Mountain Lake Fishing near Wiarton, Ontario

• Overview

  Mountain Lake sits in Grey County, out in Ontario. Height above sea level is 226 metres. At 2.46 sq km this is proper open water rather than a pond. Some 19 km of bank gives room to move when the wind turns. Few waters listed in Grey County are bigger. The closest town, Wiarton, is 8.3 km away. The big place round here is Barrie, 115 km distant. A county boundary sits nearby, which can matter for local access rules.

• Where to Fish on Mountain Lake

  Nothing we hold settles how deep this runs. Still water like this holds fish on the edges rather than out in the open. Bays and points beat straight shoreline every time on water like this. Species logged across Grey County include Chinook salmon, rainbow trout, brook trout and white sucker. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. On Mountain Lake a short move beats a long cast.

• Seasonal Patterns

  Long-term averages put July at about 19°C and January near -7°C. Winter puts a hard lid on this one. The lid usually sets by midwinter and gives way around mid April. Average temperatures cross freezing around mid April in spring and again near mid December in autumn. Just after the ice goes and just before it returns, the fishing lifts. Plan any trip to Mountain Lake around it.

• Tackle & Baits

  Access status is simply unknown for this water. It formed naturally, so levels move with rainfall rather than with a gate. Overnight stays are possible about 470 m out, where camping is mapped. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Parking space is the usual limit rather than the bank itself. Where tickets apply, they are sold in the nearest town rather than on the bank. Failing this one, try Scale Lake, 3.2 km away. Treat access at Mountain Lake as something to verify.
