Cape Town Calls for Public Input on Zeekoevlei and Rondevlei Weirs Redevelopment

In an effort to bolster the ecological well-being of the False Bay Nature Reserve, the City of Cape Town has issued a request for comments regarding the planned upgrades to the weirs of Zeekoevlei and Rondevlei. These proposed changes are intended to complement the medium-term strategies already in place, such as the dredging of Zeekoevlei, targeting significant enhancements to the water quality of this site recognized by the Ramsar Convention for its global environmental importance.

The comprehensive upgrade and redesign plans cover the installation of mechanically operated sluice gates, replacing the current manual system, and lowering the weirs to allow for more effective water level management. This will significantly improve the annual 'drawdown', enabling the removal of excess nutrients and sediment that accumulate during the summer months. Historically, the waters of Zeekoevlei and Rondevlei were regulated with penstock sluice gates, a system that has been in place since the 1950s to regulate the movement of fish and to manage the risk of flooding in the surrounding areas.

Alderman Eddie Andrews, the Mayoral Committee Member for Spatial Planning and Environment, has highlighted the anticipated advantages, such as a more efficient process for drawdowns and improved water quality. Moreover, the modifications promise to bring back natural estuary fish species to these lakes, which will promote a richer and more diverse ecosystem. The reintroduction of indigenous fish is expected to restore the estuaries' role as nurseries for marine life and elevate the conservation status of estuarine-dependent species.

In recognition of the potential environmental impact these projects may have, an independent environmental practitioner has been tasked with conducting a thorough environmental impact assessment. This will ensure that all potential effects on the local ecosystems are understood and mitigated.

The City's call for public engagement underscores the importance of community involvement in environmental decisions. Residents and stakeholders of the False Bay Nature Reserve are encouraged to offer their comments and insights — a form of participatory environmental stewardship that is essential for the effective management of natural resources.

The deadline for submitting comments on the redevelopment project is set for 26 July 2024, providing ample time for public scrutiny and contribution toward these pivotal environmental upgrades.
