The Nottawasaga River offers unique fishing opportunities, particularly for rainbow trout (steelhead). This river is accessible year-round due to its catch-and-release zone, making it a popular destination for anglers. Fishing tournaments, such as the Georgian Triangle Salmon Slam, attract numerous participants and generate significant revenue for the local economy.

The health of the river is crucial for both the fishery and the local economy. The river boasts high water quality and excellent habitat conditions that support various fish species. Restoration efforts, including fixing bank erosion and improving fish habitats, are essential for sustaining the river’s ecosystem. The Nottawasaga River Restoration Program (NRRP) aims to restore 10 km of degraded stream habitat, enhancing water quality and fish habitats. These efforts also provide benefits for flood and erosion control.

The Nottawasaga River flows through significant environmental features such as the Niagara Escarpment and the Minesing Wetlands, making it a vital recreational resource and a critical source of clean water. The river supports sport fisheries, which are economically important for local municipalities. Native species like brook trout and river burbot, as well as species at risk such as lake sturgeon and northern brook lamprey, rely on the river’s healthy waterways.
