I apologize if you have already done the search, but I find searching for "[stream name] hatch chart" usually turns up some good results for me. If the stream isn't available I look for something more popular that is close. I had some good days with Blue Wing Olives in march, but I'm not in the same part of the state. In April I will look forward to Hendrickson's, March Browns, Grannoms etc... My dad always says "show me a fisherman and I'll so you and optimist." Maybe I'm falling into that category right now. I think stone flies are coming off in some places now too. I guess it depends where you are. Best of luck!
