Okay mfick, what say we work through the process so that others can learn it and help their exploring.
1. First off, and i cannot stress this enough, buy a DeLorme Michigan Atlas and Gazetteer
which you can find possibly in your local bookstores, if not once in Michigan or online. It will do wonders in helping you find little out of the way places, roads and even 2-tracks to get to them throughout federal and state land.
2. Check out this DNR webpage: DNR - Inland Trout and Salmon Regulations and Maps
which will not only direct you to rules and regulations, yet help you find general maps of Michigan Designated Trout Streams
3. Using the above page and centering on Grayling as our starting point, we then work around map region 30 which gives us this:
Grayling, region 30: http://www.michigan.gov/documents/dnr/30_416022_7.pdf
Region 31, E.: http://www.michigan.gov/documents/dnr/31_416023_7.pdf
Region 34, S.S.E.: http://www.michigan.gov/documents/dnr/34_416029_7.pdf
Region 33, S.S.W.: http://www.michigan.gov/documents/dnr/33_416026_7.pdf
Region 29, W.: http://www.michigan.gov/documents/dnr/29_416020_7.pdf
...and I'll save you the trouble in that Region 27 due N. is sparse enough not to consider for a brief trip (though might hold some surprises I don't know about not shown on the map).
The color codes (found in the fishing guide) translate as follows based mostly upon seasons, limits, and gear allowed:
Water in general not considered a "designated" trout stream under specific regulations yet fall under general regulations and open year round.
Are season restricted yet open to bait, lures, fly.
Are season restricted, size restricted, and artificial lure and/or fly restricted.
in the guide): Open all year yet size and lure and/or fly restricted.
Open all year, size and bait/lure/fly restricted.
Confused yet?.....It gets worse in that you need to then in the guide find each body of water based on county and it will give you the specific restrictions......Also know that limit (catch and keep) changes and so on are noted.
However, at this point, lets simply use the maps to narrow down where to fish understanding that those restricted areas mean prime trout waters, some "Blue Ribbon"
Trout streams: Michigan's Blue Ribbon Trout Streams
That said, easy access is probably more abundant, but due to that so is the traffic and pressure.....I myself will 95% of the time due to that hit those green marked rivers off of those quality waters.
Here is where the Delorme Atlas comes in.....
Selecting smaller streams off of prime waters I can then look at the atlas and see what roads parallel the rivers. Very often even USFS fire trails, and roads for logging are marked on those maps, so it makes it easy to figure out spots close to the river to get in at.
With that in mind, look at:
1. The Blue Ribbon Trout Stream map.
2. Consider the (going from due W. C.W. 180deg.) Manistee, Boardman, Jordan, Boyne, Sturgeon, Pigeon and AuSable systems.
3. Look at the trout reg maps listed above, and ideally print them off to have in hand when there.
4. At that point pick a couple spots that just call out to you (and it is GOOD that using the above maps it is still vague). I'd suggest a green colored branch off of one of those rivers, yet you might decide on one of the better bits of it.
5. At that point I can look in my books and tell you how to get there, where you might have easy access, and some even have VERY detailed descriptions of the waters and fish to be found.....Some right down to the hole or bend, others just give you a hint to explore yourself knowing what they're connected to.
I know you'd just kind of like to have me say "Go here, cast this fly in to this hole and post pictures".
Yet frankly this is the same process I go through for myself every time I fish new water, and having not personally fished those waters myself, you might be surprised how well it works.
Literally by using the above process I have flown over a thousand miles to a place i have never been, get in a Jeep and drive ultimately going down 2-tracks that are mapped, make a short walk from the descriptions found in my research, pick a spot, toss in a fly and wham, fish on......and it's not failed me yet.
I refuse to simply cast every square inch of water on a river....I'm not Bass fishing.
