Davenport Creek flows into the west end of Gladys Lake, north of Surprise Lake, approximately 50 kilometres northeast of the community of Atlin.

The creek is located just north of the Late Cretaceous, primarily granitic Surprise Lake batholith (Surprise Lake Plutonic Suite). The northern contact of the batholith with limestones, cherts and argillites of the Mississippian to Triassic Kedahda Formation of the Cache Creek Complex is at the headwaters of the creek. The creek flows north, is about 6 kilometres long, and has no exposed bedrock around it.

Placer operations have taken place near the bottom of the creek where it enters Gladys Lake. No work was recorded although coarse gold was reported during prospecting, shafting and tunnelling from 1910 to 1915 and 1920 to 1921. Around 155 grams of gold were recovered from the creek between 1916 and 1920.

Bulletin 28 records production from a period of 1916 to 1920 but, it most likely is from 1911 to 1915.
