Read the surface for the wind lane, then fish the edge of it. Open biodiversity records for Watonwan County list common carp, walleye and black bullhead. The county list is broader than any single water. The shape of Irish Lake decides where the fish sit.

• Seasonal Patterns

  Expect July near 72°F and January near 13°F on the long-run figures. Winter puts a hard lid on this one. Hard cover is dependable here; it goes around early April. Climate averages put the opening at about early April and the closing near late November. The strong weeks are the first after break-up and the last before the freeze. The season on Irish Lake follows the weather closely.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. No dam controls it, and the level follows the season. Parking sits half a mile out, which makes for a walk with tackle. A small crankbait along the drop and a worm in the thick stuff cover the bass. A landowner's word beats anything printed elsewhere. Where parking is tight, arriving early solves most problems.
