Jun 16 FlyCast River Forecast

Technicality: 3/5

Flows on the Blue continue to rise, but are generally in line with historical averages for this time of year. Increased water levels will allow trout to spread out making sight fishing even more important. With lower flows, trout tend to podd up in the same hole making blind casting fairly productive. Dont expect trout to congregate in numbers this week. Focus on the banks, areas with structure and the undercuts. Cover a lot of water and locate holding trout before aimlessly casting. The heavy nymph rig will continue to be your primary mode of fishing. Mysis shrimp are being released from the dam in large quantities so make sure to have a few on hand. Otherwise, lead with bigger stoneflies or worms followed by bigger search patterns like Copper Johns or Pheasant Tails. Productivity on smaller midge and baetis flies has been limited as trout are generally opportunistic and are feeding are bigger bugs. Hatch activity should be consistent and strong throughout the week so be prepared to fish some dries. However, only cast to actively feeding trout and focus on areas with cover, particularly near the bank, outer seams and tailouts.

Ideal Days to Fish: Monday, Tuesday, Friday & Saturday

Jun 11 FlyCast River Forecast

Technicality: 3/5

On Tuesday, flows on the Blue jumped roughly 200 cfs to 600 cfs. As such, trout are keyed in on bigger bugs like worms, stoneflies, leeches and most importantly mysis shrimp. Trout here are generally selective. However, they will be more opportunistic over the next few days with fresh food sources from the reservoir. Water clarity is still in good shape so do your best to sight fish. In general, we are not casting unless we see holding trout.The heavy nymph rig will be your best bet this week. Lead with bigger attractor patterns followed by one or two smaller midge, baetis or caddis pupa/larva patterns. Less is more so keep it simple when it comes to your flies. Trout will hold in the slack water near the banks in the morning and as the day progresses they will migrate towards the slower and deeper runs and pockets. Hatch activity will be strong and consistent this week. However, your best bet for fishing dries will be Thursday through Sunday. Midges will hatch consistently throughout the day while BWOs and caddis will hatch in the afternoon.

Jun 09 FlyCast River Forecast

Technicality: 3/5

Consistent flows and increasingly mild weather has made for some great days on the Blue. Trout here are generally selective, so you'll need to be persistent. Water clarity is good, so do your best to sight fish. In general, we are not casting unless we see holding trout.The heavy nymph rig will be your best bet this week. Lead with bigger attractor patterns like a San Juan Worm, mysis shrimp, or stonefly followed by one or two smaller midge, baetis or caddis pupa/larva patterns.

Jun 02 FlyCast River Forecast

Technicality: 3/5

Not much has changed in the last couple weeks. However, productivity has been great. Flows have held steady at 400 cfs leaving trout with a variety of holding places and abundant food sources. Now that winter is gone, bigger bugs are the name of the game. Mysis shrimp, stoneflies, worms, and leeches have all made for great point flies, especially close to the dam. Trail any of the aforementioned flies with smaller midge, baetis or caddis pupa patterns. By and large, weve had the most success on the heavy nymph rig, but you can still have luck on dries. When fishing dries, focus on areas with cover like low hanging trees, bushes and bridges. Make sure to have some midge, BWO and caddis patterns in your arsenal. Despite a strong chance of rain, early in the week will put you at the best odds. Productivity will decline starting on Friday and lasting through the weekend.

Ideal Days to Fish: Monday through Thursday

May 29 The Blue Quill Angler

Clarity: Excellent in Silverthorne

14 Day Forecast: Look for intermittent hatches of midges and a sporadic blue winged olive or two

Tips and Other Information: Flows are above their normal historic levels in preparation of a huge run off. In town, a Mysis pattern, red larva, dropped with and assortment of mayfly nymphs are your best bet right now. Fishing overall on the Blue River has been a disappointment as of late, as the number of trout are way down. Your best bet is to fish in town and sight fish to increase your odds of hooking fish. Anglers who are blind fishing are not enjoying much success. Look for the lower river to be influenced by runoff and fishing will be difficult until the river begins to recede.

Effective Patterns: #20 Juju Baetis, #20 Choc Foam Wing Emerger, #22 Stalcups Baetis, #20-22 Mercury Midge, #20-22 Manhattan Midge, #20 Pale Olive Midge Larva, #22-24 Black Beauty, #22-24 Bling Midge, #22-24 Top Secret Midge, #22-24 Minute Midge, #22-24 Jujubee Midge, #22-24 Matts Midge, #22-24 Griffith Gnat, #20 Sparkle Dun, and #24-26 Parachute Adams.

May 28 FlyCast River Forecast

Technicality: 3/5

Colorado is holding on to spring for dear life. Rain and snow continues to fall, making for less than ideal fishing conditions. While this will continue into the early part of the week, moisture in the air has led to some great hatch activity and some productive days on the water. Trout are holding in the slack water near the banks and deep pools in the early hours. However, as the air temp rises and bugs start to come off the water, trout will spread out into the deeper runs, riffles and tailouts. The double and triple nymph rig will be your go-to mode of fishing. Early in the week, lead with larger search patterns, caddis larva or a Mysis Shrimp followed by one or two smaller imitative nymphs. As the day progresses swap out your trailer flies for an emerger pattern. Dark reds, purple and green have all been productive colors. Remember to keep it simple though. A standard thread midge more often than not does the trick. Assuming the rain holds off for periods of time, you can expect some decent hatch activity. Be prepared to fish midge, BWO and caddis patterns along the banks and in areas with cover.

Ideal Days to Fish: Wednesday, Thursday & Friday
