Blue Olives have been hatching on the warm days, expect them in the afternoon hours. No word on the March Browns but they should hatching anytime, and I would have some with me just in case. Nymphing is the name of the game for the majority of the day, rubberlegs and beadhead nymphs. Many people are having great success below Chester Dam, down to Del-Rio Bridge. Warm River to Ashton is fishing as well. However I have not heard if the self ice has melted at the Ashton boat ramp yet. A few weeks ago it was about 4 feet high. I would call ahead before you launch your boat.
