Fishing at Diamond Lake, Cochrane District, Ontario

• Overview

  Set in Cochrane District, Diamond Lake is an Ontario water. It sits at 232 metres above sea level. Roughly 15 hectares: a morning covers one end, an afternoon the other. The edge runs 1.8 km or so, easy to work in an afternoon. It lies lower than most water we list in Ontario. Nearest town is Hearst, 56 km off. After that come Hornepayne at 70 km and Manitouwadge at 128 km. The nearest boundary is a fair way off.

• Where to Fish on Diamond Lake

  No published figure covers depth, so learn it as you fish. 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. County-wide records name northern pike, yellow perch, white sucker and Iowa darter. The county list is broader than any single water. Treat Diamond Lake as a water to read rather than to cover.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 16°C, while January sits near -19°C. Long winters and short summers set the pattern. Firm cover through the cold months, then open water from early May. From about early May to around mid November, expect open water on the long-run figures. Late spring and early autumn carry the year between them. Expect Diamond Lake to follow that timing.

• Tackle & Baits

  We have no record of the rules that apply on this bank. It formed naturally, so levels move with rainfall rather than with a gate. Public mapping records no formal access here, so plan for a walk and soft ground. A small crankbait along the drop and a worm in the thick stuff cover the bass. Look for a notice board at the entrance. Rules for boats are stricter than rules for the bank in many places. Auden Lake sits 5.8 km off and takes the overflow. Confirm before you fish Diamond Lake.
