Even the though Brookies spawned in the fall and the Rainbows spawned in the spring and there was no competition for prime spawning areas. A Steelhead is a completely different specie that a standard Rainbow Trout because of it's migratory nature. A Steelhead is a strictly anadromous fish , meaning it returns to the river where it was born, it's ancestry can be traced to both Salmon and Rainbow Trout. By migrating to huge bodies of water like the Great Lakes, these fish have a much richer forage base to feed on, and can attain size never achieved by staying in the same river all year.
The point I'm trying to make here is; the State never knew exactly which specie they received back in the late 's. The first truly documented specie of Steelhead was in and In 15, of them when into the Muskegon River and some were planted in Lake Superior, this could have contributed to the early controversies between Steelhead vs.
Although, by then there were resident populations in the Little Manistee and other rivers. Our fish are a result of forced hybridization or contamination between several different groups. By the early 's weirs were set up to collect eggs off the mouths of several different rivers and the remains of one even to this day, can be seen at the mouth of the Little Manistee River, left over from bygone era.
Steelhead have been called Steelies, Ironheads, 'Bows and numerous other things. It is said that because of the blue tinge of steel, it resembles the fresh run fish entering a stream they became known as Steelhead. One thing here nobody will disagree with, they're one of the strikingly attractive fish you'll ever gaze upon. We now have a trilateral fishery for Steelhead in Michigan today. The first one is the outstanding "World Class" river fishery we have from January thru April.
The fish, until February for the most part are pre-spawning fish, waiting for 38 degrees of water temperature to move into the faster areas of water and gravel beds or redds for reproductive purposes.
Look for these fish that are in a holding pattern, to be in the slower or slack currents of the river or stream you plan on fishing. Once on the gravel, they'll hit just about anything near their nest. However, the winter-run species have limited access to spawn timing before they are ripe for reproduction with eggs and sperm. On the other hand, summer-run fishes start venturing into the freshwater at the start of April. They start entering in bulk as the warmer months start in and are done before November starts approaching.
Apart from this, you also need to keep in mind the fact that the sexual maturity of your summer fishes tends to vary substantially from the winter counterparts. Further, mild weather along with comfortable temperature within the water body enhances the metabolism of the Summer Steelhead while their aggression tends to be too high. This is why the summer-run fishes are sought after by most angling enthusiasts.
Regardless of the differences amid their migration timings, both summer-run and winter-run fishes spawn early in the summer and spring. If you have fully understood the point explained above, you will surely relate when we say that timing is the key to it all. Steelhead can be hard to identify.

Non-Native Fish Two dorsal fins including one adipose fin, mouth and gums are light, small spots along rays on entire tail, rays in anal fin. Steelhead is a name given to migratory rainbow trout that are born in rivers but spend most of their lives in the ocean or the Great Lakes.
Steelhead are known fighters, making them a very popular species for sport fishing. They are pursued by Great Lakes trollers, pier anglers and surf anglers. They also provide an exciting river fishery in many Great Lakes tributary streams.
Steelhead make great table fare and their fillets can be smoked, grilled, broiled or fried. This is an unbeatable combination that makes them one of Michigan's most popular sport fish! The range of temperatures and abundant food at thermal fronts can be clues to help you find steelhead and other fish in the Salmonidae family. During the winter-summer transition April to mid-June , temperature is an important thing to consider when looking for fish.
Because at that time, a body of water with frozen or near-freezing surface water temperatures and underlying warmer waters, changes to a body of water with warmer surface water temperatures and cooler bottom waters. In the spring, a thermal bar 4 degrees C is formed when surface water temperatures rise and colder offshore waters mix with warmer nearshore waters. Next, the spring thermocline forms degrees C , typically between the shore and the thermal bar. The spring thermocline is characterized by closely spaced isotherms from 43 — 46 degrees F degrees C.
In May and June, the thermal bar and spring thermocline move offshore and thermal breaks greater than 9 degrees C form. As temperatures warm, all three of these thermal fronts continue to move offshore. Later in the season, fishing is influenced by thermal fronts and water temperatures associated with upwelling:Figure 3. Upwelling occurs when strong winds push away surface waters allowing deeper, colder waters to rise to the surface.
Upwelling occurs near the shore caused by strong winds from the east, northeast or northwest — any wind that moves the nearshore water offshore or any prolonged wind that causes a strong north to south current. The bathymetry near Big Sable Point contributes to a cold-water upwelling associated with strong winds from the east, northeast or northwest.
Deep waters nearshore at Big Sable Point are key. As warm surface waters are pushed away by the wind, deep cold waters near shore upwell to the surface see Big Sable Point bathymetry.
Under these conditions, warm waters will be found as deep as feet or more typical depth of warm water is feet. Temperature is less of a fish-catching factor as summer becomes fall, because fish enter river mouths and many move upstream.

Prey is often abundant at thermal fronts and fish in the family Salmonidae, particularly steelhead in eastern Lake Michigan, seem to be attracted to spring thermal fronts to feed on insects that originate on land terrestrial rather than the water.
We know this because researchers found that terrestrial insects were abundant in steelhead stomachs in the spring. Accumulation of these insects is thought to be related to the eastern central Lake Michigan shoreline. Insects along steep, sandy cliffs are caught in rising air currents, and as the air cools over colder lake waters, they are deposited into the lake, essentially raining down food for steelhead and other fish.
Knowing this, how can we apply it to find fish? Commercial, subsistence and recreational fishermen use surface water temperatures and visual clues to find thermal fronts. In the spring, fishing is best at thermal bars nearshore. Look for tight contour lines following the shoreline with a degree temperature change over the course of the lines. Fishing is best in the area outside of the series of contour lines. Thermal bars may be present until mid-June or possibly early July.
When waters reach 60 degrees F, thermal bars no longer form.
