Thale Noi Non-Hunting Area is part of the greater Songkhla Lake Basin, the largest lagoon lake in Thailand, covering an area of over 8,000 km² (3,100 sq mi) in its entirety.
The lake joins with Thale Luang, a 473 km² (183 sq mi) basin, via 3 channels – Khlong Naang Riam, Khlong Ban Klang and Khlong Yuan, however sluice gates were installed in 1956 by the Royal Irrigation Department to prevent salt water intrusion  to create freshwater conditions conducive to rice production  (see Environmental Threats).
Thale Luang adjoins Thale Sap (360 km² or 140 sq mi) which connects to the southernmost lake, Thale Sap Songkhla (182 km² or 70 sq mi) that opens into the Gulf of Thailand  through a 380 m wide strait.
Approximately 94% (422 km² or 163 sq mi) of the reserve is terrestrial and 6% (28 km² or 11 sq mi) is aquatic.
Thale Noi lake is approximately 5 km wide and 6 km long with an average depth of 1.2 m, however water levels fluctuate significantly with changing seasonal conditions, dropping to around 80 cm in dry season and increasing to a depth of 3 m in some areas during the wet season.

Thale Noi Non-Hunting Area is a biologically diverse wetland with multiple habitat types supporting a vast array of flora and fauna species.
Dense Melaleuca forests dominate the north and south  with extensive rice paddy fields to the east and remaining areas combine swamp marsh, grassland and sedge beds, with only a relatively small area of open water.
