Conditions Report - Statewide

Rivers and Creeks

With the warm dry conditions we have been experiencing this year the rivers and creeks across the state are experiencing much lower flows and higher water temperatures than normal. Fishing for trout should be focused to the coolest parts of the day, fishing early in the morning when the water temperatures are cooler from overnight is recommended. Nymphs and emergers have been productive patterns throughout the state. For the dry fly fisherman mid-summer means terrestrials! Ants, hoppers, and beetles have been consistently producing fish. Keep in mind that when water temperatures rise near 70 degrees trout are at their most vulnerable, it is important to play and land the fish as quickly as possible and waste no time removing the hook and returning the fish to the water. Looking forward to fall we have multiple fall spawning fish that will become active shortly, keep an eye on future reports for kokanee runs and brown trout spawn reports.

Conditions Report - Southeast Colorado

Arkansas River-Lake Pueblo

As of 7/25/2018 not much has changed on the tailwater in the last few weeks. The river below the dam is running a lot lower than in past years. The flows have been between 250 and 700 cfs. Caddis, midges, and a few blue wing olives have been making up the hatches recently. Streamers and spinners can also be effective. The river is tinted green right now with about 18 inches of clarity. This bodes well, as anglers can use heavier tippet/line during this time as the fish are not as leader shy during the higher flows. 
Lake Pueblo State Park

Trinidad Reservoir

As of 7/30/2018 The lake is at 738 surface acres with a surface elevation of 6185.30. Surface water temps around 72 degrees. Shore fishermen are catching trout on homemade dough bait, PowerBait (green color) and worms all along south shore. Reilly Canyon river has slowed down to a trickle and sandbars starting to emerge around the lake. The most action for fish is occurring in the early mornings and late evenings. Some catfish are being reported around the inlet. Boaters have done well targeting walleye. Smallmouth caught early in the morning and late evening. Trout are caught during all hours. Worm harnesses and crank baits have worked well. Fish are being found around 15-25ft. The shallow water tends to be to warm for fish during the majority of the day, the technique has been to find the deep channels where colder water exists or wait for cooler morning and evening temps. BOATING ALERT: Due to water being released, boaters be aware of underwater hazards. Not all hazards will be marked. 
Trinidad Reservoir

Lake Pueblo

As of 7/25/2018 Surface temperature is 76 degrees. Fishing reports have been fair for bass. Anglers are reporting fair success using soft plastics. Walleye are being caught trolling using bottom bouncers and vertical jigging techniques over the top of structure. Fish are deeper at this time of year, as the water warms up, so anglers should focus on fishing deeper during the day and early and late in the day as well. Boaters are reminded that the boat ramps open at 5 AM and close at 11 PM daily. 
Lake Pueblo

John Martin Reservoir

As of 7/23/2018 due to a low water year throughout the state and the Arkansas River drainage water levels are dropping and the fishing has been tougher. Walleye fishing is slow with water temperatures in the mid 70's. Fishing for white bass and wiper can be good if anglers are able to figure out where the bait that these fish are feeding on is located. Crappie fishing has also slowed drastically as the water temperatures have forced the fish into deeper water.
John Martin Reservoir State Park

Lathrop State Park

As of 7/24/2018 the surface temperature on Martin Lake is around 72 degrees. Visitors have been fishing from shore and on boats. With warming weather, Martin Lake has seen increased boat traffic on the weekends. Trout are not as active and will move to deeper water during the heat of the day. However, fishermen still have success using PowerBait and similar products. One visitor reported catching a 14 inch trout near the Martin inlet. Warm water fish, like bass and sunfish are active in the mornings and may be found guarding spawning beds near the shore this time of year. Several northern pike have been reported. Visitors are using a variety of bait to catch pike including stick bait lures, such as Rapala lures. The surface temperature of Horseshoe Lake is about 69 degrees. Visitors are having some success fishing from the dam for smallmouth. The smallmouth bass start to move around in the morning as the water heats up and have been seen feeding from the surface. Small rubber spider or other top water bait could produce exciting catches during those times.

Blue Mesa Reservoir


As of 7/22/2018 Mancos is a great place for consistent action from trout and yellow perch. Most of the trout action is from 10-12 inch fish, but there's very good opportunity at an 18-20 inch trout and a few 12 inch-plus perch. Great opportunity for kids to catch fish. Most anglers are finding success with bait (PowerBait, eggs, and crawlers) fishing just off bottom or under a slip bobber. For a chance at the yellow perch and trout, a small jig fished under a bobber on a long leader and tipped with a piece of worm is a good bet. Casting or trolling typical in-line spinners (Panther Martins, Mepps) from boats is another approach at the trout. Hand-launchable boats (non-motorized kayaks, canoes, belly boats, etc) are a great way to fish the lake in this off-season. This is the first year in more than 15 years that the lake has not gotten decent ice to fish.Mancos State Park
