Chennai's Hyacinth-Choked Vyasarpadi Canal Raises Fresh Flood Fears
A canal in Chennai is covered with a plant called water hyacinth and filled with some garbage.
This makes it harder for water to flow.
People living nearby are worried that heavy rain could make the canal overflow.
Some bridge construction has also blocked parts of the waterway.
Rainwater is already collecting in nearby streets.
The still water smells bad and may attract mosquitoes.
Residents want the canal cleaned quickly.
City officials say they are waiting for a robotic machine to begin removing the plants.
Water hyacinth and garbage have heavily blocked the Vyasarpadi canal near Shastri Nagar First Street.
Residents fear heavy rain could cause the canal to overflow and flood nearby homes and streets.
Bridge construction on Anna Salai has obstructed parts of the channel and slowed drainage.
Stagnant water has created foul odours, mosquito problems and concerns about vector-borne diseases.
The Greater Chennai Corporation has requested a robotic excavator to remove the vegetation and clear the canal.
