The Little Tuya River is a tributary of the Tuya River in northwest part of the province of British Columbia, Canada.[1][7] It flows generally south and east about 71 km (44 mi)[5] to join the Tuya River near Cariboo Meadows.[8] The Little Tuya River's watershed covers 569 km2 (220 sq mi),[6] and its mean annual discharge is an estimated 6.69 m3/s (236 cu ft/s).[6]

The mouth of the Little Tuya River is located about 45 km (28 mi) northeast of Telegraph Creek, British Columbia, about 48 km (30 mi) west-southwest of Dease Lake, British Columbia, and about 215 km (134 mi) east of Juneau, Alaska. The river's watershed's land cover is classified as 37.8% shrubland, 28.8% conifer forest, 14.6% mixed forest, 9.2% barren, and small amounts of other cover.[6]

The Little Tuya River was named in association with the Tuya RIver. A tuya is a geologic term for a flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet. The geologic term comes from Tuya Butte, which was named in association with Tuya Lake.[9] The term may come from the Tahltan language.[10]

The Little Tuya River is in the traditional territory of the Tahltan First Nation, of the Tahltan people.[11][12]
