- Reasons for Decline in Water Level:
- Deforestation and unregulated construction in the surrounding areas have reduced the lake’s natural catchment capacity.
- Excessive extraction of groundwater has led to a decline in Balia Nala’s water flow, affecting the lake’s replenishment.
- Climate change and reduced rainfall have significantly impacted the water levels, leading to a five-year low of 4.7 feet.
- Encroachments and pollution from urban drainage and sewage inflow have further degraded the lake’s ecosystem, affecting its ability to retain water.
