Anuradhapura's ancient tank system faces critical water shortage

Water levels in 612 tanks throughout Anuradhapura have dropped to critically low levels, with most operating at less than 5% of their storage capacity, according to district authorities. The alarming decline reflects the severity of drought conditions affecting the region, which has experienced significantly below-average rainfall in recent months.

Anuradhapura's extensive network of ancient and modern irrigation tanks forms the backbone of agricultural activity in the district, supporting thousands of farming communities dependent on these reservoirs for irrigation during dry seasons. The current water shortage poses a significant threat to cultivation schedules and food security across the region.

District officials have warned that continued dry conditions could further exacerbate the situation, potentially affecting domestic water supply and livestock management. Authorities have appealed for immediate intervention to mitigate the impact on rural livelihoods and food production.

The situation underscores the vulnerability of Sri Lanka's agricultural heartland to climate variability and the need for sustained water management strategies. Anuradhapura district, home to some of the island's most historically significant irrigation infrastructure, faces mounting pressure to balance conservation with the demands of its farming population.
