Vishwamitri River Flood Mitigation Project

The Vishwamitri River in Vadodara, is undergoing flood mitigation project due to severe flooding in previous years. The Vadodara Municipal Corporation (VMC) has initiated a three-phase plan to desilt, dredge and modify the river channel, which includes crucial measures for relocating nearly 300 crocodiles residing in the area.

Project Details

• River Modifications: Straightening the meanders in certain sections and modifying the river channel to increase water-carrying capacity to 1,100 cumecs.
• Additional Structures: Construction of an additional spillway at Ajwa Dam and reduction of its crest level.
• New Buffer Pond: Creation of storage near Kotambi and Bhaniyara and dredging of ponds in Dhanora, Vadadala, and Haripura.
• Storm Water Network: Upgrading and diverting stormwater drains (e.g., Bhukhi kaans and Ruparel kaans) to reduce water flow into the city.
• Rainwater Harvesting: Installation of piezometers and flood-forecasting warning systems, and encouraging rainwater recharge.

Environmental Concerns

1. Crocodile Relocation:
   • The project includes the relocation of approximately 300 crocodiles (Schedule-I species under the Wildlife Protection Act, 1972).
   • This requires approval from the National Wildlife Board.
   • Scientific tagging and monitoring of crocodiles are necessary for relocation.
2. Impact on Wildlife:
   • Crocodiles, Indian Softshell turtles, monitor lizards, cobras, and Indian porcupines inhabit the river.
   • Disturbances from machinery and habitat alterations could agitate wildlife, pushing them toward human settlements.
   • The forest department recommends leaving nesting areas undisturbed and phasing work around the crocodile nesting season.

Recommendations for Wildlife Protection

Experts recommend leaving certain areas of the river undisturbed to allow for crocodile nesting. The VMC plans to create temporary shelters for relocated crocodiles, ensuring their safety during the project’s execution. The focus is also on maintaining the natural habitat for other species, such as monitor lizards and turtles.

Future Considerations

Ongoing monitoring of wildlife during and after the project will be essential. Scientific methods for relocation, including tagging, will help ensure that crocodiles can be safely returned to their habitats. The project marks the need for balancing urban development with wildlife conservation efforts.
