In the village of Pago Pago, from Malaloa to Satala, there are a total of eleven rivers or streams. These include Vaipito, Gagamoe, Laolao, Pago, Leau, Vaima, Utumoa, and Aga. Tidal mud flats associated with the mouth of the Vaopito Stream were filled in order to create Pago Pago Park at the head of Pago Pago Harbor. Five species of Gobie fish, Mountain bass, Freshwater eel, Mullet and four shrimp species have been recorded along the lower reach of the Vaipito Stream. One of the Goby species, ''Stiphodon hydoreibatus'', is endemic to the Samoan Islands and found nowhere else on Earth.
