Habitat Restoration Measures
The Wullar-Manasbal Development Authority (WMDA) has implemented several restoration initiatives.
Targeted Dredging
Dredging has helped:
- Restore natural water circulation
- Increase water depth
- Remove accumulated sediments
Weed Removal
Excessive aquatic weeds have been removed to:
- Improve oxygen availability
- Enhance aquatic biodiversity
- Facilitate better water flow
Together, these measures have significantly improved the ecological health of the lake.
Hydrological Management
To ensure sustainable water management, the Jammu & Kashmir Water Resources Regulatory Authority is undertaking water budgeting.
Objectives of Water Budgeting
- Assess the lake’s carrying capacity
- Evaluate current water withdrawals
- Estimate surplus water availability
- Maintain ecological water balance
Supporting infrastructure includes:
- Mechanized gates
- Gauge meters
- Continuous monitoring of water levels
These measures help maintain optimal ecological conditions throughout the year.
Pollution Mitigation Measures
A comprehensive pollution control strategy has been introduced.
Sewerage Treatment Plant (STP)
The STP treats wastewater before it enters the lake, reducing pollution.
Solid Waste Management
An integrated waste management facility helps prevent the accumulation of solid waste around the wetland.
Trash Guards
Trash interception systems have been installed near the Lar Irrigation Canal to prevent:
- Plastic waste
- Floating debris
- Domestic effluents
from entering the lake.
Community-Based Conservation
Local participation has become a key component of restoration efforts.
Major initiatives include:
- Celebration of World Wetlands Day
- Bird-watching festivals
- Environmental awareness campaigns
- Promotion of eco-friendly tourism
- Community involvement in conservation activities
These programmes encourage sustainable use of the wetland while reducing human pressure on the ecosystem.
