Patterson Creek is a small body of water in the middle of Ottawa, Canada. The creek was originally a small stream flowing east through a swampy area to the Rideau River. The construction of the Rideau Canal blocked the creek causing it to become much larger in size. The Creek originally ran from near Lyon Street all the way to the canal. The creek was named after George Patterson, an early settler who owned the lot where the creek emptied into the canal. In the 1890s work began on landscaping the area. The western portion of the creek disappeared, replaced by Central Park in one of the first projects of the Ottawa Improvement Commission.
