Concerns grow over leak near dam wall at Vleiloerie Bird Sanctuary
Mogale City Local Municipality (MCLM) responded to growing concerns over a leak near a dam wall at the Vleiloerie Bird Sanctuary.
While a leak near a dam wall at the Vleiloerie Bird Sanctuary is a growing concern to some in the community, the municipality indicated there is no reason to panic.
Just recently, a resident approached the News expressing deep concern about the situation.
“I have been reporting a leak nearby the dam wall since June 18 – first to a councillor and from there I have been sent from pillar to post. Vleiloerie is supposedly a bird sanctuary. Why is nobody concerned about the birds and fish and whatever else. Just a sign of the times?” the resident asked.
Mogale City Local Municipality (MCLM) meanwhile responded saying they are well aware of the situation.
“An inspection on September 21 was conducted by the Environmental Protection Division and discovered a corroded valve as the cause of the leak towards the Vleiloerie Wetland System,” said Assistant Manager: Environmental Protection Stephan du Toit.
He added, “The constant feed via the corroded valve to the wetland system is actually very good for wetland functioning, goods and services, since the wetland suffered historically due to the water that originates from an upgradient spring is being trapped behind the dam wall. The water levels in the dam were historically never regulated, which resulted in wetland functioning that is compromised during winter or prolonged periods of no rain.
“As you are aware, the goods and services offered by the Vleiloerie Wetland System are necessary to ensure flood attenuation to protect the Johan Jonker Drive and associated road infrastructure, as well as improved water quality in the Centenary Dam.
“Our Environmental Protection and Storm Water Divisions will conduct a joint inspection to verify if a valve replacement can be done and then to arrange for controlled release of water from the dam as and when required.”
Regarding the well-being of the fish, Du Toit said, “The water level in the dam has significantly restored after the recent rain [110mm for October 2022] and there is no reason for any concern for the fish. The concern should be more for pollution emanating from storm water from Voortrekker Road and uncontrolled access [for 4×4 activities, religious ceremonies and rituals; illegal fishing; etc].”
