Aug 09 FlyCast River Forecast

Difficulty: Intermediate/Advanced

Flows are up and holding steady at 340 cfs. At this level, clarity is off and the river is moving quickly in the narrower sections. Unless youre fishing during the warmest hours of the day, youll find most trout stacked up in slow pools, along outer seams and banks. Hopper droppers and nymph rigs will do the trick in this situation. During the middle of the day, trout will slide towards the middle of the river, but youll need heavy weight to fish the fast water effectively. We fished Deckers last Saturday and found ourselves using two large split shots in certain sections. Large and/or flashy patterns are attracting attention right now. Think Pats Rubber Legs, UV Scuds, Electric Caddis, Copper Johns, Flashback Pheasant Tails and Rainbow Warrriors. These are great lead patterns for your nymph rig. Trout were keyed in on baetis emergers last weekend, favoring the patterns with flash. Olive Sparkle Wing RS2s and Barrs Emergers were the MVPs. We saw some solid evening hatch activity but didnt find trout feeding on the surface.

Ideal Days to Fish: Monday, Saturday & 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 PMD (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Candy Caddis (#16-18), Sparkle Pupa (#16), 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.

Aug 09 FlyCast River Forecast

Difficulty: Advanced

Flows are up, water temps are cool and the water color is slightly stained in Cheesman Canyon. Cool water temps will provide trout with more energy throughout the day and slightly off-color water will make trout a little less spooky. Elevated flows, however, will require you to make adjustments. Hopper droppers and dry droppers are working along the banks and outer seams, but other than that, heavy nymph rigs are the key. Amys Ants, All Season Caddis and Parachute Adams are attracting trout looking up. Sub-surface, scuds, Pats Rubber Legs, crane fly larva and Mercury Flashback Pheasant Tails have been hot lead patterns. Sparkle Wing RS2s, Darth Baetis, Barrs Emergers and Mercury Midges are hot trailers. If youre not seeing any action, odds are you arent getting your flies down quickly or deep enough. Adjust your split shot and indicator placement so that your flies get down into the deepest water column where the current is slowest. If youre not getting snagged every few casts, add more weight.

Ideal Days to Fish: Monday, Saturday & Sunday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu PMD (#20), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), 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), Candy Caddis (#16-18), Sparkle Pupa (#16), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Aug 05 FlyCast River Forecast

Difficulty: Intermediate/Advanced

Flows through Deckers increased again this week by 100 cfs. A sharp increase like this will throw off trout behavior for a few days, but once trout settle in, fishing will be highly productive. At 300 cfs, flows are at a great spot for this time of year. Healthy flows will help stabilize water temps, provide trout with plenty of bugs to feed on and allow trout to move throughout the day. During the morning and evening hours, focus on the banks, outer seams, tailouts, slow pools and runs. From 1 pm 4 pm, focus on the faster moving water. Riffles and transition areas continue to produce fantastic results during the middle of the day. As far as patterns go, scuds, Mini Leeches, Pats Rubber Legs, Copper Johns and Prince Nymphs are productive lead patterns. For your trailer, caddis pupa and flashy baetis/midge emerger patterns will do the trick. Other than nymphing, hopper droppers fished between the outer seams and banks will pick up trout looking up or feeding in the middle column.

Ideal Days to Fish: Monday, Saturday & 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 PMD (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Candy Caddis (#16-18), Sparkle Pupa (#16), 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.

Aug 05 FlyCast River Forecast

Difficulty: Advanced

Cheesman Canyon flows jumped again this week from 200 cfs to 300 cfs. Due to a rapid change in flow, trout will take 2-3 days to normalize. So, if youre on the river today or tomorrow and have a hard time dialing it in, this is likely why. Starting Thursday or Friday, trout will normalize and become more predictable. Tight runs and pools will require a heavy nymph rig in order to get your flies down quickly. In the wider stretches, weight will still be important but not as critical. Other than nymphing, hopper droppers (Amys Ants or Hippy Stompers) will produce results along the outer seams and banks. Hot sub-surface patterns right now are UV Scuds, Mini Leeches, Guides Choice Hares Ears, Flashback RS2s, Barrs Emergers and Mercury Pheasant Tails.

Ideal Days to Fish: Monday, Saturday & Sunday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu PMD (#20), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), 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), Candy Caddis (#16-18), Sparkle Pupa (#16), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Aug 01 FlyCast River Forecast

Difficulty: Advanced

After a summer of low flows and high water temps, Cheesman Canyon increased last week by 120 cfs. Flows increased in a stair step fashion, with the most recent increase occurring on Friday. As a result, fishing was been hit or miss, but productivity should improve Monday. Trout will normalize and spread out throughout the day. Tight runs and pools will require a heavy nymph rig in order to get your flies down quickly. In the wider stretches, weight will still be important but not as critical. Other than nymphing, hopper droppers (Amys Ants or Hippy Stompers) will produce results along the outer seams and banks.

Aug 01 FlyCast River Forecast

Difficulty: Intermediate/Advanced

To our surprise, flows through Deckers rapidly increased last week. Before the start of last week, flows sat at 80 cfs and now sit just below 200 cfs. Until flows stabilize, fishing will be hit or miss. In general, trout take a few days to adjust to flow increases, so be patient, test different water and pattern sizes. Trout will spread out and adjust their holding position throughout the day. Prior to 11 am, focus on the slack water, banks, pools and tailouts. After 11 am, trout will slide into faster water (riffles, pockets, runs, transition areas). One of the most important factors right now is weight. To account for increased flows, start with ample weight to get your flies into the deepest water column. If youre getting snagged every few drifts, you have enough weight. When you move into faster water, consider adding a little more weight. As far as patterns go, scuds, Mini Leeches, Pats Rubber Legs, Copper Johns and Prince Nymphs are productive lead patterns. For your trailer, caddis pupa and flashy baetis/midge emerger patterns will do the trick. Other than nymphing, hopper droppers fished between the outer seams and banks will pick up trout looking up or feeding in the middle column.

Jul 30 The Blue Quill Angler

Clarity: Excellent

14 Day Forecast: Look for hatches of midges, PMDs, and caddis

Tips and Other Information: Flows are low considering the time of year. The South Platte at Deckers is currently running at about 94 cfs, as the tributaries are adding some additional water. Cheesman Reservoir is 18,000 Acre Feet from full pool (75% full), so expect low flows for a while. The good news is Spinney Reservoir is full, Eleven Mile Reservoir is at 103 percent, and Tarryall Creek is dumping in 120 cfs into the South Platte above Cheesman Reservoir. Currently inflows are about 450 cfs, which is great news. In the mean time, anglers can plan on good fishing despite the low water. Look for strong hatches of midges, sporadic BWOs, PMDs, and excellent caddis. The caddis fishing has been something to talk about lately. The South Platte trout are feasting on caddis pupae as well as adults in riffled water. Its hard to go wrong with Graphic Caddis and Elk Hair Caddis to match the hatch. Water temps have been in the mid 40s during the morning, but rising quickly the low 60s mid afternoon. Please pinch your barbs and release the trout quickly. Keep them in water as much as possible and try to keep your photos (especially grip and grins) to a minimum until the flow improves. Its important to quit fishing once the water temperature reaches 65 degrees, so start early and finish early to protect this valuable resource.

Effective Patterns:#20-22 Medallion Midge, #20-22 Mercury Midge, #22-24 Black Beauty, #20-22 Manhattan Midge, #20-24 Top Secret Midge, #22-24 Chocolate Foam Wing Emerger, #20 JujuBaetis, #22 Stalcups Baetis, #20 Mercury Flashback PT, #20 Sparkle Wing RS 2, #18 Hot Tail Flash Egg, #16 Barrs Graphic Caddis, #16 Elk Hair Caddis, #20-22 Griffith Gnat, #20-22 Matts Midge, #20-22 Sparkle Dun, #20-22 Blue Dun, #20-22 Blue Quill, and #20-24 Parachute Adams.

Jul 30 The Blue Quill Angler

Clarity: Excellent

14 Day Forecast: Look for low flows until Cheesman Reservoir fills. Anglers can expect strong hatches or midges and sporadic Blue-Winged Olives.

Tips and Other Information:Flows are low considering the time of year. Cheesman Reservoir is 18,000 Acre Feet from full pool (75% full), so expect low flows for a while. The good news is Spinney Reservoir and Eleven Mile Reservoir are full, so incoming flows are now approaching 450 cfs. Pray for a good monsoon season to assist in filling Cheesman Reservoir. In the mean time, anglers can plan on tougher than normal fishing. Look for strong hatches of midges and sporadic BWOs and caddis. Water temps have been in the mid 40s during the morning, but rising quickly the mid 50s mid afternoon. Please pinch your barbs and release the trout quickly. Keep them in water as much as possible and try to keep your photos (especially grip and grins) to a minimum until the flow improves

Effective Patterns: #20-22 Medallion Midge, #20-22 Mercury Midge, #22-24 Black Beauty, #20-22 Manhattan Midge, #20-24 Top Secret Midge, #22-24 Chocolate Foam Wing Emerger, #20 JujuBaetis, #22 Stalcups Baetis, #20 Mercury Flashback PT, #20 Sparkle Wing RS 2, #18 Hot Tail Flash Egg, #16 Graphic Caddis, #16 Elk Hair Caddis, #20-22 Griffith Gnat, #20-22 Matts Midge, #20-22 Sparkle Dun, #20-22 Blue Dun, #20-22 Blue Quill, and #20-24 Parachute Adams.

Jul 26 FlyCast River Forecast

Difficulty: Advanced

Similar to Deckers, flows continue to hold on the low end, so anglers should focus on the morning and evening hours for the most action and to protect the trout. With low flows and warm water temps, our favorite windows have been 8 am 12 pm and 5 pm 8 pm. During those low light hours, youll find trout holding between the outer seam and bank. Dry droppers are a great option in that scenario. You can either lead with a Parachute Adams or Amys Ant and trail a Barrs Emerger or Mercury Midge. Those setups are also productive when fishing the shallow riffles in the late morning. Aside from that, trout are stacked up in the pronounced pools, runs, riffles and pockets. With low flows and high water clarity, yarn indicators or a deep dry dropper setup is recommended. For a deep hopper dropper setup, lead with an Amys Ant and tie on 2-3 ft of tippet to your first nymph. From there, add an additional 12-18 of tippet to your trailer pattern. Sub-surface, small midge, baetis and searcher patterns have been the most productive.

Ideal Days to Fish: Monday, Thursday & Friday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), Chocolate Foam Wing Emerger (#22-24), JuJu PMD (#20), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), 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), Candy Caddis (#16-18), Sparkle Pupa (#16), red Copper John (#18-20), Rainbow Warrior (#18-20), Pat's Rubber Legs, pink/green scud, leech pattern and San Juan Worm.

Surface: Parachute Adams (#20-22), Parachute PMD (#20-22), Sparkle Dun (#20-22), Griffiths Gnat (#22-24) and Elk Hair Caddis (#16-18).

Jul 26 FlyCast River Forecast

Difficulty: Intermediate/Advanced

Flows through Deckers continue to hold steady at 86 cfs. At this level, trout are primarily holding in the deeper and faster water. Early mornings you may find trout holding along the banks, but for the most part, focusing on the runs, transition areas, pockets and riffles is the way to go. When fishing the faster water, heavy double or triple nymph rigs are productive. If youre fishing during a storm or during low pressure, large lead patterns will attract trout. Otherwise, simple double midge, double baetis or midge/baetis rigs are the way to go. Some of our go-to patterns right now are Mercury Midges, Pale Ale Midges, Chocolate Foam Back Emergers, RS2s, Barrs Emergers and Pheasant Tails. Hatch activity has been relatively consistent during the morning and evening, so be prepared to fish dries if youre on the river during those hours. Small Parachute Adams, Parachute Tricos and Sparkle Duns are the dry patterns we have in our box right now.

Ideal Days to Fish: Monday, Thursday & 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 PMD (#20-22), JuJu Baetis (#20-22), Mercury Pheasant Tail (#20-22), WD 40 (#20-22), Electric Caddis (#16-18), Candy Caddis (#16-18), Sparkle Pupa (#16), 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.

Surface: Parachute Adams (#20-22), Sparkle Dun (#20-22), Parachute PMD (#20-22), Griffiths Gnat (#22 - 24) and Elk Hair Caddis (#16-18).
