The site is located just southwest of Uthal, the district headquarter, and 95 kilometres from Karachi, near Sonmiani Bay.[1]
The lagoon is 60 km long and 4 to 5 km wide.[2] It mouth is 4 km wide.[2] Two seasonal rivers, Porali and Windor enter into this bay.[1] [2]
It is the only place in Pakistan where three species of mangroves, Avicennia marina, Rhizophora mucronata, and Ceriops tagal occur naturally.[1]
It faces two threats, namely domestic waste disposal and accumulated solid waste debris.[3]
