SPRING HOURS 9am to 6pm Daily

 

Report Date: 5/16/2026

Current Conditions: 

  The flows from Cheesman have been coming up over the last few days. Current flows are at 314 cfs. and excellent for this time of year. These flows will really change the canyon and open up a lot more fishing opportunities. Higher flows will spread fish out more, and the fish will be more comfortable to eat. The river is still fishing technical as always, but this is a good time to augment some larger food sources into the mix. Scuds, craneflies, worms, and stoneflies will all be good choices with these flows. Focus on seams and areas of the river with some slower side pockets. The visibility is a little off but should clear up fast. 5x is still a good idea and the fish still want perfect drifts. These are some of our favorite flows for the canyon. We have no idea how long this will last, so get out and enjoy it!!  Nymphing has and will be the most productive method right now. The dry fly fishing should turn back on once these flows stabilize for a couple of days.

Cheesman reservoir is currently 82% full and starting to fill with Antero's water.
Hatches:
 Midges and BWO's are the staples. We are seeing good action in both subsurface and adult activity.  Subsurface is always the most consistent, but we have also had some great dry fly fishing for adult midges and BWO's! Caddis are starting to become more important as well. Again, adding scuds, stoneflies, cranefly larva, or worms to the regular hatching insects is a good idea right now.
Tactics:
  These are great flows for straight line or drop shot style nymphing. Depth and weight of your rig will be key right now. Make sure your flies are getting down!!
Tips:
Water temps are still pretty cold in the canyon. But the weather has been hot. Its best to hike in without waders and then put them on once you are in your spot.

Weather:

Short Term-  We will see some very nice springtime temps up here in the next few days. High temps will be in the 70's, and we will see some decent cloud cover at times. Precipitation chances will increase on Saturday and more so on Sunday. It looks like we are entering another good stretch of cooler and wetter weather starting on Sunday. Temps will cool quite a bit on Monday and Tuesday and we should see some rain or maybe even wet snow. Morning lows will also get chilly at the beginning of next week.  We will even see some good snow fall in the high country. This unstable pattern looks to last through next week, but temps will warm back up again. We are excited at the prospect of some sustained moisture returning to the area!

Long Term-  Precipitation chances look to continue through the Memorial day weekend as well. Temps will be nice in the 70's, but we should see afternoon thunderstorms pretty consistently each day. These storms will start to develop around noon and some of them could be severe. In all, this is about the best case scenario for us here. We need the rain and by all accounts, it looks like we will get some. Longer range forecasts also show increased precipitation chances through May and into June. As always, we will have to wait and see how that all shakes out.

Cheesman Canyon is one of the most technical and rewarding tailwater fisheries in Colorado. A half-hour hike from Gill trailhead through some hilly terrain gets you to the base of the canyon where the trail splits into a high road and low road. This stretch of the river is catch and release only and is known for holding large rainbows. Almost the entire length of the river that runs through this gorgeous boulder-filled canyon is loaded with deep pocket water and fast runs that provide different challenges depending on where the fish are located. Most of the time the fish are hanging close to undercut boulders and other structure.

Before going to Cheesman, load your box with these patterns: Cheesman Emergers #22-24, Amy's Ants #10-14, hoppers #8-10, Murphy's Bubbleback Midge #20-24, Blindside Midges #20-22, Dorsey's Top Secret and Medallion Midges #22-24, Stonefly nymphs #14-18, Caddis larva #16-20, Tan and orange scuds #14-18, Sparkle Wing RS-2's #18-22, BWO Barr's Emergers #20-22, Copper Johns, Black Beauty #22-24, and Stalcups baetis #20-22.

My favorite stretch of the South Platte. What can I say: technical, challenging, humbling, and rewarding. It is often said that if you can catch fish in Cheesman Canyon, you can catch fish anywhere.
