The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Muddler Minnow on the bob and Perch Fry on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Daddy Longlegs may strengthen through the middle of the day as conditions warm.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
