No access method is recommended today. Skip this reach for now. Review the live flow and current notices before choosing another reach or day.
Check first: Water temperature is unconfirmed. Use a stream thermometer before fishing.
Rating updatedRiver local time:
Colorado DWR shows 1 cfs. The flow has been stable over about 6 hours. PLACHACO at 5 cfs or less is an extreme-low stop for the immediate below-reservoir fishing call. Do not float or force a wade; this conservative planning rule is not a CPW closure. Colorado DWR records for this date (1986-2025, 40 readings) show a median near 12 cfs and the lower quartile near 1 cfs; today's flow is below normal for the date. Colorado DWR PLACHACO measures discharge on the South Platte River immediately below Chatfield Reservoir. It does not report current water temperature, clarity, safe footing, open access, or downstream Littleton conditions.

Seasonal starting points, not a live hatch report. Match what you see on the water.
Use the date range as a starting box, then let the feeding and water you can actually see choose the fly.
Each pictured fly opens its matching Fly Box guide. These are seasonal planning choices, not a live hatch report.
Make this a short below-reservoir plan. A reading above the extreme-low cutoff is not an automatic green light. Access, temperature, clarity, footing, weather, and the release trend still decide whether to bank fish or wade.
Treat the automated call as poor. Do not float, do not force a wade, and inspect whether a lawful bank session is even practical.
This removes one stop condition. It does not prove good fishing, safe wading, suitable temperature, clear water, or open access.
Stay on a protected bank and leave if depth, current, footing, or a safe exit becomes uncertain.
Check the exact river with a thermometer and inspect it from shore. Stop for unsafe weather or trout-stressing water.
No access method is recommended in today's conditions. Review the live river and weather checks before making another plan.
Not recommended today. Recheck the river, weather, and access before planning another trip.

This report does not recommend floating this reach.
This report covers the South Platte River below Chatfield Reservoir through the South Platte Park corridor. Check the PLACHACO flow, exact access, weather, and current rules before choosing a bank or wade plan. It is not a Chatfield Reservoir fishing report.
PLACHACO measures the river immediately below Chatfield Reservoir. Start on the bank. Wading is conditional, and this report does not recommend floating.

Fall · September through November: Cooler weather can improve the window; BWOs, midges, terrestrials, and a small streamer cover the main choices.
The current NWS air forecast is about 57F, and the next 24-hour high reaches about 80F. Partly Cloudy.
No active NWS alert was returned for this forecast point.
Skip at an extreme-low call, for rising or pushy water, unsafe heat or storms, poor footing, unclear access, or an official restriction affecting the plan.
Use a fresh PLACHACO reading and trend. Above 5 cfs removes the extreme-low stop but does not prove good fishing, safe wading, suitable temperature, clear water, or open access.
Skip at an extreme-low call, for rising or pushy water, unsafe heat or storms, poor footing, unclear access, or an official restriction affecting the plan.
Check PLACHACO, the Chatfield park page, current CPW rules, and weather. Then choose one confirmed bank and inspect the water before rigging.
Check Waterton, Deckers, or the North Fork independently. Another South Platte page is not automatically safer, open, or fishable.
When: Cool, fishable river conditions
Use the small-nymph, dry-fly, and compact-streamer plan only when the river and access checks support it.

Verify the exact Littleton reach separately. A downstream species record is not a promise below the dam.
This score is for the river immediately below the reservoir. South Platte Park is a separate downstream access and condition check.
Open the current CPW Fishing Brochure, Fishing Atlas or closure list, and posted park signs for the exact river reach and trip date. This river report is not the Chatfield Reservoir report, and it does not freeze numeric limits that may change.

No. It covers the South Platte River immediately below Chatfield Reservoir. Use a reservoir-specific source for lake fishing, boating, stocking, and lake conditions.
Colorado DWR PLACHACO supplies the live discharge for the river below Chatfield Reservoir. RiverReports supplies the companion chart. No substitute station is used.
No. It reports discharge. Measure water temperature at the river and use current park pages, CPW rules, closures, and posted signs for access.
This report does not recommend a float route. South Platte Park says floating is not recommended at 50 cfs or less in its separate downstream recreation reach. That guidance is not a fishing closure and does not verify a launch, takeout, shuttle, craft, PFD, or obstruction plan.
Use CPW's current Fishing Brochure, Fishing Atlas or closure list, plus posted signs, for the exact river reach and trip date. Do not copy reservoir or another South Platte section's rules onto this reach.
