• Seasonal Patterns

  Climate normals give 72°F for July and 23°F for January. Expect a real winter and a strong spring after it. Count the season from break-up, usually late March. On the long-run averages the water opens up around late March and starts locking again about late December. From the thaw to midsummer the fishing improves week by week. At Diamond Lake the season follows that pattern closely.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. It formed naturally, so levels move with rainfall rather than with a gate. Diamond Lake Public Boat Launch gives a made launch, half a mile off. The closest car park is half a mile away, so pack accordingly. Where the road in crosses private land, ask first. Some stretches are reserved and marked as such on the ground. Should this one be busy, Stone Lake is 2 miles off. Nothing on Diamond Lake should be assumed from this page alone.
