Fall River Fly Fishing Report - January 1/4/2026

Fly Fishing Report

FALL RIVER FLY FISHING REPORT

Northern California — Fall River (Upper Sections)

Report Date: January 4, 2026  |  Next Update: January 11, 2026

Current River Conditions

Winter routine on the Fall River: spring‑fed flows are low and steady, visibility is generally very clear but short in deep winter light—fish are holding in seams, eddies and pocket water. Expect prime nymph and streamer windows; a few afternoon emergers and midges can trigger selective rises.
Flows & Clarity
Flow Character: Spring‑fed, low and steady (fishable year‑round above the falls).
Water Clarity: Very clear; pick seams, foam lines, and soft tails where trout feel secure.
Water Temperature
Typical early‑January: in the low 40s °F (water is cold and fish are less aggressive — slow, accurate presentations win).
Weather & Wind
Forecast (short term): chilly mornings, afternoons milder with sunshine breaks; light to moderate winds at times. Dress warm and layer.
Access & Regulations
Upper Fall River (above the falls) remains open and is best this time of year. Note: sections below Fall River Falls have seasonal restrictions/closures into spring — check state pages before heading out. Always carry 2026 license, follow posted rules, and use barbless hooks where required.

Hatch Chart & Insect Activity (early Jan)

Insect Size Activity Prime Time
Midges (all sizes) #18–24 Heavy — main winter food All day (pick calm pockets)
Blue‑winged olives (BWO) #18–22 Light‑moderate (afternoon) Midday to afternoon
PMDs #16–20 Occasional Afternoon
Caddis #16–20 (small) Low — evening pockets Late day to dusk
Stoneflies / Salmonflies #4–10 Absent to very low (winter) Not expected
Terrestrials (ants/beetles) #10–16 Low—spotty (warm days) Warm afternoons

Recommended Flies & Patterns (practical picks)

Below are the best choices right now on the Fall River. I grouped them by method so you can build a focused four‑box that covers the day. Each pattern includes a direct link so you can check size options and pick up extras before you go.

Dry Flies & Emergers (for selective moments)

Nymphs (the workhorse winter arsenal)

Split/Beadhead Nymphs & Emerger Nymphs

Streamers & Baitfish Imitations

Terrestrials & Hopper/Ant Options (warm afternoons)

Midges & Tiny Winter Patterns

Stonefly / Big Nymph Options (if you locate big stonefly pockets)

Tactics & Quick Tips

Start with nymphs. Winter Fall River fish want subsurface offerings—rig a tungsten point fly or a jigged Frenchie at the business end and a slimmer attractor upstream. Euro or indicator nymphing are both highly effective.

Midge strategy: when chips of midge life are obvious, downsize to a thin zebra midge or micro peridgon and fish slow, tight drifts near the bank or behind rocks.

Streamer windows: use dead‑slow, weighted streamers along deep tails, undercuts, and near structure. Long pauses and short strips often trigger the hit in cold water.

Dry fly opportunities: afternoons with sun and calm water bring selective risers (BWO/PMD). Fish small, realistic emerger/dun patterns and keep tippet fine (6x–7x where legal).

Presentation & rigging: keep leaders short and light for dries; use tungsten beads and dropper lengths of 8–12" for deep runs. Match depth with bead weight and keep a couple of split‑shot rigs for slower seams.

Etiquette & safety: winter water is cold — wade cautiously, fish with a buddy when possible, and respect private property and other anglers. Park considerately and pack out everything you bring in.

Local Notes & Final Advice

Reports heading into early January show steady, clear conditions and reliable nymphing on the Fall River. Crowds usually thin after the holidays — a weekday morning gives the best solitude. If you plan to fish below the falls or targeted regulated reaches, double‑check the state fisheries page before you leave: seasonal closures and barbless/hook rules can change with management orders.
