Eleven Mile Reservoir

As of 9/10/2021, The 11 Mile Marina reports "Trout fishing is fair to good. The bite can be hit and miss but there sure are a lot of very nice fish being caught in the 18" to 24" class. A variety of baits are working depending on how you like to fish. Pop Gear crowd doing very well with Arnies Pop Gear or Green Rainbow by Lure Jensen. Tube jigs are coming on. Kastmasters, Tas Devils and Krocodiles are also hot. The West End gets a lot of attention but we are catching fish all over the lake. Sometimes the North Shore Marina kicks out fish as good as anywhere. Don't overlook the East End for bigger fish. Less pressure bigger fish. Shore anglers doing well at sundown and at night. Kokanee fishing is poor. No good news to report other than one here one there. The story of this past Summer? We are still working the sling blades and dodgers with a variety of offerings. You will catch Trout in the process. Northern pike fishing is good to very good. A lot of nice fish in the 28" to 33" range being caught. We have had action all around the lake. Bill's Spinner Baits, White or Chartreuse tubes, Rapala and spoons are all seeing decent action. Bite times have been spread throughout the day with mid-morning and late afternoon showing off. Bigger fish are showing their face and even taking swipes now. Opportunities are increasing for a trophy fish. Crawfishing is excellent. It's prime time of the Season if you like crawfish. We sell some awesome traps that will fill up and make you happy with a big boil of deliciousness. The peak season is now through early September. Stop in we will show you how we do it." https://www.11milesports.com/fishing-report

St. Vrain State Park

As of 9/24/2021, pike and walleye/saugeye will also chase larger swimbaits and spoons, but we recommend suspending only a few feet down, as most ponds with Pike are very shallow at St. Vrain. Pike and Walleye will also chase streamers and poppers, but will usually require some form of a leader to prevent breaking free.

Conditions Report - Southeast Colorado

Arkansas River - Leadville to Buena Vista

As of 9/22/2021, Braden Baker with Ark Anglers writes, "The upper Arkansas is in great shape and with a much cooler forecast in the next couple of weeks our northern fish will have a very comfortable environment as we head into the fall. Hayden Meadows is still the most wadeable section of the Arkansas, though now that the Voluntary Flow Management Program has ended more of the river below the Lake Creek confluence will offer easier wading access. The low, clear flows in Hayden Meadows can make for more technical fishing and spookier fish, so be very thoughtful in your approach. Nighttime cold may make for slow mornings near Leadville, but mid-day and afternoon is still fishing well this far north. This area is seeing a fair amount of pressure, so be very courteous to fellow anglers and try to give your neighbors plenty of their own room to fish. We are seeing blue-winged olives and pseudocloeons above BV, so be prepared with small baetis nymphs, emergers, and dries in #20 on average, sometimes smaller. For larger food, be prepared with caddis, grasshoppers, and golden stoneflies above Buena Vista. 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. Streamers can also be a great way to probe some of the deeper pockets north of Buena Vista." Flows: 65 CFS at Hayden Meadows, 109 CFS at Granite (9/22/2021) http://www.arkanglers.com/

As of 9/24/2021, park staff reports the lake is at 732 surface acres with a surface elevation of 6184.74, and the water level is decreasing. The surface water temperature is around 65-68 degrees. Islands have appeared and some hazards may not be marked. Boaters have had luck trolling worm harness, and jigging walleye/bass off of structure. Perch, trout and walleye are abundant. South shore has produced good size trout very regularly using PowerBait, doughballs and nightcrawlers. Boat inspection hours are 7 a.m. to 7 p.m. Call the park for the most up-to-date conditions at 719-846-6951.

Arkansas River - Buena Vista to Salida

As of 9/22/2021, Braden Baker with Ark Anglers writes, "The Voluntary Flow Management Program has ended and the river has dropped back down to native flows. This adjustment has brought the river back into the ideal flow range for our local trout (240-400 cfs at the Wellsville gauge) and they will be able to maximize their use of the river to their benefit. We will still have just enough water to float fish the Arkansas near and below Salida but this adjustment is definitely welcome news to wade anglers who will have more flexibility on wadeable water the rest of the summer. The weather is slowly cooling down with lows in the 30s and 40s and highs in the 70s in the middle basin this week. These air temperatures are helping moderate water temperatures and are giving us good conditions throughout the day to fish. At current water levels be prepared for spookier fish! A quiet, thoughtful approach will pay big dividends with the lower water. Clarity is excellent in the middle basin and flows have receded now that we are back to sunny, dry weather. With flows dropping to native levels, expect fish to be able to occupy more of the river rather than just the edges like they do during high summer flows. Fresh golden stonefly shucks are on the rocks above the water most mornings, and the presence of these insects alongside grasshoppers has given us some fun action on larger attractor dry flies. Blue-winged olives and pseudocloeons are hatching in the middle basin, so small baetis nymphs, emergers and dry flies should be in your arsenal (#20 on average). Caddis and red quills make up medium-sized 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. The next few weeks should provide some excellent early fall opportunities. On the warmest days, fish will be looking for oxygen so if you can find aerated water you'll find trout. Following a low water spring and an underwhelming runoff, fish are healthy and have fared well through the high water of summer." Flows: 227 CFS at Hecla Junction (9/22/2021) http://www.arkanglers.com/

John Martin Reservoir

As of 9/24/2021, WEST BOAT RAMP is CLOSED due to low water levels. EAST BOAT RAMP remains open and available to launch vessels. The East Boat Ramp was designed as a low-water boat ramp. Larger vessels with deep hulls, or a trailer that sits high above the ground, will find it difficult to impossible to launch. Most vehicles will have to be partially submerged to launch boats from trailers.

Grand Lake

As of 9/10/2021, Fishing with Bernie Guide Dan Shannon reports, "Ramp hours are 6 a.m - 6 p.m. Water temps continue to cool and less traffic on the water has helped the bite. Fishing has been fair to good for all species. Rainbow trout and Brown trout bites have been good, fish along shorelines and docks with erratic retrieve of spoon or crankbait, color does not matter but make sure to pay attention on the pause of the lure. Lake trout are being caught in 50-70' of water, look for them with your electronics then fish on the bottom with small jigs and plastics tipped with sucker, glow colors have been best producers." https://www.fishingwithbernie.com
Grand Lake

Lake Granby

As of 9/10/2021, Fishing with Bernie Guide, Dan Shannon reports, "Ramp hours are 6 a.m. - 6 p.m. Cooling water means the bite is picking up! Lake trout have moved to pre-spawn locations in 50-70' of water. Small minnow imitations on a jig head tipped with a small piece of sucker has been go-to lure, chartreuse or orange colors. Rainbow trout and Brown trout are active and moving shallower, target these fish by trolling spoons and cranks in 12' of water along shorelines or casting crankbaits and tubes along rocks and transition areas. Great time of the year to be on the water, the elk are talking along the shore of RMNP and fishing is getting better by the day!" https://www.fishingwithbernie.com/
Lake Granby

Williams Fork Reservoir

As of 9/10/2021, Fishing with Bernie Guide, Randy H reports, "The new ramp hours are 7 AM to 7 PM. Water capacity is 75%. Inflow is 31 CFS, outflow is 275 CFS. The lake is 17 feet low. Surface temp is 63 early AM warming to mid 60's. This will be my final fishing report for the season. The boat ramp will be closed by September 12th or sooner due to the low water level. The Lake Trout bite is slow to fair the first half of the day. The fish are up and moving around in the AM but by noon most of them are belly down on the bottom. Look for them in 70 to 100 feet of water. Tubes or small grubs tipped with sucker meat worked slowly on the bottom is working best. Keep your bait moving or a crawdad will get it. Northern Pike are slow but catchable if you're very persistent. Early AM and late PM is the best time to fish. Crankbaits, jerk baits or swimbaits fished with an erratic slow to medium retrieve may get hit. Shore fishing for Rainbows is slow due to low population, but as the water continues to cool large resident Rainbows will be feeding along the shoreline. Kokanee trolling is very slow as CPW has not stocked the lake since 2019 in an effort to rid the Kokes of gill lice" https://www.fishingwithbernie.com/
Williams Fork Reservoir

Mack Mesa Reservoir

Mack Mesa Reservoir is 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.
