Tha Faek (Thai: ท่าแฝก, in Thai pronounced as /tʰâː fɛ̀ːk/) is a tambon (sub-district) of Nam Pat District, in Uttaradit Province, Thailand. In 2014 it had a population of 4,434 people.[1]
The sub-district originally was part of Tha Pla District. With the creation of the Sirikit Dam in 1972, the sub-district has become separated from the central part of Tha Pla District. Effective 14 February 2015, the sub-district was reassigned to Nam Pat District to make the authorities easier to reach for the local residents.[2]
The sub-district is divided into nine administrative villages.
