[citation needed] Green Lake also contains a National Fish Hatchery, which is a part of the USFWS Atlantic salmon restoration and recovery program for Gulf of Maine rivers.

The largest togue ever successfully caught and measured occurred in 2017 during the Hancock County Ice Fishing Derby, weighing in at 15.29 pounds.

In the Summer of 2002, three locals were enjoying some golden hour trolling when something bit the line of one of the fishing poles that was so large, it started pulling the boat backwards.

When the local fishermen got the pole out of its hold, the entire thing was quickly ripped out of their hands and disappeared in to the depths of the lake.

Although these are the first two reported cases of a "large fish", the stories quickly made their way through the locals, with many more strange occurrences being added, until one year when at the annual Pancake Breakfast when a mysterious man no one had seen before or since said, "Sounds like Guffer McKenzie has come out of hiding to start messing around again."
