• Where to Fish on Duncan Lake

  Nothing in our records gives a depth for this one. Read the surface for the wind lane, then fish the edge of it. The shallow end warms first and pulls fish in ahead of the rest. Survey and observation records for Lake County include rainbow trout, sockeye salmon, smallmouth bass, yellow perch and largemouth bass. Protected fish appear in the records for this area, so treat the list as information, not an invitation. At Duncan Lake the first feature you find is worth twenty minutes.

• Seasonal Patterns

  Averages here run 58°F at the top of summer and 20°F at the bottom of winter. A solid cap is the normal state through winter. Ice fishing carries the winter, and the water opens about late April. On average, late April opens the water and mid November closes it again. Right after break-up, and again as the nights sharpen, is when to go. Duncan Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Public data does not answer the access question here. Nothing is mapped in the way of a ramp or car park within a short radius. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Sort the permit out before you load the car. Barbless rules turn up on managed water more often than not. Ashley Lakes at 1.3 miles is the sensible second choice. Check the position on Duncan Lake before loading the car.
