Should I go fishing?

Check the water temperature first.

Water temperature is unconfirmed. Use a stream thermometer; stop trout fishing at 70°F or warmer, or sooner if fish show stress.

Why this recommendation?

USGS shows 25 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (2018-2025, 8 readings) show a median near 46 cfs and the lower quartile near 35 cfs; today's flow is below normal for the date. This is below normal, so edge depth, temperature, and pressure matter.

If you go

Check first
RiverReports gives the flow chart for this page, with USGS 09352800 as official backing near the lower river context.
Try
Confirm access first. If the reach is private or unclear, do not fish it just because the water looks good.
Leave when
Skip when access is unclear, the river is in heavy runoff, storms are building, or lower water is too warm for trout.

Methods, fish species and trip notes

How to fish Los Pinos River today.

The best public-facing plan is usually a summer or early fall trip after runoff settles, with clear access boundaries and a backup if the river is too high, warm, or restricted.

Low clear water

Use smaller dries and nymphs, longer leaders, and careful approach angles.

Moderate stable flow

Best condition for dry-dropper rigs, caddis activity, and riffle-edge nymphing.

Runoff

Fish only protected edges if safe and legal, or wait for a clearer drop.

Warm lower water

Carry a thermometer and shift away from trout when temperatures are stressful.

Wading, bank fishing or floating?
Access choicesNo single best option

Wading and Floating have the same top score. Use current access, footing, weather, and local rules to choose.

Wading74/100

Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

Bank fishingNot recommended

This report does not recommend bank fishing on this reach.

Floating74/100

A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.

Is Los Pinos River worth the trip today? Check flow, weather, hatches, access, and rules for Colorado before you go.

The Los Pinos can be very useful for trout planning, but access is the first filter. Use flow and weather checks, then confirm whether your plan is on public land, a legal easement, or private or tribal water.

Fishing words used on this page
U.S. Geological Survey (USGS) gauge
A USGS gauge is an official river station that measures flow or water height.
Cubic feet per second (cfs)
Cubic feet per second, or cfs, shows how much water passes the gauge each second.
Nymph
A nymph is a young water insect. Anglers also use the word for a fly that copies it.
Riffle
A riffle is shallow, fast water broken by rocks.
Seam
A seam is the line where fast and slow water meet.
Blue-winged olive (BWO)
Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
Caddis
Caddis are small water insects. The adults look a little like tiny moths.
Dry-dropper
A dry-dropper rig has a floating fly with an underwater fly tied below it.
Emerger
An emerger copies an insect as it rises from below the water toward the surface.
Midge
Midges are tiny flies and a common trout food, especially in cold water.

FlowUse caution

This is below normal, so edge depth, temperature, and pressure matter.

SeasonHelps

Early fall: Often the best mix of stable water, cooler nights, and lower pressure.

WeatherHelps

The current NWS air forecast is about 62F, and the next 24-hour high reaches about 78F. Partly Cloudy.

Public alertsHelps

No active NWS alert was returned for this forecast point.

Fishing usefulnessHelps

Skip when access is unclear, the river is in heavy runoff, storms are building, or lower water is too warm for trout.

Trip notes

Check these before you choose a reach.

Best flows

Stable post-runoff flows with clear banks, safe wading, and trout-safe water temperatures.

When to leave

Skip when access is unclear, the river is in heavy runoff, storms are building, or lower water is too warm for trout.

Local plan

Start with access boundaries, check flow and weather, fish one clearly legal reach, and keep the Animas as a backup.

Backup water

Animas River is the easiest nearby backup when access or flow makes the Los Pinos plan uncertain.

Los Pinos River access and rules.

Use these places as starting points. Open the access link below and check posted signs before you park or enter.

Before you go

Check current Colorado fishing rules and local access rules before fishing. Parts of the broader drainage involve private land or Southern Ute Reservation context, so public access should be verified before you step in.

Where to access the river

San Juan National Forest river and stream fishing areas

Use Forest Service access information as the public-land planning starting point.

Pine River Trail context

A useful upper-drainage public-land concept, with distance and road planning required.

Lower valley checks

Useful for flow and condition awareness, but private and tribal boundaries require extra care.

  • The public-access question is the main planning issue on this river.
  • Some lower-river opportunities are private, guided, or connected to tribal jurisdiction. Do not rely on secondhand access assumptions.
  • Use official public-land and rule sources before choosing a reach.

If this water does not fit the day, check another report before you start the drive.

Trip guidance checked

What was checked: This report uses official regulation, flow, weather, access, and public-land sources first, then adds practical planning guidance for fly anglers.

Live measurements and forecasts keep their provider timestamps. Rules, access, and trip guidance use the source-review date shown here. BlueStreamFly planning advice is editorial interpretation, not an agency notice.

Quick questions

Is the Los Pinos River all public?

No. Access is the first thing to verify because parts of the drainage involve private land or tribal context.

What flow source should I check?

Use RiverReports for the quick chart and USGS 09352800 for official backing.

What is the best fishing style?

Once flows settle, a dry-dropper or light nymph rig through banks, riffles, and soft seams is the practical starting point.
