Hatch dates and times are heavily dependent upon weather, stream temperature and stream location. The dates given are approximate and in some years, can vary greatly. Dates are based upon the average of many years of observation and fishing the limestone steams of Central Pennsylvania. 

For the most current hatch information and stream conditions, give Penns Creek Guides a call at (814) 364-9142.
