The creek was originally a small stream flowing east through a swampy area to the Rideau River.
The construction created a small island in the creek that then housed the Cedar Lodge, but this structure was demolished in the 1930s.
The western portion of the creek disappeared, replaced by Central Park in one of the first projects of the Ottawa Improvement Commission.
Today Patterson Creek runs for two blocks from the canal to just west of O'Connor Street.
The creek is located in the northern part of the Glebe neighbourhood, just to the south of the Queensway and Centretown.
