St. Croix River Professional Review and Guide
"This wide river has a moderate flow, and is best fished from a small motorboat or canoe. The St. Croix is a boundary river with Canada and special boundary water regulations are in effect.
These regulations are complex and vary considerably from Maine’s General Law. Bag limits, open season dates, minimum length limits, equipment, legal hours, and bait types are all affected, so study the Open Water Fishing Regulations booklet carefully before fishing in this area. Campgrounds are located in Alexander, Calais, and Perry. Motels are available in Calais. Key Species: smallmouth bass, pickerel."
