Conditions Report - Statewide

Rivers and Creeks

Although we are approaching the spring season, we are still seeing low flows and clear waters. This means anglers must be more careful not to spook the fish when approaching the water. The spawn beds from the browns are still active, so be cautious of redds when wading along the rivers. There are still waters that are iced over, so anglers will have to primarily rely on tailwaters--the waters below dams or other structures that regulates water flow. The regulated water flow keeps the spots from freezing over and provides warmth for the cold-blooded trout. Even with the warmer conditions of these waters, the fish will still behave sluggishly. Fish diets in the winter are made up primarily of midges and an assortment of small blue-winged olive nymphs and are occasionally supplemented by larger mayflies, annelids, trout eggs, stoneflies, and even caddis larva. Winter fishing typically consists of a lot of nymph fishing since the trout are not overly active due to the cold water temperatures, so try using stonefly nymphs and imitation midges. Remember that the hatches are much smaller in the winter, so keep your flies in the #16 to #20 range. It is also important to be mindful of your split shot usage. With the fish being sluggish, they aren’t going to divert too much energy for food, so making sure those flies drift directly in their path is important. Be sure not to use too much split shot though because the last thing you’ll want to do is to have to retrieve a snag in those cold waters. As the trout continue to get a later start, anglers should mirror that and look for ideal times to be from 11 a.m. to 5 p.m.

Arkansas River

March 27th - Upper River: The cold nights on the upper river will make fishing the upper Arkansas very difficult this time of year. It has iced up a lot above the Twin Lakes confluence, and can be challenging to effectively fish, if you can even find any active fish in the limited open water. Better conditions will be found further to the south below Buena Vista and near Salida throughout the winter. March 27th- Middle River: With blue wings starting to emerge below Salida, we should begin seeing mayflies on the water above town any day now. With any cloud cover this week, be prepared for a blue wing hatch in the afternoon with duns and emergers in #16-18! The river is all clear between BV and Salida, and though fishing has been most consistent down near Salida, we've had a good reports from the BV area as well. Nymphing is still key here, with morning stonefly molts, caddis larva and midge drifts getting fish moving around before lunch. Afternoons have brought more blue winged olive nymphs onto the menu, as the nymphs drift in a daily fashion. Fish will not be far from deep runs and pools, and will likely be concentrated together in the best winter lies. Midges are usually the most plentiful food items available on these colder days, but fish will give larger food a look if it drifts into them. Stonefly nymphs and other attractors like hare's ears, prince nymphs, and pheasant tails are all effective as larger offerings. March 27th - Below Salida: Spring blue winged olives are finally here! For those waiting out the winter (if you can call this a winter) to finally fish dry flies, the wait is over. Trips this weekend and Monday reported good blue winged olive hatches below Salida. Guides are reporting blue winged olive duns on the water in the afternoons as big as #16. Look for Gulper Specials, Parachute Adams, Sprout Baetis, Extended Body BWO's, and Don's BWO in #16-18s to entice fish feeding on top when the mayflies are out. Subsurface mayfly nymphs and emergers can be imitated with Two-bit Hookers, Pheasant Tails, Jujubaetis, Darth Baetis, Bat-wing Emergers, RS2's, etc., also in sizes #16-18. With fish moving into shallower runs, riffles, and edges to intercept drifting baetis nymphs and midge pupa in the afternoons, dry-dropper fishing is becoming more and more effective to match food on or near the surface. Beautiful weather in the forecast this week, with highs in the high 50s and 60s! We've seen consistently strong midge drifts mid-day, with enough bugs on the water that rising fish in the afternoons have been a lot more plentiful. Any more cloud cover this weekend should continue promote some strong blue wing activity, so be prepared with duns and emergers in #16-18! A shallow dry dropper rig in the afternoon can be a great way to find fish picking up emergers in shallower riffles and drop-offs, so don't hesitate to change things up as the day progresses. Underneath, golden stonefly nymphs work well as attractors all day, though molting insects are typically most vulnerable in the mornings. Morning caddis larva drifts round out a diverse buffet for our local fish, so don't hesitate to experiment throughout the day as we are seeing opportunistic feeding at times. Float fishing is challenging at these low flows, but not impossible. Current flows require you to boat right on top of lots of the best holding water, whereas wade fisherman can target the prime lies without disturbing fish. Make sure you are aware of public/private land transitions so you don't end up in a bad spot while fishing.

Lake Pueblo

Lathrop

As of 4/3/2018 the surface temperature on Martin Lake is around 40 degrees. The surface is currently open water, but ice will form on colder nights. Temperatures this winter have not been cold enough to produce ice thick enough to fish on. Use extreme caution before attempting to traverse any newly formed ice. Wear a life jacket and make sure to measure the thickness of the ice every 10-15 feet as you move away from shore. Ice fishing is not recommended. Most fishing is done from shore due to the very windy conditions and rough water we have been experiencing over the last month. Trout have been biting pretty well with some in the 18-23 inch range. Both artificial lures and bait have been successful. Pike have also been active lately with anglers catching a 39 and 42 incher. Spoons and large spinner baits are best. There have also been reports of some nice smallmouth bass being caught out of Martin Lake as well. The surface temperature of Horseshoe Lake is about 41 degrees. Horseshoe Lake is currently free of ice. Visitors have reported less success in Horseshoe, but some smaller trout are being caught. Variations of PowerBait including rainbow and cheese styles have been used to catch fish recently. 
Lathrop

St. Vrain

There are 11 fishable ponds at St. Vrain that are stocked on a regular basis. Bald Eagle Pond is artificial flies and lures only. Bald Eagle Pond and Blue Heron Reservoir are trophy bass fisheries: all bass caught on these 2 ponds must be immediately returned to the water! Only 1 catfish in your standard bag and possession limit can exceed 20 inches on Blue Heron Reservoir. Blue Heron has been producing some good sized Black Crappie, Largemouth Bass, and Saugeye on jigs and lures. Trout fishing is very productive in spring and fall depending on stocking. Stocked trout are only 8-10 inches in length and we do not recommend keeping them until they have matured and are of a healthy size: around 12-24 inches. Overfishing these waters results in smaller, less productive populations.
St. Vrain

Staunton

Our ADA accessible fishing pier is complete and ready to be fished from. Please contact the park about how we can provide an accessible fishing experience. Access to the ponds is from the main parking areas only. There is no public access below the dams on Elk Creek Road. Do not drop people or equipment off at this location. Violators will be ticketed.

Harvey Gap Reservoir

As of 3/20/2018, the lake was almost ice free. The water level in Harvey Gap was very low for much of the fall of 2017 as a result of a reservoir drawdown conducted by Silt Water Conservancy District to inspect the reservoir’s outlet. During this period of low water level, CPW put a public fish salvage regulation on the lake in which bag and possession limits were removed for all fish species. This public fish salvage is no longer active as it was removed once the reservoir started to refill. Conversations with anglers and a survey conducted by CPW in the fall immediately prior to the lake beginning to refill showed that the same species were present in the reservoir following the drawdown compared to prior to the drawdown (i.e. tiger muskie, rainbow trout, black crappie, bluegill, largemouth bass, yellow perch, channel catfish, northern pike, and smallmouth bass). In addition to stocking tiger muskie, rainbow trout, and channel catfish, CPW will be stocking increased numbers of bluegill and black crappie in 2018 to help the fishery recover from the drawdown more rapidly. Special fishing regulations at Harvey Gap Reservoir include a minimum size of 15 inches for largemouth bass and a bag and possession limit of 2 for channel catfish. Standard bag and possession limits apply for all other species. Bag and possession limits for smallmouth bass and northern Pike are unlimited. PLEASE MAKE SURE YOU CAN DISTINGUISH TIGER MUSKIE FROM NORTHERN PIKE. ALL TIGER MUSKIE LESS THAN 36 INCHES MUST BE RELEASED ALIVE. For more information regarding tiger muskie, please contact CPW Area Aquatic Biologist Ben Felt at benjamin.felt@state.co.us. Anglers may contact Harvey Gap/Rifle Gap State Park, 5775 Hwy. 325, Rifle, CO, 81650; Phone: 970-625-1607 for updates on fishing conditions.

Big Meadows Reservoir

This 114 acre reservoir is a State Wildlife Area southwest of South Fork. From Highway 160, access along Forest Road 410, currently the lake is only accessible by snowmobile, skis or snowshoes (2 miles). Because of its access restrictions and remote location, Big Meadows offers a good opportunity for anglers to enjoy a day of fishing away from the crowds while enjoying breathtaking views of nearby peaks in the Weminuche Wilderness. As of 3/8/2018 ice thickness is currently unknown and anglers are asked to use caution. Fishing has been good and anglers have been successful using worms at the upper end in the shallows. Fishing by the dam is also productive this time of year. For updated fishing reports and ice conditions, contact the Monte Vista office (719-587-6900).

Water temperature remains too cold for the crappie to have begun spawning. Some reports of large catfish being caught. Let us know what you are catching!
Crawford State Park

Mancos

As of 3/23/2018, the lake is mostly open water. Mancos is a great place for consistent action from rainbow 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+” 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. A park pass is required on vehicles in the park. Daily park passes are available at the self-serve pay station at the park entrance.
