Most of the creek and its sources are buried underground in storm sewers until they emerge into Avoca Ravine in the Deer Park neighbourhood and continue their way to the Don River.

[5] The modern storm sewer main located near the confluence of the two former streams at Bathurst Heights and near Briar Hill Avenue is a major source of water for Yellow Creek.

[8][9] It surfaces at the southern end of Mount Pleasant Cemetery, flows in a southeasterly course to the Park Drive Reservation Ravine,[10] and then towards the east until it empties into the Don River.

[10][13][14] In 2019, The Toronto and Region Conservation Authority identified Yellow Creek as a location which has become a public health concern due to erosion damaging pedestrian paths.

Exposed rock retaining walls were removed and replaced with a more gently sloped creek bed which will be less prone to collapse due to erosion.
