Drying Dorabeel–Kulsi Channel Threatens Dolphin Survival
A channel that connects Dorabeel wetland and Kulsi river is drying up, which is bad news for the Gangetic river dolphins that live there.
These dolphins rely on the channel for food, as fish from the wetland swim through it to the river.
But now, the channel is almost dry, and the fish aren't moving as they should.
This is making it hard for the dolphins to find food.
Scientists and local people are worried that if the channel isn't fixed, the dolphins might not survive.
Some people think that the channel is being blocked by vehicles, which is making the problem worse.
They want everyone to work together to save the channel and the dolphins.
The Dorabeel–Kulsi channel connecting the Dorabeel wetland and Kulsi river is drying up, threatening the survival of Gangetic river dolphins.
The channel's reduced water flow has halted fish migration from the wetland to the river, which is crucial for the dolphins' food supply.
The channel's depth has significantly decreased from up to 4 meters during the rainy season to almost defunct now.
Scientists warn that the channel's condition is critical for the conservation of dolphins and their habitat.
Local residents allege that the channel is being blocked by earth-laden vehicles, contributing to sedimentation and further deterioration.
