 Northeast Colorado

Antero Reservoir - The current water temperature is around 65 degrees. The fish are the most active during early morning and late evening and can be found swimming in the shallows during these times. Spoons and jerk baits are currently the most effective method. Fly anglers are catching fish with nymphs presented near the bottom of the reservoir.

Barr Lake - The current water temperature is around 72 degrees. The reservoir water levels have dropped in the past week. Anglers are reporting that the green tint to the water clarity is quickly coming back. The wiper fishing is currently rated as good although they have been smaller in size. The walleye fishing has slowed down. The lake becomes very busy on the weekend, so expect to see plenty of kayaks and paddle boards on the water.

Clear Creek - The creek is currently flowing at 650 cfs near Golden. The trout fishing is rated as good with the dropping flows and clear water. Anglers are having the most success nymph fishing deep holes and the edges of the creek. Soft hackle pheasant tails and caddis emergers are working very well. Spin anglers are having success using jigs in the pockets and deep holes. The water is very clear, so approach the fish with caution to avoid spooking them. Some anglers are catching fish on dry flies, but nymph fishing is more effective at this time.

Dream Stream - Flows are considerably lower than normal for this time of year. The City of Aurora expects Spinney Reservoir to fill sometime in July. Currently the fishing is pretty good considering the low flows. Effective patterns include #18 Mercury Flashback Pheasant Tails, #18 Buckskins, caddis larva, #18 Barr's Emerger #16 Barr's Graphic Caddis. #16 Elk Hair Caddis, #14-16 yellow Stimulators, #16 Mathew's Sparkle Dun (PMD), #10 Amy's Ant, and #24 Stalcup's Trico are fooling trout on the surface. Crowds have been moderate to heavy, so plan accordingly.

Eleven Mile Reservoir - The ferocious bite has cooled, but action is steady and consistent. Bite times are more specific than they have been. Water quality issues have a real effect. If you are dragging a weed you are definitely not going to catch a fish. Check your line frequently if trolling. The bite has been early and most of the fish stop biting by 10:00 a.m. Kastmasters and Tasmanian Devils are always consistent. Use a night crawler and float it with a marshmallow after the sun sets. The kokanee salmon action is very sporadic. The fish are biting early in the day. The fish are holding near the bottom, so use a downrigger or a lead core. Vertical jig if conditions allow.

Fern Lake RMNP - The greenback cutthroat trout fishing is currently rated as excellent. There are plenty of fish feeding on the surface and anglers are catching them on small Elk Hair Caddis and Parachute Adamís dry flies. Small streamers are also effective for anglers using a sink tip fly line. The fish are congregating near the inlet, but the fishing is excellent at any location on the lake.

Spinney Mountain Reservoir - The northern pike action is hot right now. The fish are biting Rapalas, Zonkers, Daredevls, and Tazmanian Devils. The trout are hitting on almost anything for both spin and fly anglers.

Southeast Colorado

Arkansas River Headwaters - The upper river is in excellent shape and improving by the day. Water flows have risen due to rain this week and an increased release from both Twin Lakes and Clear Creek Reservoir, but conditions are still within the ideal range for the wade fisherman. Visibility is good on the upper river. We are already seeing good caddis and golden stonefly activity mixed with drakes through Hayden Meadows down to Granite.

Clear Creek Reservoir

The current water temperature is around 63 degrees. The trout fishing from boat and shore has been fair at Clear Creek
Reservoir. A majority of the boat and shore anglers are catching groups of 8 to 12 inch rainbow trout. Shore fishing access at the boat ramp parking area is still limited because of both high water levels and willows right at the shoreline. Shore anglers may want to consider wearing hip boots or chest waders to fish the shoreline more effectively. PowerBait and salmon eggs fished off the bottom has been productive for shore anglers.

Successful trout anglers trolled the southern part of the reservoir with bullfrog colored Tasmanian Devil lures (1/4 oz). A few boat anglers caught tiger musky by fishing underwater structures with Rapalas. The best kokanee salmon fishing has been in the morning. A squid tipped with white corn is one of the best methods to land kokanee salmon at the eastern part of the reservoir.

Lake Pueblo - The current water temperature is around 73 degrees and the water is clear with a visibility around 8 feet in depth. Anglers are reporting seeing more algae growth and are frequently pulling in weeds off the bottom. Worms are working well in 20 feet of water on jigs. Use a slow retrieve if you are not getting many bites. Be cautious of weekend recreational activity if you plan on using a boat.

Monument Lake - The lake is currently full and the fishing is rated as good. The perch and bluegill are biting very well on almost anything you throw at them. Anglers are catching pan fish and bass using worms under a bobber. The trout fishing is slow during the day, but anglers are having a lot of luck catching trout during the last hour of daylight. Look for the trout to be swimming the shoreline and feeding on the surface.

North Gateway Park - A rise in temperatures has caused the trout fishing to slow down significantly. Anglers are having luck catching saugeye, bass, catfish, and crappie. The crappie are averaging very small in size.

Skaguay Reservoir - Anglers are reporting good trout fishing as of recently. The rainbow trout are actively biting green and brown wooly buggers - off the shoreline. A majority of the rainbow trout being caught are in the 12 to 14 inch range. Some fish are rising to feed on the surface. Big dry flies and hopper-dropper rigs are becoming more effective as the water temperatures rise.

Trinidad Lake - The fishing from the south shore has been slow as of recently. Anglers are catching fish using worms and PowerBait. The fishing near Reilly Canyon has slowed down and we have not received any reports of anglers catching catfish at this time. Yellow perch are being caught around the lake near flooded vegetation. Boat anglers have been catching mostly trout and a few walleye. Worm harnesses and trolling have been the most effective methods for boat anglers.

Northwest Colorado

State Forest State Park

North Michigan Reservoir is fishing very well for rainbow trout and cutthroat trout. Anglers are having the most success
using PowerBait. The rainbow trout are biting very well at Ranger Lakes on PowerBait and salmon eggs. Worms are also
working well. We have not received any reports from Lake Agnes this week.

Steamboat Lake

Fishing has been slowing down all over the lake. Boat, shore, and stream anglers are all reporting some action but overall
slow fishing. PowerBait has been doing well from shore and Kastmasters have been working for the boat anglers. Early
morning or later evening is the best time to fish.

Southwest Colorado

Blue Mesa Reservoir - The current water temperature is around 65 degrees. Anglers are reporting that the fishing is good, especially in the morning before 11:00 a.m. Boat anglers using down riggers are having the most success catching trout and kokanee salmon. Pink, green, and orange Arnies are working very well. Shore anglers are having luck using jerk baits and Gulp minnows.

Navajo Reservoir - The current water temperature at Two Rivers Marina is around 75 degrees. The fishing has been excellent as of recently. Anglers are catching a lot of smallmouth bass and northern pike near the shallow bays. Crank baits are the most effective method for catching bass right now and the northern pike are biting slightly bigger lures imitating bait fish.


Rivers and Creeks

Summer fishing conditions have arrived and anglers are taking full advantage of the manageable water flows. It is officially
dry fly season and the fish are actively feeding on the surface. It is also mosquito and horsefly season, so do not forget your
bug spray. Large dry flies such as Elk Hair Caddis, Yellow Sallies, and Renegades are working well throughout the state.

The fish are still biting on large nymphs such as San Juan Worms, Stoneflies, and Prince Nymphs, but be prepared to transition into smaller nymphs once the water temperatures rise. Anglers should start using smaller leaders and tippets since the
water clarity will continue to improve into autumn. Rainfall will be the only factor that changes water conditions throughout the summer. As summer continues, it is important to focus on fishing during early mornings and late evenings, since the fish will become lethargic during the heat of the day.
