Mississippi River

The Mississippi River flows into Upper Mazinaw Lake at its northern end, forming part of a scenic inland watershed that winds through Eastern Ontario’s cottage country. The river passes through a series of lakes, wetlands, and forested Canadian Shield landscapes before reaching Mazinaw, where it helps sustain the lake’s water levels and cold-water ecosystem.

Along its course, the river runs near small communities such as Northbrook and Cloyne, both of which serve as gateways to nearby recreation areas and services. The broader region is closely tied to Bon Echo Provincial Park, which is one of the area’s main attractions, known for hiking trails, canoe routes, and the iconic Mazinaw Rock.

Fishing along this stretch of the river and into Upper Mazinaw Lake is generally strong, with species such as smallmouth bass, northern pike, and panfish common in the warmer, shallower waters, while deeper areas of Mazinaw support lake trout. The mix of river and lake environments makes it appealing for both casual anglers and those targeting multiple species in a single trip.
