Trout are found in many Pennsylvania waters. In addition, Lake Trout are found in Lake Erie, Raystown Lake and the East Branch Clarion River Dam. You can pursue trout in tiny mountain brooks, famous limestone streams, large rivers like the Upper and West Branch of the Delaware and the Youghiogheny River and the tributaries and ocean-like waters of Lake Erie. With nearly 16,000 miles (and counting) of wild trout streams, nearly 5,000 miles of stocked trout streams and over 125 stocked trout lakes, PA has something to offer every trout angler.

MassWildlife will be stocking brook, brown, rainbow, and tiger trout this spring and fall. This year’s fish are bigger and better than ever. While the quantity of stocked trout (measured in total pounds) has remained about the same for the last decade, MassWildlife has been steadily producing larger trout by adjusting hatchery growing techniques. Just ten years ago, less than 60% of stocked trout were over 12 inches—now, over 80% measure over a foot!

Maine is the only state with extensive intact populations of wild, self-reproducing brook trout in lakes and ponds, including some lakes over 5,000 acres in size. Maine's lake and pond brook trout resources are the jewel of the eastern range: lake populations are intact in 185 subwatersheds (18% of the historical range), in comparison to only six intact subwatersheds among the 16 other states." Furthermore, Maine is the last true stronghold for stream dwelling populations of wild brook trout, supporting more than twice the number of intact subwatersheds as the other 16 states in the eastern range combined.

Trout fishing in the "Granite State" is all about variety. Whether your passion is a multi-colored brook trout, a leaping rainbow or the determined fight of a brown, there's a trout pond or stream within reasonable driving distance for most New Hampshire anglers. Trout are prized by anglers because they can be a challenge to catch, and fishing for them is one of the traditional rites of spring.
