# Sixteen Mile Creek (Halton Region)

Sixteen Mile Creek is a river in Halton Region in the Greater Toronto Area of Ontario, Canada. It is in the Great Lakes Basin, and flows from the Niagara Escarpment through the towns of Milton and Oakville to Lake Ontario.
The creek is named for the distance from the river's mouth to the western end of Lake Ontario. It was previously known to the Mississauga Indians in their language as Ne-sauga y-onk or niizhozaagiwan ("having two outlets") and to the French as Rivière de Gravois ("gravelly river").
Like many creeks draining into Lake Ontario, Sixteen Mile Creek has cut a deep valley that is home to a broad range of wildlife, including whitetail deer, raccoons, foxes, opossum, and squirrels. The forest contains tree species typical of the Carolinian forest habitat, although since this is close to the northern limit of this zone, some are poorly represented. The total area of the drainage basin is 372 square kilometres (144 sq mi).
In Oakville, it also forms part of Glen Abbey Golf Course and is home to the Oakville Yacht Squadron.

## Fishing

Conservation Halton identifies Sixteen Mile Creek as an excellent fishing site in Oakville and Milton. The entire watershed provide numerous angling opportunities.
According to Conservation Halton the west branch provides excellent coldwater habitat for brook, brown and rainbow trout. During their spawning runs, both in spring and fall, chinook salmon can be seen in Sixteen Mile Creek. Stocked trout had been unsuccessfully introduced to the Mill Pond near downtown Milton. Although the pond does not provide suitable habitat to sustain trout populations it is a great location for fishing a number of panfish and carp. Both the middle and east branches provide opportunities for smallmouth bass fishing. In addition the lower reaches near Lake Ontario provide a migratory corridor for Lake Ontario fish. Oakville Harbour is a relaxing urban setting for angling trout and salmon before they make their spawning voyage upward Sixteen Mile Creek. The rocky banks of the Oakville Harbour provide excellent habitat for smallmouth bass.
