san juan fisihing reports

August 14th - [Brad] The San Juan was challenging with the higher water. The better flies were chamois leech and juju baetis.  Flows are still at 800cfs with good clarity. 

Around 2 to 3pm we started to see bwo's coming off at baetis bend with some large fish keying in on them.  For the coming week, we would expect more BWO hatches so be prepared for some dry fly activity. 

August 10th - [Dan] The flows on the San Juan have increased to 800 cfs as of July 9.  This increase will help open up more water for float fishing but be careful when wading, as some of the areas that were previously easy to wade will now be deeper and have faster flows.  

The river continues to fish well, with the better times of day being early (7am-11am) and late (3pm-6pm).  6x continues to be a must, with our better fishing in the morning on midge larva and emergers with cream and chocolate being better colors.  

In the afternoons we are seeing sporadic PMD hatches but the fish are feeding well on #18-20 pheasant tail nymphs as well as #18-20 sparkle baetis.  In the deep water we continue to have good work on small (#12-14) leach patterns including black buggers and micro leechs in olive & black.  

Dry flying has been nice with ant patterns, Griffith Gnats and BWO and PMD parachutes.

August 9th -

As a result of decreasing river flows in the critical habitat area of the San Juan River and a hot and dry forecast, the Bureau of Reclamation will be increasing the release from Navajo Reservoir to 800 cubic feet per second (cfs) on Tuesday, August 9, 2011, beginning at 4:00 a.m.  Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell).

August 8th - [Jerome] The San Juan River (800 cfs) recent increase in flows should swing opportunity in favor of the angler.  We recommend using attractors (chamois leech or small grey scuds) or dead drifting “moss” flies such as bunny leech patterns or woolly buggers as a point fly then dropping to midge larva in grey or cream.  Switch to baetis nymphs in BWO and PMD clothing around noon.  Pheasant tails, hares ears, and foam emergers have fit the mold well. Overcast days with low wind should provide great dry fly options.

August 1st - Large midge hatch throughout the day but strongest around 11am.

Flies: gray foam back, hatching midge, black rs2, scintilla midge.

July 31st - The San Juan fishing has been good with a midge hatch all day!

The best rig was an Indicator six foot from weight. We used small midges. The fly in picture below with stomach sample is sz 26.

Flies: The best fly was Big Mac sz 24 in red and black. A #26 black mono midge also worked well. In the mornings we caught fish with red annelid in morning with olive streamer on top.

The fish are eating moss so dead drifting an olive streamer or bunny leach will work.

July 29th - [Jeremy] San Juan below Navajo Dam. The fishing has been improving lately, with the morning bite being a little better than it has for the last few weeks. Heavy rains this week made the water a little cloudy, and much more forgiving.

My best patterns have been an olive or black wooly bugger to a #20 red larva in the mornings. In the afternoons I have been using a grey RS2 #20 as an attractor, and a #20 grey midge pupa with a black head as my dropper.

There was an epic ant fall on Wednesday, so big black dries will work for a while. One of my favorites is a #10 black stimulator.

July 29th - [Ryan] San Juan (Quality Waters)
Slow periods or Prospecting – black wooly bugger (size 10) with a red larva dropper (size 22)

Midge Hatch – JuJu Baetis (size 20) with a black mercury midge dropper (size 24)

July 28th - [Jerome and Dan] The San Juan River (510 cfs) is fishing well but remains technical.  They recommend fluorocarbon leaders down to 6X.

It is fishing best early (7am-11am) and late (4pm-8pm) with midges working well throughout the day.

There is good dry fly fishing in the afternoons & evening with ants, midge clusters and PMDs on the lower parts of the quality water.

midge larva 20-24 in gray, brown & black
baetis nymphs and emergers #18-22
sparkle-wing RS-2 #18-22
Bling Midge #18-22
Foam Emergers #18-22
Sparkle Baetis #18-22  

Dead drifting streamers and leeches will increase your midge hook-up as well as provide weight to your rig reducing the amount of split needed to get down. 

July 20th - [Jeremy]San Juan below Navajo Dam- fishing has been a little slow in the mornings, but I have been getting fish on size 20 cream pupa, and size 24 grey midge pupa. Black woolly buggers have also fooled a few fish.

I have been having better luck fishing griffiths gnats instead of terrestrials for any dry fly fishing lately.

July 14th - [Dan] The first ant fall occurred last Tuesday on the San Juan. There was a residual fall on Wednesday.  Fishing is still better in the afternoons and into the evenings but we are seeing some of the bigger fish eat in the mornings.

July 8th -[Brad] Flows on the san juan are still about 470 cfs with great clarity. The clarity requires care in choosing a leader because the fish are a little leader shy. Use flouro when nymphing.

The Texas hole fished very well.  It was necessary to use two #1 split shot and long leader to get down to the fish.  The better fishing was in the upper seams which are deeper and hold lots of fish. 

In addition to the lighter leader, it was important to concentrate on perfect drifts. The fish notice the difference.  All fishing was nymphing beneath an indicator.

Flies:  #24 chocolate foam back emerger
          #22 jujubee baetis
          #22 jujubee - blk/wht
          #24 black beauty

The lower section was not as productive but persistence paid. Again it was a matter of nymphing beneath an indicator.

Flies : #20 pheasant tail
         #20 rubber legged hares ear
         #22 FPA sparkle baetis
         #22 jujubee baetis
         #20 barrs emerger

Overall good fishing, but a little technical so take the time to ensure the drift is right, the flies are well positioned and the leaders are long and lighter tippet. Preferably fluoro.

July 7th - [Jerome] The San Juan River is currently at a great level around 470 CFS. It is fishing very well.

At the moment the best results are from nymphing under an indicator. Using tippet down to 6X is recommended because the fish are a touch leadershy. 

Flies: generally use small patterns for nymphs.

# 22-24 RS2 in grey, black, brown.
# 22 Sparkle Baetis
# 22 pheasant tails
# 22-24 jujubee Midge/Baetis.  

There has also been some good dry fly activity. We have been moving large Bows with #4-10 Hoppers and Stimulators.

July 1st. [Dan] - The San Juan is fishing well but technical, with better fishing in the mornings and early afternoon with midges in red & cream in the 22-24 range in the mornings with baetis in olive & chocolate in 18-20 in the afternoons.  

We are seeing some nice work with hoppers in the afternoons as well as select days with BWO dries.

Have a look at the photos of the couple of beautiful fish over the last few days.

June 21st. [Dan] The flows on the San Juan are back down to 500 cfs and the fishing has been very good in recent days.  

The morning bite is a mixture of baetis and midges with #22 sparkle baetis and #24 red midge larva doing equally well.  In the late morning and into the afternoon, various baetis nymphs and emergers have been productive, with #20 sparkle baetis and #20 foam back emergers working very well.  

We are seeing good dry fly fishing in the afternoons, with both hoppers and parachute BWO patterns.

June 19th. A few nice photos over the past few days.

June 18th. [Brian]

Flow: 500 cfs

Overall: Excellent

The releases from Navajo have ended and the flow is back to 500cfs. At the moment the fish, having spread out in the rising waters are moving back to their more traditional feeding positions. While the water has been coming down the fish were tending to stay deep but that is changing by the day.

Fish are feeding on red analids all day long sz 22. Also caught fish on pink egg, chamose leech, and red big mac. With the flow dropping and settling down, soon the fish will be back on midges and baetis as well but the residual food from the releases will persist a little longer.

As the water clears now the fish will begin to notice the tippet. So whereas the rising water was a little colored, be more aware of the potential for tippet to be noticed. So use flourocarbon or lighter tippet if it becomes an issue.

When not targeting risers use a nymph rig with a larger nymph such as rubber legged pattern nymphs as the point fly dropping to smaller midge larva in black, brown, cream, or red and baetis patterns mid-day such as sparkle baetis, fluff baetis, or foam back emergers. 

As always call or stop into the shop for up to date reports and fly selection information.

Principal Biomass:  Midges and BWO’s.  Fish will feed all day, but the BWO’s will be coming of from midday to mid afternoon.

Techniques.  Generally nymphing.  Follow the fish in the water column.  But when they are taking BWO’s off the surface, dry fly action will be strong.

Equipment.  For nymphing #5 or #6 and 9 ‘ – 10’ length.

Tippet:  Down to 6x.  In the darker water, go heavier as the fish will be less likely to see.  In addition use flouro to help disguise the line.

Recommended Flies:

For midges: 
Black and grey biot emergers #20 - #26
WD 40 – black and red - #20 – 24
Red larva #18 – 24
Chocolate midge pupa - #20 - #24

For baetis and BWO’s:
Parachute Adams - #18 - #26
Parachute BWO - #18 - #26
FPA Sparkle baetis #18 - #24
Pheasant tails - #18 -#24
Lightning bugs [in murkier water] #18 - #24
