Use caution

Verify conditions before committing.

Current USGS flow is 184 cfs and has been stable for about 6 hours. Today's flow is below the normal seasonal range, which begins near 236 cfs. This is below normal, so edge depth, temperature, and pressure matter.

Before choosing how to fishCheck the water first

There is not enough reliable current information to recommend wading, bank fishing, or floating.

Wade, bank, and floatLimited data

Use the live sources and what you see at the river before choosing an approach.

Check before you drive

Current flow and weather.

Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

Before you rely on this report

How current is this report?

Conditions can change quickly. Check these dates before you decide to fish, and open the official source when safety or rules matter.

How to fish it

This page is the Deckers and Cheesman plan.

The South Platte name covers many different fisheries. This report focuses on the Deckers, Cheesman, and South Platte corridor plan, while Eleven Mile Canyon and the forks have their own pages.

Use RiverReports and USGS 06701900 for the Deckers-area flow reference.
Denver Water identifies Cheesman Canyon as Gold Medal water with designated parking and public access constraints.
Expect technical fish, clear water, heavy pressure, and small-fly presentations.
Private land and posted signs matter, especially outside designated public corridor access.

Why the score looks this way

FlowUse caution

USGS shows 184 cfs with a stable over about 6 hours trend. Today's flow is below the normal seasonal range, which begins near 236 cfs. This is below normal, so edge depth, temperature, and pressure matter.

HeatUse caution

The NWS forecast is near 93F. Fish early and verify water temperature where trout stress is possible.

Public alertUse caution

An Air Quality Alert is active near this forecast point, so the score is capped at caution until smoke and access conditions are checked. NWS alert: Air Quality Alert issued August 2 at 4:10PM MDT by NWS Denver CO.

SeasonHelps score

Summer: PMDs, caddis, yellow sallies, tricos, and terrestrials matter, especially in low light.

Fishing usefulnessHelps score

Skip the Deckers and Cheesman plan when parking and crowding leave no clean water, when wildfire or corridor restrictions change access, when section rules are unclear, or when higher flows remove safe wading in the water you intended to fish.

Read the water

What changes the plan.

The South Platte around Deckers fishes best when flows are stable, clarity is good, and you are willing to fish precisely. Small nymphs and careful dry-fly presentations often beat broad searching.

Low clear flow

Use 5X to 7X, small flies, long leaders, and very careful wading.

Stable medium release

Nymph riffles, slots, and tailouts; watch for short dry-fly windows.

High release or storm bump

Fish soft banks and avoid unsafe crossings. Stain can make streamers and larger nymphs useful.

Hot or crowded day

Fish early, give other anglers room, and move rather than camping on pressured fish.

Your trip plan

Know when to go—and when to skip it.

Best flows

Use the Deckers trend as the anchor. Stable releases are the cleanest signal for classic technical nymphing and short dry-fly windows; a storm bump or larger push should move you to softer banks, streamer water, or another branch with more room.

When to skip

Local plan

Decide whether the day is Cheesman canyon water, the easier Deckers corridor, or a backup branch before you rig. That choice determines hiking load, fly size, parking strategy, and how much crowd tolerance you need.

Backup water

If Deckers and Cheesman are too crowded or pushy, pivot to Eleven Mile Canyon for another technical tailwater day or to the North Fork or Middle Fork only after checking those separate pages for their own access and rule differences.

Hatches & flies

Bring a flexible box.

TimingWhat to watchUseful flies

WinterMidges and tiny olivesZebra midge, black beauty, top secret midge, RS2

Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it

Fly pattern · report suggests “black beauty”Black Beauty MidgeA very slim black thread body, fine silver rib, and small dark thorax define the core Black Beauty. Glass-bead Mercury Black Beauty and flash-wing variants must stay labeled separately.See photos & how to fish it + 2 more reviewed guides in the Fly Box

SpringBWOs, midges, caddisBWO emerger, juju baetis, caddis pupa, mercury midge

Fly family · report suggests “BWO emerger”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide

Fly pattern · report suggests “juju baetis”Juju BaetisA narrow segmented body, dark wing case, compact thorax, and sparse tail define the Juju Baetis. Bead, color, and flash choices are meaningful variants.See photos & how to fish it + 2 more reviewed guides in the Fly Box

SummerPMDs, caddis, tricos, terrestrialsPMD emerger, elk hair caddis, trico spinner, ant, beetle

Fly pattern · report suggests “elk hair caddis”Elk Hair CaddisLook for a tented elk- or deer-hair wing, clipped hair head, dubbed body, rib, and hackle palmered along the body. The body color should be labeled because tiers often match different natural caddis colors.See photos & how to fish it

Fly family · report suggests “PMD emerger”Pale Morning Dun PatternsPMD names an insect group, not one fly. Pale nymphs, trailing-shuck emergers, upright or low-riding duns, cripples, and spent-wing spinners stay visibly separate.See family guide + 3 more reviewed guides in the Fly Box

FallBWOs, midges, October caddisBWO dry, zebra midge, October caddis pupa, small streamer

Fly pattern · report suggests “zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it

Fish one good lane well instead of covering water loudly.

Adjust depth and weight before assuming the fly pattern is wrong.

Use stealth in Cheesman and Deckers clear water; shadows and repeated false casts matter.

Respect other anglers and avoid walking through active water.

Keep a backup plan for North Fork, Tarryall, or Eleven Mile if parking or crowding is bad.

Common questions

Before you leave.

Which South Platte reach is this page about?+

It focuses on the Deckers and Cheesman corridor. Eleven Mile Canyon, the North Fork, and the Middle Fork have separate pages.

What flow should I check for Deckers?+

Use RiverReports and USGS 06701900 for the Deckers-area flow reference.

Why is the South Platte so technical?+

Clear water, heavy pressure, small insects, and selective trout make drift quality and approach very important.

What flies should I bring?+

Bring midges, RS2s, BWOs, PMDs, tricos, caddis, small terrestrials, and a few small streamers.
