Flooding Continues in Navet, Tabaquite and Penal
9:00 AM Monday 23rd November 2020
Flooding is still ongoing across Tabaquite, in the vicinity of Navet as rivers remain at elevated levels in the area, particularly as both spillways of the Navet Reservoir are in use.
In Penal, at Ramdharry Trace, Clarke Road, flooding is also ongoing as water slowly subsides. The Caroni River is also at elevated levels but remains within its banks.
Navet Reservoir Spillway In Use For The First Time For 2020
For the first time for 2020 Wet Season, water levels at the lower Navet Reservoir became high enough that the spillway was utilized. This comes after 36 hours of persistent rainfall. Updated capacity numbers from WASA will be released this week.
The Navet Reservoir is the second-largest reservoir in Trinidad and Tobago, with a capacity of 19,100,00 m3 or just over 4.2 billion gallons of water covering an area of 800 acres.
Three streams have been dammed to form the Navet Reservoir. These streams flow from the nearby hillsides at Mt. Tamana, Brasso Piedra, and Chataigne (the latter so named after the chataigne trees that grow in abundance on its slope). The reservoir stretches out in several directions, to the foot of the distant hills. It forms an intricate pattern of inlets and coves, some as much as six kilometers (four miles) long
