Oct 21 FlyCast River Forecast

Difficulty: Advanced

Flows through Cheesman Canyon stabilized over the past week and as a result, productivity improved. With flows holding at 50 cfs, anglers should approach the river with a winter mindset: light tippet, clean drifts and small bugs. While you may see some surface activity during a midge or BWO hatch, the most action is sub-surface. Egg patterns, San Juan Worms, Buckskin Caddis, midge and baetis patterns are turning heads. Eggs, worms and caddis larva patterns will perform best as a lead attractor if trout arent responding to your midge and baetis patterns. Due to the brown trout spawn, worms, eggs and red nymphs (red Copper John, Rojo Midge, red Zebra) are hot commodities. For midge and baetis patterns, you cant go wrong with a Mercury Midge, Top Secret, Manhattan Midge, Rojo Midge, Chocolate Foam Back Emerger, JuJu Baetis or olive RS2. Unless youre on the river during a warm afternoon, focusing on pronounced pools, runs and soft seams will produce the best results. While you dont need a ton of weight to get your flies down right now, depth is still very important.

Ideal Days to Fish: Monday, Tuesday & Friday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Top Secret Midge (#22-24), Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Guides Choice Hares Ear (#16-18), Electric Caddis (#16-18), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 21 FlyCast River Forecast

Difficulty: Intermediate/Advanced

For the past week, flows through Deckers held steady at 50 cfs. Despite low flows, high water clarity and technical fishing, this stretch has been productive. The recipe for success is a long leader, 5x fluorocarbon tippet, clean drifts and small midge/baetis patterns. We are entering the time of year when trout wont be fooled easily, so take your time scouting the river and get yourself into a good position to make clean casts and drag-free drifts. One thing to be considerate of is the brown trout spawn. Redds (spawning beds) are prevalent, so please avoid stepping on and casting to trout on redds. If you dont know what a redd looks like, look for a clean patch of gravel. Due to the spawn, egg patterns and San Juan Worms are highly productive point flies right now. Trail a midge larva/pupa or baetis emerger behind one or both of those patterns and hit the deep pools and runs. If youre on the river during a warm afternoon, slow riffles and transition areas are good sections to hit as well. Some of our favorite midge and baetis patterns are Mercury Midges, Top Secrets, Rojo Midges, Manhattan Midges, JuJu Baetis and olive RS2s.

Ideal Days to Fish: Monday, Tuesday & Friday

Suggested Flies:

Sub-surface: Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Top Secret Midge (#22-24), Manhattan Midge (#22-24),RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Guides Choice Hares Ear (#16-18), red Copper John (#18-20), Rainbow Warrior (#16-28), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 14 FlyCast River Forecast

Difficulty: Advanced

Flows through Cheesman Canyon dropped off over the last few days and as a result, anglers should expect highly technical fishing. With flows sitting at 50 cfs, trout are stacked up in pronounced pools, runs and pockets. Trout will spread out towards transition areas, riffles and tailouts during hatches and when water temps rise, but other than that, your time is best spent targeting deeper water. In addition to that, anglers should decrease their tippet size to 5x or 6x fluorocarbon tippet, use yarn indicators when nymphing and focus on smaller patterns. With the current flows, San Juan Worms, eggs, red searchers and red midge patterns will be the most productive point flies. Small midge and baetis patterns will serve well in the trailer position. Size 20 24 Black Beauties, Jujubee Midges, Manhattan Midges, Foam Back Emergers, RS2s and WD40s are all good examples. If youre not seeing results, swap out your lead fly for a size 22 midge larva. When in doubt, size it down. Aside from nymphing, we expect to see productive dry fly opportunities during the morning and early afternoon.

Ideal Days to Fish: Tuesday, Friday & Sunday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Top Secret Midge (#22-24), Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Guides Choice Hares Ear (#16-18), Electric Caddis (#16-18), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 14 FlyCast River Forecast

Difficulty: Intermediate/Advanced

Over the last few days, flows through Deckers dropped by nearly 400 cfs. Currently sitting at 70 cfs, the river looks very different than it did the past few months and as a result, anglers will need to make adjustments. With low flows, 5x and 6x fluorocarbon tippet is highly recommended. Long leaders, yarn indicators and clean presentations will be necessary as well to fool these trout. From a bug perspective, we still expect San Juan Worms and eggs to be productive, but leeches will be hit or miss. Aside from those patterns, trout will respond best to small offerings. Size 18 22 Buckskin Caddis, red Copper Johns, Rainbow Warriors, Blood Midges, Disco Midges and Rojo Midges are our go-to point flies when nymphing if trout arent responding to larger offerings. For your trailer, go even smaller with size 20 24 midge pupa and baetis emergers. When flows drop and water clarity increases, these trout become highly selective and weve learned that smaller is often better in these circumstances. One positive to this decrease is we should see more consistent hatch and surface activity. Midges and BWOs have the biggest presence right now, so make sure you have plenty of Griffiths Gnats and Parachute Adams on hand. Targeting deep pools, runs, pockets and transition areas will produce the best results right now when nymphing.

Ideal Days to Fish: Tuesday, Friday & Sunday

Suggested Flies:

Sub-surface: Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Top Secret Midge (#22-24), Manhattan Midge (#22-24),RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Guides Choice Hares Ear (#16-18), red Copper John (#18-20), Rainbow Warrior (#16-28), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 11 FlyCast River Forecast

Difficulty: Intermediate/Advanced

Over the weekend, flows through Deckers dropped significantly and currently sit at 207 cfs. At this level, trout wont be confined to the soft water and will spread out as the day progresses. The slow water sections are still great sections to target during the morning but as soon as water temps rise and hatches materialize, trout will move into their feeding lies (seams, riffles, tailouts, runs and transition areas). San Juan Worms, leeches, eggs, Blood Midges and Rainbow Warriors are great point flies at the moment. Below one of those patterns, trail one or two midge or baetis patterns. Mercury Midges, Black Beauties, Top Secret Midges and Jujubee Midges are the top producing midge patterns. For baetis patterns, you cant go wrong with RS2s (black in the morning and grey/olive in the afternoon), Chocolate Foam Back Emergers, WD40s, Stalcups Baetis and Mercury Pheasant Tails. While nymphing is the most consistent approach, dont rule out dry flies or streamers. This stretch has experienced heavy and sporadic midge hatches and BWO hatches during the late morning and early afternoon. Griffiths Gnats and Parachute Adams are must haves during these hatches. If youre looking to fish streamers, the low light hours and overcast days are ideal.

Ideal Days to Fish: Tuesday, Friday & Sunday

Suggested Flies:

Sub-surface: Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Top Secret Midge (#22-24), Manhattan Midge (#22-24),RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Guides Choice Hares Ear (#16-18), red Copper John (#18-20), Rainbow Warrior (#16-28), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 11 FlyCast River Forecast

Difficulty: Advanced

Flows dropped off in Cheesman Canyon and currently sit at 200 cfs. This decrease puts this stretch at a much more productive level for this time of year. Nymph rigs will continue to be the most productive approach, but due to consistent midge and BWO hatches, dry fly fishing is certainly an option. Be on the lookout for midges during the mid-morning and evening hours. From 11 am 2 pm, keep an eye out for BWOs. Griffiths Gnats rarely let us down during midge hatches and a #22-24 Parachute Adams is a fantastic pattern during the BWO hatch. Slow pools, eddies, slack water and tailouts are where we tend to find rising trout. If trout arent rising, stick with a nymph rig. Top Secret Midges, Black Beauties, Jujubee Midges and black RS2s have been lights out trailer patterns during the morning and late afternoon. During the middle of the day, swap out your midge trailer for an olive/grey RS2, WD40, Barrs Emerger or Darth Baetis. In regards to lead patterns, we recommend going with a large or flashy pattern. Trout are feasting on San Juan Worms, leeches, eggs, Rainbow Warriors, red Copper Johns and blood midges. Due to lower flows, trout won't favor the soft water as much as they were the past few weeks. While deep pools and runs are always great sections to fish, we highly recommend targeting pockets, riffles, transition areas and faster runs after 11 am.

Ideal Days to Fish: Tuesday, Friday & Sunday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Top Secret Midge (#22-24), Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Guides Choice Hares Ear (#16-18), Electric Caddis (#16-18), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Difficulty: Advanced

Despite elevated flows, Cheesman Canyon has been fun and productive. With flows sitting in the low 400 cfs range, heavy nymph rigs have been the most productive but due to consistent midge and BWO hatches, dry fly fishing is certainly an option. Be on the lookout for midges during the mid-morning and evening hours. From 11 am 2 pm, keep an eye out for BWOs. Griffiths Gnats rarely let us down during midge hatches and a #22-24 Parachute Adams is a fantastic pattern during the BWO hatch. Slow pools, eddies, slack water and tailouts are where we tend to find rising trout. If trout arent rising, stick with a nymph rig. Top Secret Midges, Black Beauties, Jujubee Midges and black RS2s have been lights out trailer patterns during the morning and late afternoon. During the middle of the day, swap out your midge trailer for an olive/grey RS2, WD40, Barrs Emerger or Darth Baetis. In regards to lead patterns, we recommend going with a large or flashy pattern. With elevated flows, trout are feasting on scuds, San Juan Worms, leeches and caddis larva. Rainbow Warriors, red Copper Johns and blood midges are good alternate patterns if you need a little flash to get their attention. Slow and deep pools/runs are holding a lot of trout right now, so spend some time in those sections until you dial it in. In addition to the pronounced sections, riffles, pockets and transition areas are producing results during the afternoon.

Ideal Days to Fish: Monday, Tuesday & Wednesday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Top Secret Midge (#22-24), Mercury Midge (#22-24), Black Beauty (#22-24), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Guides Choice Hares Ear (#16-18), Electric Caddis (#16-18), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Oct 07 FlyCast River Forecast

Difficulty: Intermediate/Advanced

On Tuesday, flows dropped from 500 cfs to 450 cfs. This small reduction in flow wont have a material impact on your approach but it will slightly improve water clarity. At the current level, nymphing is our preferred approach. Trout are feeding heavily in the soft water during the morning and evening. During the afternoon, trout will slide into the faster moving runs, slow riffles, transition areas and tailouts. Scuds, San Juan Worms, leeches, caddis larva and Rainbow Warriors are great point flies at the moment. Below one of those patterns, trail one or two midge or baetis patterns. Mercury Midges, Black Beauties, Top Secret Midges and Jujubee Midges are the top producing midge patterns. For baetis patterns, you cant go wrong with RS2s (black in the morning and grey/olive in the afternoon), Chocolate Foam Back Emergers, WD40s, Stalcups Baetis and Mercury Pheasant Tails.
