Michigan Spring Steelhead Run Board
Where is the water warming toward spring steelhead conditions? Compare real USGS water temperatures, discharge and seven-day flow trends across six rivers. These are river-condition signals, not live fish counts.

What triggers the spring steelhead run?
Warming water is the key signal. Steelhead can be in rivers long before spring, but warming from the 30s into the 40s can coincide with greater migration activity. The 38–52°F band is a broad cue, not an exact onset or spawning threshold. A single reading cannot prove fish are moving.
Watch changing flow. Rain or snowmelt can create river pulses that coincide with movement. This board uses the same seven-day USGS flow trend as the fall tracker. Rising discharge can also mean dangerous wading or muddy conditions; the status is not a safety rating.
Which Michigan river should I watch?
Muskegon below Croton and Big Manistee below Tippy offer USGS temperatures and flows for tailwater planning. The Pere Marquette and White have no temperature reading at these gauges and cannot be temperature-ranked. The Little Manistee has weir-related considerations; check current restrictions. Au Sable below Foote tracks a Lake Huron tributary.
When is spring steelhead season in Michigan?
March and April are the broad seasonal window, but weather and river conditions can shift activity earlier or later. The board remains useful outside those months without falsely calling a spring run. A temperature match during March–April is a starting point for research, not proof of a productive fishing trip.
Does this show where steelhead are spawning?
No. USGS gauges measure water, not fish numbers, spawning locations or catches. Avoid disturbing redds and check Michigan DNR regulations, special closures, stream access and safety conditions before you fish.
For fall fish, use the salmon and steelhead run board. For all three seasons, see the steelhead guide.
