As defined by the Irrigation Department, small tanks are those, which irrigate land extents of 80 hectares or less. Systematic studies so far undertaken, among others, Tennakoon (1974, 1986) and Panabokke (1999) have revealed that there is a tank for every 1.5 sq. km. in the Rajarata. Panabokke's study (1999) further reveals that there is a similar density of tanks in the northern part of the Kurunegala District as well. According to the same study, there are about 15,500 small tanks in the Dry .Zone and approximately half that number of tanks remain either dilapidated or abandoned.
