Tabbowa Wewa |
Tabbowa Wewa (Sinhala: තබ්බෝව වැව) is a reservoir situated in Puttalam District, Sri Lanka.
History
The area where the present Tabbowa Wewa is located belonged to the ancient Tabba-rattha, the most westerly frontier district of King Parakramabahu I's (1153-1186 A.D.) 12th-century principality of Dakkhinadesa (Nicholas, 1963). Parakramabahu I is said to have restored this tank (Nicholas, 1963).
The restoration works of the present tank commenced in October 1912 and were completed in 1925 (Arumugam, 1969). It was enlarged and improved in 1969 (Arumugam, 1969).
The Reservoir
The reservoir has been constructed by damming the Nanneri Oya, a tributary of Mi Oya (Arumugam, 1969). The bund of the reservoir is about 1.25 miles long and the water is extending in an area of about 1,500 acres at its full supply level (Arumugam, 1969). It has one spill and two sluices (Arumugam, 1969).
Tabbowa Basin Fossils
Two small occurences of Jurassic sediments are found preserved in faulted basins within the Precambrian basements in the north western part of the country at Tabbowa and Andigama (Fernando, 2012). Since the early 20th century, numerous well-preserved plant fossils have been recorded from the Tabbowa basin which is partly covered by the Tabbowa tank (Chang et al., 2017; Tantrigoda & Geekiyanage, 1991). The Tabbowa beds are exposed on the surface within and around Tabbowa Wewa, especially below the tank bund and in channel-cuts (Fernando, 2012).
