The colour is this river's run stage today, read off MDNR
run-timing guidance. Where along the corridor the fish are is not
modelled here — only the sixteen rivers the staging estimator covers
carry that.
Drawn 30 September 2026, north up, and it is a map of the river rather
than of the lake it runs from.
Great Lakes tributary rules are their own rules, and they are not the inland trout regulations: seasons, gear and possession on run water differ by river and often by reach. MDNR's own guide is the regulation on the Two Hearted River and this page is not. Lake-run brook trout carries a restriction of its own on this water, and the notes below say which. 5 run species are recorded on this corridor, and the season on each is the state's rather than the window on this site's calendar — a window is when the fish move and a season is when you may fish for them.

Where the rules are
Great Lakes tributary regulations are their own rules — seasons, gear and possession on run
water differ from the inland trout regulations, and they differ by river and often by reach.
Michigan's regulation summary on this site is here, and
MDNR's own guide is the regulation.
Species carrying their own rules
Lake-run brook trout
Coasters are a managed restoration fishery under special catch-and-release regulations on much of this shore, and the rules differ river by river. Read the state guide for the water you are on.
The run species and their windows
A window is when the fish move and a season is when you may fish for them. These are the
windows; the seasons are in the state's guide.
