Big fish still being caught with a little more effort, Lots of stocker action keeping things busy. Try Rapala, Tas Devil and Kastmasters. Many baits are working. Kokanee fishing is poor with no reports of any good luck. Northern Pike fishing is fair to good. The action is sporadic but hot when it happens. Try Rapala, Daredevil and big sticks trolling 10 feet of water mostly West."

Cheesman Canyon

As of 6/4/2021, fishing Cheesman Canyon is fishing very well producing regularly. Right now, be sure to cover as much water as possible, making sure to fish an entire pool before moving on to another or a different riffle. Starting with small insects is producing the best but larger patterns have also attracted hits. Flows: 204 CFS above Cheesman Lake (6/4/2021)

Conditions Report - Southeast Colorado

Arkansas River - Leadville to Buena Vista

As of 6/2/2021, Braden Baker with Ark Anglers writes, "Flows have dropped slightly following cooler, overcast weather and the upper river is in very good condition for this time of year, with several feet of clarity and very good wade fishing flows. The cloud cover prompted some good blue winged olive hatches early this week, and the terrain is prime for dry-dropper fishing. As the daily snowmelt cycle ramps up, clarity will typically be best in the upper river after lunchtime as flows begin their daily downward trend and reach their daily low. Hayden Meadows has been fishing well and with far less traffic than you'd see around Salida. Fish attractor dry-dropper rigs in the pockets, edges, and riffles. Golden stone and yellow sally nymphs, caddis pupa, baetis nymphs, or attractor nymphs have been effective in this role under a large dry fly. Once runoff kicks back into gear, fishing opportunities are still possible in the upper reaches of the river although you may need to cover more water to find good holding positions. Focus on fishing the velocity shelters near the banks where fish can hold to avoid the fast flows. During this time, big dry flies and streamers in the soft water areas can still be productive." Flows: 307 CFS at Hayden Meadows, 410 CFS at Granite (6/4/2021) http://www.arkanglers.com/
Arkansas River - Leadville to Buena Vista

Lake Trinidad

As of 6/2/2021, park staff reports boaters are catching trout on jigs and trolling. There are some walleye being caught in deeper water using jigs. The bass fishing has reportedly picked up over the last couple of weeks. The South shore has produced good size trout regularly using PowerBait, doughballs, and nightcrawlers. Call the park for the most up-to-date conditions at 719-846-6951.  
Lake Trinidad

Arkansas River - Buena Vista to Salida

As of 6/2/2021, Braden Baker with Ark Anglers writes, "The Arkansas River is still fishable despite being well into our historic runoff timeframe. Clarity has improved to around 3 feet of visibility following cool, overcast days and the river is very fishable today. This is a temporary lull in flows that will exit with the forecasted warmth and sun in the next 10 days, but in the very short term, the river is offering good conditions to those that are in the valley this week. Anglers can find success by focusing their efforts on the slow velocity shelters in the river, where fish will migrate to avoid the faster current. While the river is stained, consider fishing high contrast flies like Prince Nymphs or rubberlegs stoneflies in tandem with caddis pupa or baetis nymphs. Golden stonefly and yellow sally nymphs should also be in your arsenal as droppers while we have a bit of clarity. Streamers can also work well in the stained water, as mature trout take advantage of the conditions to ambush juvenile browns. While you still want to cover a fair amount of water, it can pay off to be more methodical and deliberate in your approach, spending a little more time in likely water and making a few more drifts than you would if the water clarity was better. It's hard to say how long conditions will remain marginally fishable, as we have many sunny and 80 degree days on the near horizon. We may continue to see a stair-step pattern of rising flows and plateaus that give us brief windows of opportunity as flows rise. Make the most of the conditions while they last!" Flows: 759 CFS at Hecla Junction (6/4/2021) http://www.arkanglers.com/

Vega Reservoir

Park staff reports as of 6/1/2021, The Island boat ramp is open at this time. Inspection hours are from 7:00 a.m. - 8:30 p.m. daily. Fishing has slowed down a bit, however, anglers are reporting catching some nice rainbows in 16 - 20 inch range using silver spinners, PowerBait and worms. Lake levels are below normal. In order to prevent boats from launching during hours that ANS inspections are not available, the park has installed new gates and one-way spike strips. The spike strips will allow boats to exit the lake after hours at the Island boat ramp but will prevent anyone from entering the lake during non-inspection hours. Boaters that plan to exit the lake after inspection hours should park and use the Island boat ramp so that they are not behind locked gates after hours. The south road and the gravel pit area are open for the season. The Visitor Center is open from 8:00 a.m. to 4:00 p.m. daily.

Lake John

Grand Lake

As of 6/4/2021, Fishing with Bernie Guide, Sam Hochevar reports, "Water temp is 44 - 47, and both inlets are flowing. Rainbows and browns have been biting well at the surface early in the morning and throughout the day on overcast days. By mid-morning on sunny days try fishing a little bit deeper in 10 to 15 feet of water. Lake trout are spread out in the water column, with most being caught in 30 - 50 feet of water on small plastics tipped with sucker meat." https://www.fishingwithbernie.com
Grand Lake

Lake Granby

As of 6/4/2021, Fishing with Bernie Guide, Dan Shannon reports, "Water temp has been 48-53 degrees. The bite has slowed a bit but is still good. Rainbows and browns are biting well in the inlets and rocky shorelines on spinners, and small natural colored crankbaits. Lake trout are being caught in 20-60ft of water, the transition areas between the rocks and mud have been good areas to concentrate on. Small tubes, grubs and crayfish imitations have been most consistent with color being different every day. Tip your jig with a small piece of sucker meat and keep it fresh for the best action." https://www.fishingwithbernie.com/
Lake Granby

Williams Fork Reservoir

As of 6/4/2021, Fishing with Bernie Guide, Randy H reports, "Ramp hours are 6 am to 8 pm. Williams Fork is at 73% water capacity. The Lake is 19 feet low. Surface temp is 49 early morning warming to 52 by afternoon. The Lake Trout bite is slow to fair. Juvenile lakers are biting well in 60 to 70 feet of water on small plastics tipped with sucker meat. Mature fish can be found in 40 to 70 feet, but the bite is tough right now. I'm seeing trophy-class lakers break the surface, casting for them is hit and miss. Northern Pike are sluggish in the cold water and recovering from the spring spawn. Kokanee fishing is slow due to lack of population." https://www.fishingwithbernie.com/
Williams Fork Reservoir

Conditions Report - Southwest Colorado

Jackson Gulch Reservoir

As of 5/7/2021, the staff at Mancos State Park report, "Most of the fishing right now has been happening from the bank with typical baits: rainbow or green PowerBait, worms, and 'crawlers. A double-hook rig with PowerBait on one hook and a worm on the other will open up your odds of both trout and yellow perch. Fishing has been good for 10-12-inch trout and small yellow perch. A few splake (brooke trout/lake trout crosses) have been caught using the same baits or small lures. In-line spinners (Mepps, Panther Martins) are working. Let the spinner sink for a count of five or six, then reel mid-speed (enough to get the blade turning but not too fast). Trout should start surfacing in the still mornings and evenings, making for good action with the fly rod, especially from a float tube or kayak."
Jackson Gulch Reservoir

Blue Mesa Reservoir

As of 6/4/2021, anglers have reported success fishing 10-20 feet of water for trout and heading deeper to 50-80 feet of water for lake trout. The Blue Mesa Lake Trout tournament continues through July! The Lake Fork and Elk Creek boat ramps are open and have hours 6 a.m. to 8 p.m.
