Be sure to obtain a summary book of laws and regulations with your license. Refer to the boundary/border waters section and follow the regulations for size, creel limit, and open season. An angler may use a maximum of two lines. Trout stamps are required with a PA license to take, kill, or possess any trout. Fishing licenses may be purchased from local sporting goods stores or other state license issuing agents. Watch for Fish-For-Free Days during National Fishing Week in June of each year. Along the Upper Delaware, a license is not required on these days; all other regulations still apply, however.
