Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

Los Pinos River
A practical Los Pinos report for San Juan mountain access, RiverReports flow support, official USGS context, private-water cautions, and trout tactics.
Check flow & weatherLos Pinos River is a cautious call right now.
Current USGS flow is 40 cfs and has been stable for about 6 hours. Today's flow is above the usual high-water marker for this date; the seasonal median is 75 cfs. Treat this as high-water fishing: wading, clarity, crossings, and boat control need a conservative check.
Compare wading, bank fishing, and floating before choosing how you will fish.
This report does not describe this as a primary mode. Verify legal access, depth, launches, and retreat options before planning around it.
A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

Public land
San Juan National Forest river and stream fishing areas
Use Forest Service access information as the public-land planning starting point.
Restrictions and seasonal notes
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.
Trailhead
Pine River Trail context
A useful upper-drainage public-land concept, with distance and road planning required.

How to fish it
Start with access boundaries, then fish the water you can legally reach.
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.
- RiverReports gives the flow chart for this page, with USGS 09352800 as official backing near the lower river context.
- San Juan National Forest lists river and stream fishing opportunities and Pine River Trail access in the district.
- Private land and Southern Ute Reservation context matter on parts of the drainage, so do not assume a visible river is open to public fishing.
- Fish early in summer, watch storms, and carry a thermometer where lower water warms.
USGS shows 40 cfs with a stable over about 6 hours trend. Today's flow is above the usual high-water marker for this date; the seasonal median is 75 cfs. Treat this as high-water fishing: wading, clarity, crossings, and boat control need a conservative check.
Float: A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
Summer: Primary public-trip season once high water settles and access roads are reliable.
The NWS forecast is about 80F with Mostly Clear.
No active NWS alert was returned for this forecast point.
Read the water
What changes the plan.
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.
Your trip plan
Know when to go—and when to skip it.
Stable post-runoff flows with clear banks, safe wading, and trout-safe water temperatures.
Skip when access is unclear, the river is in heavy runoff, storms are building, or lower water is too warm for trout.
Start with access boundaries, check flow and weather, fish one clearly legal reach, and keep the Animas as a backup.
Animas River is the easiest nearby backup when access or flow makes the Los Pinos plan uncertain.
Hatches & flies
Bring a flexible box.
Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly family · report suggests “BWO emerger”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide ↗+ 2 more reviewed guides in the Fly Box
Fly pattern · report suggests “Elk hair caddis”Elk Hair CaddisLook for a tented elk- or deer-hair wing, clipped hair head, dubbed body, rib, and hackle palmered along the body. The body color should be labeled because tiers often match different natural caddis colors.See photos & how to fish it ↗
Fly family · report suggests “PMD”Pale Morning Dun PatternsPMD names an insect group, not one fly. Pale nymphs, trailing-shuck emergers, upright or low-riding duns, cripples, and spent-wing spinners stay visibly separate.See family guide ↗+ 3 more reviewed guides in the Fly Box
Fly family · report suggests “beetle”Beetle PatternsBeetle flies range from simple foam shells to hair-bodied and sunken forms. A rounded back and compact profile distinguish the family from ants and hoppers.See family guide ↗
Fly family · report suggests “caddis pupa”Caddis Pupa PatternsCaddis pupa is a life-stage family. Curved bodies, wing pads, legs, beads, and soft-hackle collars differ among exact patterns and must be labeled.See family guide ↗+ 1 more reviewed guide in the Fly Box
Fly pattern · report suggests “RS2”RS2Start with the beadless architecture: two dark-dun Microfibett tails separated behind a slim, tightly twisted and visibly segmented dubbed abdomen; a fuller thorax; and saddle-hackle web clipped into a short angled wing bud. Rim Chung's original-style form uses natural beaver dubbing and hackle web. CDC- or Antron-wing ties, beads, curved hooks, flash, and tailless Avatar-style flies must remain labeled variations.See photos & how to fish it ↗

If the reach is private or unclear, do not fish it just because the water looks good.
On public water, fish banks and riffle transitions before walking through them.
Use dry-dropper rigs once summer flows settle, and switch to nymphs if fish stay low.
Keep a backup in the broader San Juan drainage if storms, access, or flow shut down the first plan.

Common questions
Before you leave.
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.
