The lower river is the best fishing location. Green drakes are out in the afternoon, then the gray drakes take over in the evening. PMDs and caddis are abundant at these times, too. Use your favorite patterns for these. Expect much boat traffic on the lower river until the South Fork “high tide” diminishes. On the upper river the PMD emergence is the big event and there are plenty of caddis in many kinds. Green drakes have been sparse to non-existent.
