Big stonefly nymphs are beginning to move on the lower river. We have reports from folks seeing a few nymphs here and there from Warm River to top of Chester backwaters. That bodes well for this weekend if one enjoys pithcing big stonefly nymphs. Use sink tip lines, and try your favorite giant stonefly nymph pattern. Don’t forget that caddis life cycle patterns could also be effective, especially later in the day. Although likely that it will be crowded, don’t overlook Box Canyon. Both caddis life cycle and big stonefly nymphs could be effective here.
