Middle Fork at Santa Maria

Middle Fork at Santa Maria — Fishing Report for April 26, 2026

Quick Stats

Flow: 19 CFS | Trend: Falling | Fishability: Unfishable | Weather: Snow showers likely, high 43°F

The Bite

South Park is still locked in winter, and the Middle Fork at Santa Maria is no exception. Snow showers are in the forecast today and likely through Tuesday, with overnight lows dipping into the upper 20s. At 19 CFS and falling — well below even the low end of a typical April range — the meadow channels are barely moving, and any open water that exists is going to be brutally cold. Water temps aren't available from the downstream gauge, but given the conditions, expect readings in the low-to-mid 30s°F. Fish at those temperatures are essentially dormant, tucked into the deepest undercut banks and pools with their metabolisms dialed back to near zero.

This is also a notably dry water year across the South Platte basin — snowpack is running at just 16% of normal, and overall water-year precipitation is sitting around 65% of normal. The silver lining: runoff this spring should be modest and relatively short-lived, which could push the fishable window earlier than usual. But that window isn't here yet. The system needs several weeks of consistent warming before the brown trout in these meadow glides start moving and feeding in earnest.

If you're itching to fish the South Platte drainage this weekend, the tailwaters — Eleven Mile Canyon or the Dream Stream stretch — are a better bet. They hold more stable temperatures and can produce even in shoulder-season conditions.

What to Fish

• Midge Cluster (black/gray) #20-22 — only option if you find a slick of open water on a warm midday window
• Mercury Midge (red) #22 — dead slow presentation near bottom in any deeper pool
• Elk Hair Caddis (olive) #14-16 — early-season caddis scouts are possible late afternoon, but don't count on surface activity
• Caddis Pupa (green) #14-16 — file these away for May; the Mother's Day hatch is weeks out

Tactics & Rigging

If you do find a stretch of open water and decide to make a cast, go light and slow. A single small midge on 6X fluorocarbon, fished with almost no movement through the deepest part of any available pool, is your only realistic play. There's no hatch to match, no seam to work — just cold, slow water and lethargic fish. A tiny strike indicator set shallow can help detect the subtle takes that cold-water trout occasionally produce, but don't expect much.

Honestly, the better use of a trip to this area right now is scouting — note where the undercut banks are, where the deeper glides hold, and where the confluence structure looks promising. That knowledge will pay dividends when the system comes alive in June.

Access & Logistics

Respect private land boundaries carefully in the Santa Maria meadow area — several sections cross ranch property, and posted signs should be taken seriously. Road conditions into South Park may be affected by ongoing snow; check CDOT conditions before heading out. The open meadow landscape offers no wind protection, and today's snow showers will make for a raw experience on the water.

Verify current regulations with CPW before fishing — the confluence area with the main stem South Platte may carry special restrictions.

Looking Ahead

The 3-day forecast offers no relief — snow showers are likely through Tuesday with overnight lows near 25°F. Check back in late May as the Mother's Day caddis hatch builds toward its peak, and plan your first serious trip here for June when South Park finally thaws and the brown trout in these meadow pools start looking up.
