Has anyone ever heard of coaster brook trout? They are brook trout that live on the northern coast of Lake Superior and live right up in the shallows in about 18" of water. I'm interested if anyone knows anything about them. Coaster brook trout are at risk because of stocked brown and rainbow populations in their waters. They thrived up until the mid 1800's when a large fishery ws establishedd for them and by the late 1800's they were almost extinct. They then came back to a healthy population by the mid 1900's but then gradualy decreased due to other competing trout species. Any information??

Yes I have heard of Coaster Brook trout. Very unique population for sure. You've have hit the majority of the high points. I was under the assumption that they ran into rivers and creeks to spawn and lived in the lake and grew large there, much like Great Lakes steelhead.

There are similar "salters" or sea-run brook trout in coastal waters in Maine (and presumably further up the Atlantic Coast). Very unique populations for sure.

They do run streams to spawn. But apparantly they grow to irregular sizes and lurk in the shallows of the lake rather than the deep year round.

This provides a pretty good overview:
