into the water body from the Bolksbeek in dry periods. There are no sewage treatment plants present in this catchment.
The water authority adapted its mowing regime in this stream to main channel mowing, mainly to get more experience with this vegetation removal strategy.
Monitoring surveys and results
Backwater effects and vegetation regrowth are being monitored. Results are not yet known.
