Designated Trout Streams of the
North Shore of Lake Superior
(see also: Duluth Area | South Shore trout streams)
The Reports section has more information indexed by streams.
This is only a partial list of the trout streams along the North Shore of Lake
Superior but includes streams that are intensively monitored for flow with seasonal and event-based sampling by MPCA,
plus other trout streams that are on the federal/State
Impaired Waters List.
Why these streams?
These streams are attractive to trout because they provide
all of the elements of good trout habitat including:
Cool water temperature (around 60° F, depending
on the species). Water temperature is effected by the
amount of paved areas (impervious surfaces)
within watersheds. These surfaces soak up the sun's rays, and heat the rainfall that runs into
the local streams. When water temperature gets too warm, it can't hold enough oxygen for fish survival.
Coarse stream bed sediments provide hiding places
for the insects and other invertebrates that fish eat, and are a place for fish to spawn. Silt runoff from
construction and other human activities can clog up these spaces.
These are only a couple of the things necessary for good trout habitat.
