Today's AI read

Warm-water pattern for Largemouth bass / Channel catfish

66 confidence

Warm water pushes the plan toward oxygen, shade, depth changes, and low light. Wind is not the main constraint, so timing and presentation can drive the plan. With a weak solunar score, favor stable weather windows.
