The lake is divided into four distinct parts. The southern part opens by a 380 m wide strait to the Gulf of Thailand at the city of Songkhla, and contains brackish water of about half the salinity of the ocean. To the north the water changes to sweet water. Further north after a bottleneck of only 6 km width is the "Thale Luang" (782.80 km²), and finally at the northern end in between a mangrove swamp the 28 km² small "Thale Noi". The most striking feature is the long 75 km long spit which separates the lake from the sea. Unlike most spits, it is probably formed when originally existing islands became interconnected by the silting from the lake precursor.

Ramsar Wetlands

The Phru Khuan Khi Sian wetlands at the Thale Noi lake are protected as a Ramsar wetland since 1998. It is part of the larger Thale Noi Non-Hunting Area, created in 1975 [ [http://www.onep.go.th/wetlandsthai/Eng/data%20ramsar/Talay%20Noi.pdf Wetlands in Thale Noi Wildlife Non-Hunting Area (with a fine map and picture)] ] .

Kuan Ki Sian of the Thale Noi Non-Hunting Area is located at 07º50’N 100º08’E. in a Non-hunting Area. Located just north of the very large Thale Luang (Lake Songkhla) in the south of the country, it is one of the few surviving intact freshwater wetland ecosystems in Thailand. Among the specific wetland types found here are lake, marsh, Melaleuca (also termed "paperbark") swamp forest, paddy fields, and swamp grasslands.

"Kuans" are islands free of water for most of the year located in the Melaleuca swamp forest. Kuan Ki Sian is a knoll at 0-2 meters above mean sea level within the Thale Noi area. The Thale Noi area is home to more than 5,000 families, almost all of which rely on some resource extraction or other land use within the area. Activities include fishing, cattle grazing, cultivation, mat-making and tourism. The site is visited by more than 200,000 foreign and local visitors annually.

A small population of Irrawaddy Dolphins is found in the lake, however threatened to extinction by the overfishing and pollution of the lake. The IUCN Red List shows several populations, including those in the Mahakam River and Malampaya Sound, as critically endangered.IUCN2006|assessors=Cetacean Specialist Group|year=1996|id=15419|title=Orcaella brevirostris|downloaded=10 March 2007] .
