Latest fishing report
Fall outlook: DWR's community fishery trout stocking typically resumes in late September, once the water is cooler and its quality, measured by pH and dissolved oxygen, has improved. It generally runs through October and ends in late November, and trout fishing turns good to great in the cooler fall months. In September the much warmer surface water pushes trout toward the bottom. Later, as the surface cools, the temperature evens out through the water, and the trout then feed actively at every depth, including the surface, to bulk up ahead of winter. Inline spinners, casting spoons, minnow-imitating baits, marabou, hair and tube jigs, dry flies, nymphs fished beneath an indicator, dry-dropper rigs, woolly buggers, nightcrawlers and trout dough bait can all be very effective.
