Freshwater Fishing.

Twelve Mile Creek and its headwater tributaries hold brown trout and rainbow trout, with public access at Short Hills Provincial Park (where Ontario Parks lists brown and rainbow trout among the park's permitted angling species) and at St. John's Conservation Area, an NPCA-listed seasonal trout fishing hot spot in the same valley.

Lake Gibson at Mel Swart Lake Gibson Conservation Park adds an urban warmwater shoreline option.

Freshwater Fishing in Thorold
01 — What to know

The brief.

Short Hills Provincial Park brown and rainbow trout fishing requires a valid Ontario fishing license; the park is a non-operating day-use site (sunrise to 10 PM, no entrance fees, no overnight facilities). St.

John's Conservation Area is described by NPCA as a hot spot for seasonal trout fishing in the Twelve Mile Creek valley; access is free, year-round, sunrise to sunset. Lake Gibson is a man-made reservoir formed by flooding Beaverdams Creek with water from Lake Erie; the boardwalk in Mel Swart Lake Gibson Conservation Park is the public shoreline access point.

Anglers should consult the current Ontario Fishing Regulations Summary for season dates, possession limits, and any sanctuary-water restrictions in the Twelve Mile Creek system.
