Where to Go Middle Fork of the South Platte

Open 9 am to 6 pm Daily

Report Date: 10/21/2026

 Voluntary closure 12 pm - 12 am daily - CPW

Conditions:

Flows on the Middle Fork of the South Platte remain low and clear across the South Park valley. Fish are holding in deep pools, under-cut banks, and slow meandering bends where they can escape the bright sun. Anglers should keep a close eye out for spawning brown trout on shallow gravel tailouts and steer clear of active redds.

Weather:

Short-Term

Clear, bright high-plains skies will dominate over the next 3 days, pushing afternoon highs into the mid-to-upper 50s. Cold dawn starts in the 20s give way to sun-driven warming, while typical open-prairie afternoon gusts will build to 10–15 mph, adding a helpful surface chop across glassy meadow glides.

Long-Term

The 10-day regional outlook points to a stable early-autumn pattern across South Park. Highs will gradually level off in the low 50s with overnight freezes routinely dipping into the low 20s. Steady tailwater releases out of Spinney Dam will buffer subsurface water temperatures, keeping feeding windows predictable during mid-day thermal peaks.

Hatches:

Midges provide the primary subsurface activity through the morning hours, while sporadic Blue-Winged Olives occasionally hatch on overcast stretches of the day. Surface terrestrial activity has largely faded, though an occasional stray insect may still drift down on breezy afternoons.

Tactics:

Ultra-low 27 cfs flows through wide, open prairie margins make bank stealth critical. Stay low, lengthen setups to 10–12 feet tapered to 6X fluorocarbon, and swap plastic indicators for sensitive wool or micro-putty. Minimal split shot is required to reach fish in these shallow, slow-moving channels without spooking the pool.
