Weston residents wondering what has happened to Humber River salmon this fall will be pleased to know that their arrival is imminent. According to Toronto and Region Conservation Authority (TRCA) workers, the problem has been the antics of downstream wildlife and a recent dry spell.
A big obstacle to migrating fish is the 3 metre tall weir/dam in Raymore Park. A few years ago, a denil fishway (aka fish ladder) was built thus extending the migratory range of several species. Unfortunately, beavers stuff the fishway with wooden debris in the hopes of creating a dam. On Friday, two workers were clearing the way for the salmon and told WestonWeb that as soon as water levels rise, these large Lake Ontario fish will be able to access the ladder. From there they will swim upstream to their birthplace, spawn and return to the lake – assuming they can run the gauntlet of people out to get them.
In spite of their impressive size, salmon will be seen along the Humber as far as Bolton and Palgrave. For its part, the TRCA is studying the removal of obstacles to fish migration along the Humber and the weir in Raymore Park is definitely one of them. Probably a good thing as the beavers are relentless in their efforts to block the fish ladder.
