Eleven Mile Reservoir

As of 7/16/2021, The 11 Mile Marina reports "Trout fishing is very good. Action continues with trolling, jigging, casting and more. Bite times can vary we like mid-morning but early risers are doing well. Many fish are suspended 20 to 35 feet deep no matter where you go. West End has lots of action for Cuttbows running 13 to 15 inches. Kokanee fishing is fair. Go out from North Shore in 60 feet of water 35 feet down. There are some really little ones turning up which is good news for the future. Northern pike fishing is good. The water temp is perfect for spinner baits. They tend to work better when the water hits 66. Try Bill's Spinner Bait in Black/Blue, Orange/Brown or White. Work them like a jig. West end is good. We like coves from Howbert to Witchers. Later in the afternoon is good. Jigging and pitching are working." https://www.11milesports.com/fishing-report

Arkansas River - Leadville to Buena Vista

As of 7/29/2021, Braden Baker with Ark Anglers writes, "The river north of Buena Vista offers the best wade fishing conditions on the river, particularly above the Lake Creek confluence in Hayden Meadows but even the river in Granite is now very approachable. We've also have good reports from the pocket water sections north of Buena Vista through the tunnels, Railroad Bridge, and Numbers. Be prepared for yellow sallies, golden stoneflies, brachycentrus caddis, and pale morning duns above Buena Vista. Some green and gray drakes are also hatching in Hayden Meadows, yielding even better dry fly opportunities on the upper river. Guides and DIY anglers are reporting very good dry and dry-dropper fishing this week, but nymphing through the deeper pools and pockets will also be effective." Flows: 169 CFS at Hayden Meadows, 475 CFS at Granite (7/29/2021) http://www.arkanglers.com/

Lake Trinidad

Arkansas River - Buena Vista to Salida

As of 7/29/2021, Braden Baker with Ark Anglers writes, "With clarity back on most of the river, the fishing has really picked back up this week. Flows are now being augmented for recreational levels and we anticipate the river remaining about this flow for the next several weeks. Flows are great for floating but the edges are getting more and more workable for wade fisherman. Expect fish to hold in velocity shelters along the banks, in mid-stream pocket water, or slower runs near drop-offs where food is carried to them without their having to expend much energy. Fresh golden stonefly shucks are on the rocks above the water most mornings, and we are still seeing some late yellow sally activity. This has given us some fun action on larger attractor dry flies. Caddis and pale morning duns make up the smaller food items, with sporadic midge and trico hatches taking the microscopic award. Dry dropper and shallow nymphing tactics are generally the most productive, but streamer fishing has been very effective lately, as well. At times fish are incredibly surface-oriented, yielding windows of great dry and double-dry fly fishing. There are lots of pale morning dun nymphs in the system and hatches mid-day into the afternoon, especially on cloudier days. The next few weeks should provide some of the best fishing of the whole summer! Following a low water spring and an underwhelming runoff, fish are healthy and have fared well through the high water." Flows: 751 CFS at Hecla Junction (7/29/2021) http://www.arkanglers.com/
Arkansas River - Buena Vista to Salida

Vega Reservoir

Park staff reports as of 7/30/2021, The Island boat ramp is open at this time. Inspection hours are from 7:00 a.m. - 8:30 p.m. daily. NOTICE: The Island boat ramp will close for the season at 8:30 p.m. on Thursday, July 29th due to extreme low water levels. Fishing has slowed down a bit, however, anglers are reporting catching some nice rainbows in 16 - 20 inch range using silver spinners. 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.  
Vega Reservoir

Lake John

Grand Lake

As of 7/30/2021, Fishing with Bernie Guide, Jake Foos reports, "The water temp has officially become the most important factor regarding success for all species on Grand Lake as of late. The pleasure boaters, personal watercraft and rentals have taken over but that does not mean that there is still a great bite to be had, pending Anglers look in the right places and at the right time. The lake trout are definitely spreading out on very deep structure and in some cases, finding the thermocline that best fits them to get through the "Dog Days" of summer. Right now, it takes a lot of moving around and paying special attention to your electronics for maximum success. We have started downsizing our presentations for numbers of bites throughout the day to maximize action. Most of our fish are coming from the 80' deep range with multiple bites coming suspended over deep water. The good thing about finding suspended fish is that they are very hungry and willing to take a jig. Small jigs like twisters and grubs have been getting all of the action when tipped with a piece of sucker meat. Rainbows and browns continue to produce a steady bite but that means that you have to fish very early in the day. Surface temps are at the highest you will find and these fish go deeper as soon as the sun hits the surface. The best lures for these fish have been a small Leech Flutter Spoon from CLAM Outdoors as well as a drop kick jig that is tipped with a small crawler and is suspended below a slip bobber. https://www.fishingwithbernie.com
Grand Lake

Lake Granby

As of 7/2/2021, Fishing with Bernie Guide, Dan Shannon reports, "Fishing remains fair to good for all species. Best bite has been in the morning before the storms roll in. Kokanee are being found 20-30' deep suspended over deep water along Knight Ridge and mouth of Grand Bay. Rainbow trout and Brown trout are being caught along the shorelines, focus on areas where creeks are flowing in and transition areas where rocks meet mud. Small spoons and deep diving crankbaits have been working well cast from shore or trolled. Lake trout have continued to move deeper as the water warms and are being caught in 60-90ft of water. Bright colored and glow tubes and grubs tipped with a small piece of sucker worked right on the bottom has been most productive baits." https://www.fishingwithbernie.com/
Lake Granby

Williams Fork Reservoir

As of 7/30/2021, Fishing with Bernie Guide, Randy H reports, "Ramp hours are 6 a.m. to 8 p.m. Water capacity is at 89% and dropping. Inflow is 122 CFS, outflow is 196 CFS, the lake is 7 feet low. Visibility is about 12 feet. Surface temp is 66 early morning warming to near mid 70's in the main body on sunny days. The shallow bays are abnormally warm. The lake trout bite is fair (single-digit catches per rod). The best bite is early morning, once the sun is high the bite slows until late afternoon. Look for lake trout in 60 to 90 feet of water. Tubes or other plastics tipped with sucker meat fished on the bottom are working best. Due to CPW not stocking Rainbows or Kokes in an effort to rid the lake of gill lice, fishing for both species is slow. Northern's are also slow, but I'm seeing a little activity early AM and late PM on lures worked with a slow to medium retrieve." https://www.fishingwithbernie.com/
Williams Fork Reservoir

Mack Mesa Reservoir

After months of hard work, Mack Mesa Reservoir is now refilled and has been restocked with bluegill to start developing a forage base for the largemouth bass and other species to be stocked later this summer. Those warm water species include largemouth bass, black crappie, bluegill, and channel catfish. CPW also plans to stock trout in time for the fall and ice fishing seasons.

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 7/30/2021, The Blue Mesa Lake Trout tournament continues through the last day of July! The Lake Fork and Elk Creek boat ramps are open and have hours 6 a.m. to 8 p.m.

San Juan River

Animas River at Durango

As of 7/28/2021, Duranglers reports, "We have seen a lot of rain the past few weeks and it's caused some big flow bumps and clarity issues. This is indeed impacted the fishing currently, but more water means decreased water temps and better fishing into the late summer! Hopper season has arrived so a hopper/dropper is key." Flows: 805 CFS at Durango (7/28/2021) Duranglers.com 
Animas River

Dolores River - above McPhee Reservoir

As of 7/28/2021 Duranglers reports, "The upper Dolores drainage is fishing solid. Dry dropper all day every day. Watch for hatches of caddis, PMDs, and moths." Flows: 306 at Dolores (7/28/2021) https://duranglers.com/

Gunnison River

As of 7/28/2021 Duranglers reports, "If you want to catch more fish, put on the nymph rig and fish deep with weight. If you want to catch fish like a well-adjusted person who isn't all about numbers and actually likes to have fun, fish a dry. PMDs, Caddis, and some Yellow Sallies are out and about. Fish a dry/dropper for the best of both worlds." Flows: 660 CFS below Gunnison Tunnel (7/28/2021) Duranglers.com
