Residents around Lake Victoria have recently complained of a persistent foul smell emanating from the lake, particularly near Murchison Bay. The Ministry of Water and Environment has released an official statement explaining the causes of this unpleasant odor and outlining urgent measures needed to address the issue.
Lake Victoria, Africa’s largest freshwater lake, is a critical resource for Uganda, supporting over 38 million people for drinking water, transportation, and trade. However, Murchison Bay, a shallow and heavily utilized shoreline near Kampala, has become a hotspot for pollution.
According to the Ministry, the foul smell is primarily due to:
- Excessive Algal Growth – High levels of nutrients (nitrogen and phosphorus) from sewage, industrial waste, and agricultural runoff have triggered massive algal blooms, turning parts of the lake green.
- Decomposing Algae – When these algae die, they sink and decompose, consuming oxygen and releasing toxic gases like hydrogen sulfide and ammonia, which produce the rotten-egg-like stench.
- Low Oxygen Levels – The decomposition process creates “dead zones” where fish and other aquatic life struggle to survive.
The problem worsens during high temperatures and windy conditions, spreading the odor across nearby communities.
Major Pollution Sources
The Ministry’s Water Quality Monitoring Network, which includes 21 stations in Kampala and 10 in Entebbe, has identified key pollution contributors:
- Untreated sewage from Kampala and surrounding areas.
- Industrial discharges containing harmful chemicals.
- Plastic and solid waste dumped into the lake.
- Agricultural runoff carrying fertilizers and pesticides.
- Destruction of wetlands, which would normally filter pollutants before they reach the lake.
To combat the crisis, the Ministry has outlined the following measures:
1. Restore Wetlands and Enforce Buffer Zones
- Rehabilitate degraded wetlands to naturally filter pollutants.
- Strictly enforce the 200-meter buffer zone around the lake as per the Environment Management Act to prevent further encroachment.
2. Improve Waste Management
- Upgrade sewage treatment plants to prevent raw wastewater from entering the lake.
- Enhance solid waste collection to reduce plastic and organic pollution.
3. Regulate Industries and Farms
- Industries must adopt cleaner production methods to minimize toxic discharges.
- Farmers should use eco-friendly practices to reduce chemical runoff.
4. Strengthen Law Enforcement
- Local authorities must crack down on illegal dumping and enforce environmental laws.
5. Public Awareness Campaigns
- Educate communities on sustainable practices to protect the lake.
- Encourage citizen participation in conservation efforts.
The foul smell plaguing Lake Victoria is more than just a nuisance—it’s a dire warning of ecological collapse. The Ministry’s proposed measures offer a roadmap for recovery, but swift and coordinated action is essential.
