Aug 20 The Blue Quill Angler

Clarity: Excellent

14 Day Forecast: Look for the flows to drop dramatically as Denver Water prepares to ramp up flows on the North Fork. Anglers should prepare for hatches of golden stoneflies, PMDs, and blue-winged olives.

Tips and Other Information: Look for flows to drop as Denver Water prepares to move water from Dillon Reservoir via the Roberts Tunnel. Cheesman Reservoir is down to 95% of capacity which is alarming after a huge snow pack. To the contrary, Dillon is at 101% capacity, so Denver Water will service their customers on the Front Range and outlying areas with water from Summit County. Anglers should prepare themselves for hatches of midges, caddis, blue-winged olives, PMDs, golden stones and Tricos. Amys Ant continues to produce some great fish on top, and a dry and dropper rig is never a bad idea, especially in the skinny water.

Note: Water temps are a concern as they are in the lower 60s to upper 60s. Myself and colleagues have been seeing dead fish at Deckers which is a sure sign the high water temps are stressing fish. Dont not play your fish to exhaustion, and release them as quick as possible to fight another day. Keep and eye on the water temps as the volume is reduced, the temps will rise quickly. Its best to start and finish early! Everyones helps is greatly appreciated!

Effective Patterns: #22 Stalcups Baetis, #14-16 San Juan Worm, #14-16 UV Scud, #16-18 red Copper John, #20-22 Juju Baetis, #20-24 Chocolate Foam Wing Emerger, #18-20 Mercury Pheasant Tail, #20-24 RS 2, #18-20 Buckskin, #18 Mitchells Split Case PMD, #18 Barrs Emerger (PMD) #16 Barrs Graphic Caddis, #16 Mercers Swing Caddis, #14-16 Elk Hair Caddis, #16 Yellow Sally #16 Stimulator, #18-20 Sparkle Dun, and #20-22 Parachute Adams.

Aug 19 FlyCast River Forecast

Technicality: 4/5

Flows increased last week and continue to hold at 539 cfs. The fast rise in flow pulled trout away from the center of the river and consolidated them in the soft water along the banks. While you may find a couple pools/runs slow enough to hold trout, the majority of the action will be along the outer seams and banks. Dry dropper and hopper dropper setups have been highly effective when targeting trout along the banks. The Amys Ant has been our go-to dry fly pattern when running a dropper off the back. Lead with an Amys Ant and trail either a San Juan Worm, scud, Pats Rubber Legs or PMD Emerger. If youre nymphing the outer seams, a heavy nymph rig will do the trick. Dont be stingy with the weight and dont be afraid to lead with a large pattern. Increased flows have trout keying in on stoneflies, worms, crane fly larva, caddis larva and scuds. Pink and green scuds in particular have been highly productive. Trailing one or two baetis/PMD emergers behind one of those patterns will pick up trout in the late morning and early afternoon.

Ideal Days to Fish: Tuesday, Wednesday & Thursday

Aug 19 FlyCast River Forecast

Technicality: 4/5

Flows rose last week by roughly 200 cfs. At 511 cfs. trout have pushed back towards the banks and outer seams. Unless you can find a slow pool or run, we recommend focusing your efforts on the outer sections of the river. Trout are keying in on large bugs above and below the surface. Above the surface, Chubby Chernobyls and Amys Ants will work well when trailed with a San Juan Worm, Pats Rubber Legs or PMD Emerger. When nymphing, lead with a large pattern such as a Pats Rubber Legs, San Juan Worm, crane fly larva or scud. Pink and green scuds have been particularly productive. Below one of those larger patterns, trail one or two baetis/PMD emergers. Allowing your line to swing at the end of the drift will encourage strikes on the emergers.

Ideal Days to Fish: Tuesday, Wednesday & Thursday

Aug 16 FlyCast River Forecast

Technicality: 4/5

Ideal flows proved to be short lived. The dam opened up on Tuesday, increasing Cheesman Canyon flows from 367 cfs to 539 cfs. This sharp increase pulled trout away from the center of the river and consolidated them in the soft water along the banks. While you may find a couple pools/runs slow enough to hold trout, the majority of the action will be along the outer seams and banks. Dry dropper and hopper dropper setups have been highly effective when targeting trout in the slow and shallow water. The Amys Ant has been our go-to dry fly pattern when running a dropper off the back. Lead with an Amys Ant and trail either a San Juan Worm, scud, Pats Rubber Legs or PMD Emerger. If youre nymphing the outer seams, a heavy nymph rig will do the trick. Dont be stingy with the weight and dont be afraid to lead with a large pattern. Increased flows have trout keying in on stoneflies, worms, crane fly larva and scuds. Pink and green scuds in particular have been highly productive.

Aug 11 FlyCast River Forecast

Technicality: 4/5

Sitting at 342 cfs, flows through Deckers are in the money zone. Prior to the drop in flow, trout were hugging the banks but are now able to spread out across the river. Along with the banks and outer seams, the deep pools and runs will hold trout during the morning hours. In the afternoon, target the head of runs and riffles. Trout love to feed in the faster water when temperatures rise. Hopper droppers and dry droppers are still effective methods when fishing the near the banks. Aside from that, double/triple nymph rigs will pick up plenty of trout in the deeper and faster water. PMD and baetis patterns have been the key lately, but if youre struggling to get the trouts attention, swap out your lead fly for a Pats Rubber Legs, Guides Choice Hares Ear or caddis larva. JuJu PMDs, Barrs Emergers, olive RS2s, Chocolate Foam Wing Emergers and Black Beauties are all must haves right now.

Ideal Days to Fish: Tuesday, Wednesday & Thursday

Suggested Flies:

Sub-surface: red Copper John (#18-20), RS2 (#20-22), JuJu Baetis (#22-24), JuJu PMD (#20-22), WD 40's (#22-24) Chocolate Thunder (#20-22), Barr's Emerger (#20-22), Pheasant Tails (#18-22), Black Beauty (#22-24), Zebra Midge (#18-22), Mercury Midge (#22-24), Top Secret Midge (#22-24), Disco Midge (#22-24), Electric Caddis (#16-18), Super Pupa (#16-18), Rainbow Warrior (#20-22), Pats Rubber Legs (#10-12), Little Yellow Sloan (#14-16), leech patterns, scuds and San Juan Worms.

Aug 11 FlyCast River Forecast

Technicality: 4/5

Flows came down over the weekend and currently sit in-line with the historical average. As a result, water clarity has increased and trout are now able to spread out and feed in various sections of river throughout the day. Dry droppers along the banks will still produce results, but dont be afraid to cover a lot of water. If youre targeting the banks and outer seams, rig up an Amys Ant followed by a PMD or baetis emerger. Other than that, nymph rigs will get you on the most fish. The reduction in flow has trout keying in on smaller bugs right now, so we recommend starting with a double baetis/PMD nymph rig. If thats not getting the job done, lead with a scud, caddis larva, Prince Nymph or Hares Ear.

Ideal Days to Fish: Tuesday, Wednesday & Thursday

Suggested Flies:

Sub-surface: RS2 (#20-22), Barr's Emerger (#20-22), JuJu PMD (#20-22), Chocolate Thunder (#22-24), JuJu Baetis (#20-22), Pheasant Tail (#20-22), WD 40 (#20-22), Mercury Midge (#22-24), Black Beauty (#22-26), Zebra Midge (#20-24), Blood Midge (#20-22), Disco Midge (#20-22), Electric Caddis (#16-18), Super Pupa (#16-18), Pats Rubber Legs (#10-12), Little Yellow Sloan (#14-16), leech pattern and San Juan Worm.

Aug 07 The Blue Quill Angler

Clarity: Excellent

14 Day Forecast: Look for the flows to return to their normal historic levels soon. Anglers should prepare for hatches of golden stoneflies, caddis, yellow sallies, and PMDs.

Tips and Other Information: Cheesman Dam quit spilling two days ago and currently all the water is flowing off the bottom of the lake.
