Cleaning and maintenance of Jonkershoek weirs
The SAEON Fynbos Node monitors long term change in the run off of water from mountain catchments at
Jonkershoek. The Jonkershoek Experimental Catchment consists of six weirs on streams within the Jonkershoek
reserve and forestry area. The weirs form part of a long term catchment monitoring programme which was
established from 1938 onwards to measure streamflow under various land uses. This programme supported the
establishment of the Working for Water programme by providing data on water use by alien woody plants compared
to indigenous vegetation in catchments and the award of Forest Stewardship Certification for South African
The weirs continue to provide valuable data in terms of impacts of climate change on catchment water delivery and
how this may impact the environment downstream of catchments. They improve our understanding of the impacts
of a range of global change factors on the hydrological cycle which improves our ability to manage catchments for
sustainable water delivery.
The monitoring weirs are in need of cleaning on an annual cycle to maintain accurate measurement of stream flow.
2. Performance specifications
2.1 Objective and Purpose
This call is for cleaning and maintenance of the Jonkershoek experimental weirs in order that they continue to deliver
quality data. The cleaning of the weirs ensures accurate measurements of stream flow. The maintenance of the
weir structures when the weirs are emptied for cleaning ensures the continued integrity of the structures.
2.2 Outcomes to be achieved
In consideration of the above needs, the project will need to achieve the following results:
Clean weir ponds
Clean stilling wells
Clean and repaint weir notches
Removal of a dead tree overhanging one weir
Re-greased plugs in all drainage holes
