The Port Hope fish migrations are among Mother Nature's most impressive wonders. Thousands of salmon and trout swim upstream and jump the fish ladder to migrate to their spawning grounds.

Thousands of fish swim against the current to head home

People come every weekend from mid-August to early October to watch the 5,000 to 10,000 chinook and silvery coho salmon swim from Lake Ontario up the Ganaraska River that runs through Port Hope on their way to their home spawning grounds. And as many as 18,000 trout a year make the same journey from late March until early May, or through October until mid-December. Fish fact: The Ganaraska River is one of the healthiest rivers in Ontario, populated almost entirely with wild naturally-reproducing fish.

You can see the pooling stations for fish in the shallow water at various points along the river in town. The best viewing spots are along the river trails downtown and the Ganaraska Fishway, managed by the Ministry of Natural Resources and Forestry (MNRF). It's more commonly known as the Fish Ladder at Corbett's Dam (the dam is managed by the Ganaraska Region Conservation Authority where an underwater monitoring system lets you watch the fish! It records the number of fish that pass through to travel to their spawning grounds, as well as the species, size and health.
