Re: Hello! new to forum...
Welcome to the forum. We are glad you found us and look forward to your participation.
Obviously if your water has a heavy hatch on the surface you will probably catch more on the surface. Other times you may do better sub-surface. Your water has a lot to do with it. In the high Serra's there are many small streams and I always fished with drys all season long. Never did see a hatch on the water but the dry flies worked. In this case it may have been a combination of thin water and a very short season.
