About this water

The Bighead at Meaford is a tidy, well-liked Georgian Bay steelhead river — clear limestone water with spring and fall lake-run rainbows and autumn chinook. It fishes well on the drop and gives a quieter option than the bigger systems, with classic riffle-and-pool nymphing water.

Under the surface

The Bighead reaches Georgian Bay at Meaford and is a well-regarded smaller steelhead river below the Escarpment, with spring and fall lake-run rainbows and autumn chinook. Clear limestone-influenced water of riffles and pools, it fishes nicely on the drop and offers a quieter alternative to the larger Georgian Bay systems.
