Arkansas River - Leadville to Buena Vista

Information provided by Braden Baker with Ark Anglers. As of 7/1/2020, Braden writes that “we've got excellent conditions right now on the upper Arkansas. Buena Vista and north offers the best clarity on the whole river right now. The Hayden Meadows area is the most approachable section to wade fish, but if anglers are comfortable rock hopping through BV and the Numbers, good pocket water is starting to open up along the edges. Expect to see some early season yellow sally, golden stonefly and caddis activity. Over the weekend we saw some hatching pale morning duns, so smaller mayfly nymphs, emergers and dry flies would be good to have in your arsenal. Even if nothing is hatching, you'll likely find opportunistic, competitive fish taking refuge in velocity shelters looking for an easy meal. Think dry-dropper or shallow nymphing with large attractor flies like chernobyl ants, stimulators, Pat's rubberlegs, etc. As the water continues to recede, conditions will get better and better!” Flows: 286 CFS at Hayden Meadows, 768 CFS at Granite (6/29/2020) http://www.arkanglers.com/

Expect long lines at the entrance to the park, to launch your boat and to find a parking space. Be prepared to walk a distance from your parking spot.

Crappie and bass fishing on Horseshoe has been more productive than on Martin, with most anglers stating that artificial lures, jigs, and spinners result in the most takes. Warmer waters have led to increased activity from catfish and carp. Fishing for catfish has been reported as being the most active around dawn and dusk.”

Wiper have been most active in the early morning hours prior to sunrise.”

Arkansas River - Buena Vista to Salida

Information provided by Braden Baker with Ark Anglers. As of 7/1/2020, “conditions are great in the middle basin with flows hovering just below 1,000 cfs. Anglers will find the best success by fishing hard right along the banks, where they will find fish aggressive and looking for an easy meal. Currently, you'll want to focus on fishing the soft pockets of slower water along the edges. We've had some great reports from intrepid anglers working the edges with large attractor dry/dropper setups, and flies that imitate grasshoppers and stoneflies are usually the ticket. Golden stones and yellow sallies are the key food items here, and a mix of caddis are active as well. We are seeing lots of active pale morning dun nymphs mid-day, so expect to see adults on the water in the next couple weeks. With peak runoff behind us, now is the time to plan for your summer on the Arkansas!” Flows: 963 CFS at Helca Junction (6/29/2020) http://www.arkanglers.com/

Williams Fork Reservoir

As of 6/28/2020, Randy, a guide with Fishing with Bernie, reports that “the lake is finally full. Water capacity is at 100%. Surface temp has risen to 59 warming to 62 on a sunny day. The Lake trout bite has picked up now that the lake has topped off. All age groups can be found in 55' to 85'. Fish deeper as the day wears on. Tubes and rubber grubs tipped with sucker meat can produce limits for the patient angler. Some rainbows are being caught lake wide by bottom fishing with worms, eggs or PowerBait. Small rainbows are hitting spinners and flies in the inlet. Northern pike are slow but devoted fishermen are catching a few in the west side bays. Due to lack of population, Kokanee trolling is slow with most angler's reeling in young lake trout. Ramp hours are 6AM to 8PM.” https://www.fishingwithbernie.com/weekly-fishing-reports 
Williams Fork Reservoir

Grand Lake

As of 6/28/2020, Fishing With Bernie guide Sam Hochevar writes: “the water temperature at Grand Lake is 61 degrees in the mornings. Lake trout fishing has been good in 20 to 45 feet of water. Small spoons and tubes tipped with sucker meat has produced most of the lakers. Rainbows and browns have moved a little deeper and are being caught in 15 to 20 feet of water during the day. Trolling has been the most effective technique targeting the browns and rainbows.” https://www.fishingwithbernie.com/weekly-fishing-reports 
Grand Lake

Lake Granby

As of 6/28/2020, local angler, Dimitri Georges, reported the following conditions at Lake Granby: “Lake trout are concentrated on the side slopes of mid lake troughs (deep water channels), but are generally preferring the sub 50 deg F water which is found at 60 feet deep. Lakers were stuffed with Mysis shrimp and nothing else. Lakers sitting on the bottom are not feeding, only suspended fish in the 18” class are actively feeding all day, but especially early morning and right at dusk.” Dimitri recommends anglers consider the following lures: UV pink hoochies (squid like lures) with smile blades, pink or black and white wedding rings with smile blades, and humdinger spoons in green/orange/dotted coloration behind small Colorado blades.

North Delaney is producing the largest measurements but fish activity is slower than the other two. Rapala’s, tub jigs, leeches, chironomids, damsels, scuds, and nymphs 10 to 20 feet under an indicator has been best during the day, stripping crayfish and leeches has been successful at night and twilight hours.”

Blue Mesa Reservoir

As of 5/25/2020, the folks at Blue Mesa Fishing report that “the fishing on Blue Mesa has been excellent for all species! We are still seeing some good casting opportunities for rainbow and brown trout, excellent trolling for rainbow trout with plenty of salmon action mixed in (they are big!) and some GIANT lake trout! Blue Mesa has been open for 10 days now and the fishing has been equally good all across the lake.” Specifically, anglers can find trout by “casting the rocky shorelines, especially early and late in the day. The number of rainbow trout appears to be very good as trolling for them in the top 15 feet of the water column has been excellent most days and a lot of times they are getting to your presentation faster than the kokanee salmon!” For Kokanee, anglers should focus on the top of the water column, Blue Mesa Fishing reports that “they seem to be holding in the top 30 feet of the water column most days and so far they are a lot spunkier than they were last year, which is an encouraging sign that the gill lice aren’t hitting them so hard they appear lethargic! One thing that we have been impressed with is the size of the kokanee for this time of year; there are some really nice fish showing up!” bluemesafishing.com

Ridgway Reservoir

Anglers have been able to catch trout in the reservoir using typical bait and tackle, worms and spinners. Below the dam, on the Uncompahgre River, there have been few hatches so fly anglers have been the most successful with small nymphs sizes 22-24 in colors black and red.

Gunnison River

As of 7/1/2020, lower water levels and increased insect activity currently makes a dry fly and dropper set up perfect for fishing on the Gunnison. Streamflow was measured near the town of Gunnison at 613 CFS (as of 7/1/2020). Current discharge levels are well below normal levels for this time of the year. Since peak runoff at the beginning of June the Gunnison River has consistently measured well below normal levels of discharge.

Conditions Report - Statewide

Statewide

Summer fishing is here. Rivers and streams are sliding down from their peak spring runoffs and the hatches are on in most parts of the state. For fly anglers, this is the time for the infamous dry dropper combination set up. There are increasing reports of yellow sally, caddis, golden stones, PMD’s, and even some hoppers being eaten off the top. There is also good fishing in many lakes across the state as well, especially for warm water fishing. However, there have been some reports that indicate the bite has slowed for certain water bodies that have reach temperatures too high for good fish activity, at least throughout the daytime. If that is the case for your local fishing hole, head into the mountains to find lakes and reservoirs with less heat and cool, deep depths.
