Michigan Flyfishing trout photos from the Au Sable River 2005 & 2006. 


June 28th - Tom Olenczuk with a true trophy size brown trout (27" and 9lbs.) caught on a Hex dry fly.  This is why we sit out late at night on the Hex hatch!   Had another brown in the same size class break off about 15 minutes before we found this one.  Got a little lucky on the weather tonight.  Had major storms come through the area but rain stopped just before dark.  There was a very heavy hatch of Hex duns right before and after dark.   Look for heavy spinner falls the next couple of nights if we have dry warm weather.


June 21st - Mark Niedzwieski with a big brown caught during the Hex Hatch on the AuSable River.  The last few nights there have been no big heavy hatches but good Hex spinners right around dark.  At the current rate hatch could last for a while.  Should have good night time dry fly fishing at least until the 4th of July and probably longer if cool nights keep coming.


June 19th - Here is beautiful brown trout from the big waters of the Au Sable River above Mio caught on a Hex dry fly.   The last couple of nights the Hex have started to hatch in this section of river.  From the mouth of the South Branch all the way to Mio Pond has some excellent Hex water and is just getting going right now.   There are a number of good floats and walk in areas in this long section of river.   We have had a couple of cool nights and a little rain of late which has put the river is perfect conditions right now for night time dry fly fishing.  If your looking for day time fishing a good section is below Mio fishing crayfish/sculpin patterns or nymph fishing the riffles.


June 16th - Mike Sargent with a huge Au Sable River brown caught on a Hex dry fly.  Light spinner fall today but had a few huge trout up and rising.   Big trout were really out looking for bugs tonight.  We should have excellent night time dry fishing for next couple of weeks.


June 16th - Mike Sargent and Chris Poulus with a beautiful Au Sable River brown caught by Chris in the Big Waters below Mio.  We also had some very good dry fishing just before dark on good hatch of #16 blue winged olives.


June 15th - Here are a nice brown and rainbow trout caught streamer during the late afternoon.  This time of year, if its not to hot, afternoon and early evenings can be a very nice time to streamer crayfish and sculpins patterns on a long sink tip line.


June 13th - Here is a nice Au Sable River rainbow caught just before the mass of Hex spinners fell into river.  Just before dark there were good Isonychia duns and spinners and excellent dry fly fishing.  This nice rainbow took a #12 iso spinner on 5x tippet.   Once the big hex show up cut leader back to about 8' and 1x tippet.  Tonight there were very heavy Hex spinners just after dark.  We did find a couple of big trout rising but it was tough getting trout to take our flies with the mass numbers of bugs on the surface.  That is how the Hex hatch goes some nights!


June 11th - Tom Buhr getting the job done during the Hex hatch in the Big Waters of the AuSable River.  Tonight we had a heavy Hex spinner fall just before dark with a bunch of fish up and rising.  Seemed like it would be easy to catch them in the light but trout were very selective with all the bugs on the water.  Also had good a number of Isonychia and Brown Drakes hatching in the late evening.  Look for night time dry fly fishing to just keep getting better!


June 7th - Tom Buhr with a very nice Au Sable River rainbow trout.  Today we had excellent streamer fishing during the afternoon.  Crayfish patterns and natural sculpin patterns were very effective today.  We did not have tons of bugs this evening and dry fly fishing was a little slow.  Right at dark there were some isonychia, brown drake spinners, and march brown spinners.  It just seemed like there was not quite enough bugs to get the bigger trout up and rising.


June 6th - The last two nights Hex have started to hatch in the lower sections of the Big Waters of the Au Sable River below Mio Dam and below Alcona Dam.  These hatches are down in the very lower reaches of both of these sections of river.  When we get a couple more warm nights look for this hatch to really take off.  Best fishing is typically on the spinner falls.  Right now look for Isonychia hatch and spinner falls right around dark.  This bug is just getting going in the waters below Mio and has produce some good dry fly fishing the past two nights.  Still some Brown Drakes spinner around.



June 5th - Here are two big sources of food this time of year for the trout in the AuSable River - Isonychia nymph and crayfish.  Both of these come in huge numbers this time of year and can produce some very good day time fishing.  Isonychia nymphs live in fast riffles and are a swimming nymph.  Swinging and twitching these nymphs on a floating line down through the riffles will typically produce some good action.   Crayfish patterns can be fished on a sink tip and flies should be retrieved with quick strip jerk method.   Lots of different woolly buggers will work great for a crayfish pattern.


June 3rd - Here is Joe Stevens with a big Au Sable River brown trout caught on a brown drake dry fly.   There was a very nice brown drake spinner fall about a hour or so before dark.  Which made for some good dry fly fishing.  For a change the bugs came a little early tonight and it was still very light out.  Cool weather came in right at dark and end our bugs and rising trout.


June 2nd - Here is Tom Bushy with a very cool look rainbow trout from the AuSable River.  Had pretty good streamer action today.   Of late crayfish patterns have started to work very well.  During the day isonychia nymphs and crayfish colored buggers have been getting good numbers of trout in the deeper riffles.  There were lots of brown drake spinners just before dark but big storm came through and ended all dry fly fishing before it even started.


June 1st - Here is Barb De Roo with a beautiful huge Au Sable River brown trout.  Had a very nice float today and found a number of trout but nothing else the size of this one.  Best flies today were Stoneflies (dries) and Woolly Buggers.


May 28th - Here is a photo of a real brown drake spinner and my favorite spinner pattern.  The pattern was designed and tied by Jerry Regan and is the perfect pattern for fishing a brown drake spinner fall.  Look for some heavy spinner falls right at dark and after dark during the next week.  Last night was the first night I saw a good hatch of these big mayflies in the lower section of the Big Waters of the Au Sable River.  Typically after a few nights of hatches you will start having spinner falls.  The spinners are typically what get the big browns up and rising.


May 27th - David Frizzell with a beautiful AuSable River rainbow trout.  Had a very nice float on the river today.  The morning was a little bright and warm but had pretty good streamer fishing in waters below Mio.  With the warm weather best flies of the day were a tan Zoo Cougar and a JJ Special.  With bright conditions typically smaller streamers do work best.  Dry fly fishing was a little on the slow side this evening.  Did a short float from Parmalee Bridge to Whirlpool but did not find many bugs hatching and only a few small trout rising.   With the current conditions this should all change very soon.  The next week should be perfect for some of the bigger bugs to be hatching just before and after dark.


May 19th - Kris Walley with a huge Au Sable River brown trout.  The river is in great shape right now - water is up a bit with a slight stain and temps are in the middle 50's.  Today we had excellent streamer fishing and nice sulpur (size #16) hatch during late afternoon.  With the cloudy cool weather big trout were out looking for big flies.  Big Brown was caught on a 7" Finn Clip Rainbow.


May 19th - Here is another big trout from today's fishing.


May 19th - Here is photo of a big brown that smashed a 7" long rainbow pattern.  This time of year this can be one our best patterns for trophy browns.


May 2nd - Tom Olenczuk with a huge AuSable River brown caught on a Hendrickson dry fly in the Big Waters below Mio.  Had good dry fly fishing today.  Good hatches and spinner falls of Hendrickson all afternoon and evening.   Had a couple of huge trout chase streamers but best fishing was on dries.  Warm wet weather is forecasted for later this week which should be excellent for trout fishing.


May 2nd - Tom Bushy with a beautiful Au Sable River Brown caught on a Hendrickson dry fly.  Water levels are very low right now making for easy wading.



May 20th - Big browns were out hitting streamers today!  Here is Kris Walley with two huge Au Sable River browns - 26" and 27".  This is why we fish the big waters of the Au Sable below Mio.



June 29th - Hex hatch is not over yet in the Big Waters of the Au Sable!  The two big browns came about 15 minutes apart just after dark.  Hatch was not really heavy but enough to get some big trout up and feeding.  If you run into a night with no hex its a great time to throw a mouse pattern.


June 26th - Hex spinners over the the Au Sable River.  The dark cloud in the middle of the picture are all hex spinners getting ready to fall into river.  Hex hatch is going strong on the Au Sable River above Mio - McMasters Bridge to Mio Pond.  The last few nights very few Hex in the Big Waters below Mio.  It has been going for over two weeks down there and appears to be winding down.  Still could be a few more bugs - good time to start mouse fishing in that section.


June 25th - Big brown just got released after being caught on a Hex spinner.


June 23rd - Mark Niedzwiecki with a real nice AuSable River brown caught on a Hex spinner.  Super heavy bugs from Parmalee Bridge to Mio Pond.  There were even a few to many bugs tonight.  Hex hatch should keep going strong for the next week or so.  As the hatch moves on into late June look for the cooler sections of the Au Sable to fish the best.


June 19th - Here is John Demmer with a huge Au Sable River Rainbow.  John and his brother had excellent night time fishing with there Dad on a Fathers Day float trip.  All got big trout on the Hex!


June 16th - Mike Sargent with a real nice day time brown on the Au Sable River.  Trout was caught in the late afternoon nymph fishing a riffle with a Isonychia nymph.  We have had three nights earlier in the week with lots of Hex after dark.  The last two nights have been cool and with no Hex after dark.  On the cool nights there have been good hatches of Isonychias (maroon drakes) starting in the late evening - lots of trout have been up rising.  Look for peak of the Hex hatch in the big waters of the AuSable during the next warm up.  They are calling for it early next week!


June 8th - Finally a little rain this afternoon, river can use a lot more.  Had good trout fishing after the storm blew by.  Left photo is a big brown that was caught on large black leech pattern.  Right photo is our first trout of year taken on a Hex dry fly.  Lots of brown drakes today and the first night we saw a few big Hex duns.


June 5th - Lots of Brown Drakes on the Au Sable River tonight.  Perfect weather for night dry fly fishing - hot and muggy.  Look for Hex to start in about 10 days.


June 3rd - Tom Olenczuk with a nice big AuSable River rainbow trout.  The big trout hit a streamer in the late afternoon.  Streamer fishing has been a bit slow the past couple of days but as you can see there are still some very nice trout being caught .  Weather is calling for some rain this weekend which should help the fishing.


Aug. 4th - Had a really good hatch and spinner fall of this later species of Hex.  These bugs come out of Alcona Pond and lower couple miles of river upstream of the pond this time of year.  Look for this hatch to peak in the next week or so.  If the water is cool (below 70) look for some good trout to be up and feeding.  Also this bug will bring up some very nice smallmouth bass to the surface.  That was the case tonight - got a couple of real nice smallies just before dark feeding on Hex.  If high heat comes back best to stay out of the trout water and focus on the rising smallies down near the pond.


July 26th - More rain and cool weather today.  The Big Waters of the Au Sable are finally getting in good shape for trout fishing.  River is up a bit and water temps are in the upper 60's.  Good time to streamer fishing!  It won't be long now before white fly hatch starts in this water - typically right in the middle of August.


July 8th - A nice rainbow from the big waters of the Au Sable River.  Best fishing was right at dark on small olive dry flies - size #18.


July 7th - A boat full of Hex Duns.  Some of the cooler lakes and rivers in Northern Michigan still have some night time hatches of the big Hex Mayflies.


August 16th - Here is Nathan with a huge brown (26.5") from the Big Waters of the Au Sable River.  This beautiful brown was caught on a small prince nymph during the afternoon before White Fly hatch.  The last few nights White Flies have been a little on the light side but big trout can still be caught!  Prince nymphs and light colored hares ears are top producers right now during the day time hours.  In the evening soft hackles and white fly (ephrons) nymphs fished just over the surface have been very productive.  Typically the end of August is peak time for White fly hatch and look for best action just before dark.


August 9th - Blizzard hatch of White Flies (Ephron) in the Big Waters of the Au Sable River below Mio.  There were lots of trout up and rising as hatch started around 8pm and trout were fairly easy to catch.  Bugs got so thick around dark that is was very hard to catch a trout at that time.  Look for excellent dry fly fishing for the next few weeks!


Here is Ephron spinner typically size #12 and #14.  The last couple of nights look for bugs to start hatching around 8pm and heavy spinner falls to start around 9pm.  At the beginning of hatch fishing a emerger or wet fly can work very well during this hatch.  When bugs get going strong best to switch over to a spinner pattern.
