What is working right now

Folsom Lake was slow in early December 2025. Jerry Lampkin ran the North Fork, the dam, and the South Fork and marked fish deep, but they would not commit to trolled lures. The water was a clean, calm 63 degrees. The day ended with a rainbow trout and a bass hitting as the lines came up. A tough day, but not a skunk.
