Nuwara Wewa, Anuradhapura
Nuwara Wewa (Sinhala: අනුරාධපුර නුවර වැව) is a reservoir situated in Anuradhapura District, Sri Lanka.

This has been identified as the ancient "Nakara-vapi" tank that is recorded in the Thuparama Slab Inscription of King Gajabahu I [(114-136 A.D.) Arumugam, 1969; Nicholas, 1963; Paranavitana, 1933]. It was enlarged, improved and added a feeder channel from Nachchaduwa Wewa during the reign of Moggallana II [(535-555 A.D.) Arumugam, 1969].

The present tank was restored in 1890 (Arumugam, 1969).

The reservoir
Except for the drainage from its own catchment area, the reservoir is fed by an ancient channel from the Nachchaduwa tank (Arumugam, 1969). The bund of the reservoir is about 4.25 miles long and the water is extending in an area of about 3,000 acres at its full supply level (Arumugam, 1969). It has two spills and two sluices (Arumugam, 1969).
Ancient sluice 
As recorded by Parker in 1909, there was an ancient sluice at Nuwara Wewa (Paranavithana et al., 2020). However, it was demolished by the British later to construct new structures (Paranavithana et al., 2020).
