I wish I knew. Every time I thought I had them figured out...they quit! Would catch one here and one there. Then it dawned on me....that was my pattern for the day... Run and Gun. Don't stay in one place too long cause they just ain't going to bite. I can say that without doubt the best color for me today was a blue/treuse jig by B. Garland. The bite was very light to "hey, there's a fish on my line". Brought home a dozen nice ones with the big fish of the day going right at 15 inches. Lake Murvaul.
