Conditions

Between seasons, the South Fork is fishing selectively, and you'll need technical presentations to connect with fish. Blue Winged Olives and Mahogany mayflies are active, along with terrestrials like ants, beetles, and hoppers. Water clarity improves as you move downstream from Palisades Dam. As of September 11, flows were stable near Lorenzo.
