North Fork South Platte Fishing Report

Bailey · Pine · Colorado

Plan your visit to the North Fork South Platte with fishing conditions, Bailey river flows, suggested flies, and practical advice from Blue Quill Angler.

ON THE WATER

Current fishing report

Report updated

The North Fork near Bailey can change quickly with Roberts Tunnel operations, so a flow check is essential before fishing. Late October generally brings colder mornings, clearer water and a stronger emphasis on midges and Baetis. Where the river has adequate depth and current, a compact dry-dropper rig can still search pockets efficiently; a caddis or buoyant attractor can support a small Pheasant Tail or Juju Baetis. In deeper seams, a two-nymph setup may be more effective than searching with a dry. Trout in clear, shallow water can be wary, so work upstream carefully and fish near-bank holding spots first. Respect private-water boundaries and avoid brown trout redds and actively spawning fish.

Fishing tips

Check tunnel-influenced flows before traveling and confirm public access. In well-watered pockets, fish Elk Hair Caddis or Chubby Chernobyl over a Pheasant Tail. Use Juju Baetis and Zebra Midge in deeper seams; switch to a Blue Wing Olive dry only when fish rise.

Tips & Other Information

The North Fork of the South Platte is fishing excellent right now.  The truth be told, the North Fork of the South Platte is a great option! The flow is currently 159 cfs in Bailey and ice cold which is a huge benefit to fishing on the North Fork. This is good news as the North Fork is providing downstream demand to the metropolitan area and outlying farmland.  Egg patterns, San Juan Worms and flashy nymphs have been effective as of late. The dry fly fishing has been good too with small black gnats, midge clusters, and larger patterns like Chubby Chernobyles and Amy’s Ants. The fish are looking up! Dry and droppers are a good option too in the skinny water.

Fishing North Fork South Platte

The fishery

The North Fork South Platte offers varied fishing around Bailey and downstream toward Pine, with riffles, boulder pockets, deeper slots, and sheltered feeding lanes. Conditions vary with location and Roberts Tunnel deliveries, so check flows before selecting a reach. A short, controlled presentation can be effective in pocket water, while deeper runs require careful depth adjustments. Public access is limited in places; a promising stretch of river is not necessarily open to fishing.

Access & parking

Confirm legal public access or obtain permission before approaching the North Fork. Much of the river corridor includes private property and managed fishing water. Pine Valley Ranch Park provides a public-access option downstream from Bailey; consult the park map and follow posted boundaries and rules. Use designated parking and established trails, and avoid assuming that road frontage or an informal path establishes public access.

Seasons & techniques

Midges and small mayflies provide useful cool-weather options, while warmer periods can bring caddis and terrestrial activity. A dry-dropper can cover healthy pocket water efficiently; a short nymph presentation suits deeper slots and seams. Roberts Tunnel deliveries can change the flow independently of local weather, so check the current gauge and observe conditions on arrival. Avoid thin water, concentrated fish, and spawning areas.

Regulations & river care

Check current Colorado Parks and Wildlife fishing regulations and the rules for the specific public property or private fishery you plan to visit. Respect access boundaries, posted closures, and other anglers. We encourage catch and release, minimal handling, and keeping trout in the water while unhooking them. Avoid spawning fish and redds. Changes in flow, slippery rocks, and narrow channels require cautious wading and careful choices about crossings.
