Season windows

No dated harvest closure published

Empty windows mean the cited source published no defensible dated harvest closure — a completed check, not a gap. Harvest is not assumed open. Bag, size and gear still apply.

Provenance

2026-09-08 review: IDFG 2025-2027 Fishing Seasons and Rules brochure. Every region publishes "All Waters Open All Year, except as modified in the Special Rule Waters". The Memorial Day to Nov 30 pattern this rule previously applied statewide appears only inside individual Special Rule Waters entries, and the prior note said so itself: it was "applied as statewide default". A dated closure this catalog inferred is worse than no window, because it reads to a reader as something the agency published. Empty seasonWindows = no dated closure at general-rules level, not an unchecked gap.

Same-day unresolved

  • Look up this exact river in the IDFG Special Rule Waters list — many flowing waters do carry a dated season or a winter catch-and-release rule there.
  • Same-day IDFG check required at https://idfg.idaho.gov/rules/fish

What's in this reading

Five layers on this water

Open a layer to see the documented signals behind it and the unknowns it cannot close. Every layer reports what an agency published — none of it is an observation of the water today.

What the record says

What this read cannot tell you

  • Same-day gate hours, fees and closures are set locally and are not mirrored here.
  • Facility condition (surface, dock presence, ADA status) is not tracked at record level.
  • Landowner boundaries adjacent to public corridors are outside this dataset.

Support is a hand-set weighting of how much documented material this layer rests on. It is not a probability and nothing here was measured.

Species context

What the agency documents here

Presence context only. This is never an expectation of catch, and carries no statement about timing, forage or activity. A note in brackets is the agency’s own condition on that fish and it outranks everything else on this page. Behaviour and presentation are the next instrument’s question — carry a species forward from the section below.

All of them at once

Decision

4 species, one temperature

Published bands for every species this record names. Put a temperature in to see where the water sits against them.

354555657585°FCutthroat troutRainbow troutBrown troutMountain whitefish
Inside the band The water is in the range this species was measured preferring.
Within two degrees A band endpoint is a laboratory summary rounded to a degree or two. Calling 71° comfortable and 72° out would give it a precision the source never claimed.
Tolerated, not preferred Outside the preference and inside the wider range the same source publishes — the faint bar behind each row. A great deal of fishing happens here.
Outside both Outside every published range. Still catchable — the band says where a fish is comfortable, not where it can be caught.
Rules on file Statewide season and limits are recorded for 1 of these species. They are below, and they are not the rules for this water.

Nothing here ranks the species or scores the day. A fish outside its band is often exactly why people go, and turning a comfort range into a verdict would invent the one thing this catalogue exists not to invent. One band per species is a summer simplification — warmwater fish shift their preference ten degrees or more between winter and summer in the same laboratory. Species this record names with no reviewed band are absent from the drawing and listed under the plate below it.

Temperature

Where a reading would sit against the published bands

These are reviewed temperature bands for the species the agency documents here, each one carrying the source it came from. They describe the fish, not this water. Nothing on this page knows what South Fork Snake River (public access corridor) is doing today — put a thermometer in it and the drawing will show you where that number lands.

Detail

Temperature

Cutthroat trout

Measured preference. A band for the species, not a forecast for South Fork Snake River (public access corridor).

40455055606570DEGREES F
Preferred 51.1–58.3°F The core. Where the reviewed record says this fish would rather be.
Active 46.4–68°F Feeding happens across this range. Wider than the core, and the edges are where a day gets difficult rather than impossible.
Edges Warm or stressed from 67.3°F up. Outside the edges the fish is still there — it is just doing something other than feeding where you can reach it.
What you have No water temperature entered. This is the single measurement that moves the reading most, and a cheap thermometer beats a forecast every time.
What kind of number this is A measured preference. The fish chooses this range when it can, which is the kind of number worth planning around.
From the source Westslope cutthroat specifically: optimum growth 13.6 °C, fundamental thermal niche 10.6–14.6 °C. Fish became lethargic and stopped feeding as water approached 20 °C, which is why the warm edge sits where it does.
What this plate is telling you

Naming. This record documents Yellowstone cutthroat trout; the reviewed band was published under Cutthroat trout. Worth knowing before you lean on the numbers — the closer a name is to a regional one or a subspecies, the more the band is a reasonable neighbour rather than the same fish.

What the edges are. No cold edge published. Warm edge: 60-day upper lethal; feeding ceases approaching 68 °F. These are not one consistent quantity across species. A measured avoidance temperature is where fish were seen leaving; a water-quality maximum is a regulatory ceiling written to prevent a kill, and it sits well above the point a day gets difficult.

Source. Bear, E.A., T.E. McMahon & A.V. Zale 2007, Comparative Thermal Requirements of Westslope Cutthroat Trout and Rainbow Trout, Transactions of the American Fisheries Society 136:1113–1121. Read it.

Warmwater species swing their preference ten degrees or more between winter and summer in the same laboratory. One band per species is a summer simplification, and it is why the drawing shows a band rather than a line.

Altitude matters more here than people expect. The same water at 9,000 feet holds about a quarter less oxygen at saturation than it would at sea level. Leave it blank for sea level.

Oxygen

What this water could hold, against what the standard asks

Enter a water temperature above and the ceiling for this water appears on the curve.

03691215405060708090WATER TEMPERATURE °FDISSOLVED OXYGEN mg/L
Saturation curve The most oxygen fresh water can dissolve at each temperature, corrected for the elevation entered. Physics, not biology: it falls as the water warms.
Your reading No water temperature entered yet. The same thermometer that answers the temperature question answers this one.
Which column applies Chosen from the fish this record documents — . A record naming both trout and warmwater species takes the coldwater column, because a criterion is a floor and the stricter floor is the one protecting what is there.

Saturation is the most this water could hold if it were in equilibrium with the air. Real water sits below it — respiration, decomposition and a weed bed at four in the morning all take oxygen out — so the curve is an upper bound on a good day, never a measurement. Only a meter in the water tells you what is actually there.

What this plate is telling you

Why the curve falls. Gas solubility drops as temperature rises. Water at 80°F cannot hold what the same water held at 50°F, whatever lives in it. That is why a summer warm spell and a fish kill turn up in the same week, and why the cold layer at the bottom of a stratified lake — perfect temperature, no resupply from the surface since spring — can be the emptiest water in it.

Sources. Benson & Krause 1984, Limnology and Oceanography 29(3):620–632, in the form USGS publishes for DOTABLES for the curve; U.S. EPA 1986, Ambient Water Quality Criteria for Dissolved Oxygen, EPA 440/5-86-003, Table 8 for the lines.

What this is not. Not a reading, not a forecast, and not a statement about South Fork Snake River (public access corridor) on any particular day. Agencies publish measured dissolved oxygen at many gauges — that number outranks everything on this drawing.

Statewide rules

Idaho’s general season and limits

These are the statewide rules for 1 of the 4 species this record names. They are not the rules for South Fork Snake River (public access corridor). Per-water exceptions are the norm rather than the exception in every state here — special-regulation lakes, border waters, experimental reaches, in-season emergency closures — and any one of them overrides what is below.

Reading this water

Moving water. The read is about current first and depth second.

A river hands you the fish's problem for free: it has to hold somewhere it can eat without swimming hard all day. Find the places where fast water and slow water meet, and you have found where to start on most rivers, including ones you have never seen before.

Craft, not observation — this is the standing read for a river. It holds no clarity, temperature, level, flow, tide or hatch for this water today, and it does not name a spot.

Detail

Water section

Moving water. The read is about current first and depth second.

What this plate is telling you

Solid zones are features this class of water nearly always has. Dashed ones are the subtler reads — present often enough to look for, not often enough to assume.

Nothing here is an observation of today. No gauge reading, no clarity, no temperature and no fish went into this drawing. It is the same standing craft an angler carries between waters, and the water in front of you outranks all of it.

Plan view · where along the water

A reach of river, seen from above

One meander with the water moving left to right. Every river you will ever stand on is some version of this repeated — riffle, run, pool, tailout, and the bend that builds all four. It is a schematic of this class of water, not a survey of South Fork Snake River (public access corridor) — the shape of that particular shore is yours to read when you get there.

Nothing on this reach is doing anything unusual. That is a normal day, and normal days are read by walking rather than by diagram. Set a wind, a water state or a tide and the picture will move.

Water state

Tap a marked zone on the picture, or choose one by name above, for what it is, why fish relate to it, and how to find it standing there with no map. Nothing here says a fish is present — it says the physical reason that piece of water is worth a cast, and under which conditions that reason gets stronger or stops applying.

Decision flow

Four questions before the first cast

The drawing names features. This is the order that keeps them from becoming a scavenger hunt. Start with the force moving the water, find the shape that interrupts it, ask what changed, then verify the part the diagram cannot know today.

01Current02Bends + seams03Level / release04Gauge + bank

Where is the current doing less work?

Look for
Inside bend, eddy, bank edge, pocket behind structure.
Why it matters
A fish can hold close to the food lane without spending the same energy as the main flow.

Where does fast water touch slow water?

Look for
Bubble line, surface crease, edge of a riffle or tributary colour line.
Why it matters
That boundary is a feeding lane worth testing before the featureless middle.

Did the river move since the last read?

Look for
Rising colour, exposed gravel, new flooded edge, generation change.
Why it matters
The useful edge can move metres. The old answer may be physically gone.

When the water changes

It rained. They ran the dam. The wind swung.

Pick what actually happened. Nothing here reads a gauge — you supply the event, from your own eyes or the agency's page, and this says what it does to water of this class.

Still craft, not observation — this is what these changes do to a river. It does not know whether any of them happened here, and it never will. The agency's page and your own eyes are the only things that do.

Detail

What this record changes about the read

  • Current and flow are documented as a standing factor on this water. Read seams and current breaks first, and treat depth as the second question.
  • Cold-water species are documented here. Read for oxygen and temperature as much as for cover: broken water, inflows, shade and depth.
Current

Current seams

What it is
The line where fast water runs against slow — visible as a crease, a change in surface texture, or a trailing foam line.
Why fish hold there
A fish can sit in the slow side and let the fast side deliver food. It is the cheapest lie on the river, so it is usually the first one taken.
How to find it
Stand back and look across, not down. Seams show as a long straight edge in an otherwise broken surface, often below a riffle or beside an obstruction.
Depth

Riffle, run, pool, tailout

What it is
A river repeats the same four-part sequence: broken shallow riffle, deeper walking-pace run, slow deep pool, then a shallowing tailout at the pool's exit.
Why fish hold there
Each part holds fish for a different reason and at a different time of day. The run is the workhorse; the tailout and the head of the pool are the feeding stations.
How to find it
Walk the bank and name the parts before you fish anything. If you cannot name where you are standing, you are guessing.
Depth

Outside bends and cut banks

What it is
On a bend the current is thrown to the outside, which scours it deep and often undercuts the bank; the inside builds a shallow gravel point bar.
Why fish hold there
Depth, shade and an overhead lid in one place. On a bright day or in low water this is where the better fish are.
How to find it
Follow the bend with your eye: darker water and a hard bank line on the outside, pale gravel on the inside.
Current

Eddies and current breaks

What it is
Slack or reversed water behind a boulder, bridge pier, log jam, wing dam or point of bank.
Why fish hold there
A resting lie right beside a feeding lane. Fish move between the two rather than holding in the push all day.
How to find it
Look for the pillow of raised water upstream of the obstruction and the smooth pocket behind it. Fish the pillow as well as the pocket.
Edges

Tributary mouths and confluences

What it is
Where a creek or a side channel enters, bringing different temperature, clarity, oxygen and food.
Why fish hold there
A concentration point that works in almost every season, and a refuge when the main stem is high, warm or coloured.
How to find it
The colour or texture line downstream of the junction shows how far the incoming water carries before it mixes. Work that line.
Cover

Wood, undercuts and sweepers

What it is
Fallen trees, root wads, sweepers hanging into the flow and undercut banks held together by roots.
Why fish hold there
Overhead cover plus a current break. It is also the hardest water to fish cleanly, which is exactly why it holds fish.
How to find it
Read the current going into the wood, not the wood itself — the fish sits where the flow is broken, usually on the upstream or downstream edge, not in the tangle.
Depth

Depth changes and shelves

What it is
The lip at the head of a pool, a mid-river shelf, a gravel-to-bedrock transition, a dredged slot.
Why fish hold there
Fish use depth changes as travel routes and as ambush points. A one-foot change can matter as much as a ten-foot one.
How to find it
Polarised glasses and a low sun angle. Colour change on the bottom is the cheapest depth sounder there is.

Carry this water forward

You have answered where and what kind of water. Each instrument below answers the next question in the same workflow, and each link carries this record's water class, documented species, standing read, access position and declared job with it. Nothing is posted automatically, and no coordinates or private water travel in the handoff.

Narrow the handoff to one documented species (optional)

Species context is what the agency published for this water. It is never a statement that a fish is present today, or catchable.

    Field Sense Navigator — which water, what kind, what to look for and what still has to be checked today.

  2. 02SpeciesSpecies & PresentationWhich of these fish are actually worth planning around, and how do they behave here?4 species are documented on this record. Carry them across instead of retyping them.
  3. 03Forage & hatchHatch MatchWhat are they likely eating on this kind of water at this time of year?Moving water, so drift is the whole forage question. The water class and season go across with the record.
  4. 04Optional · device validationRig SignalDo the electronics or device claims hold under the conditions you actually stated?Current is documented here. If you are relying on electronics or a device claim, carry the water context over and test whether that claim survives moving water.
  5. 05TackleTackle Link AnalystDoes my line, leader and terminal tackle survive this water?Heavy current or traffic is on record; line and terminal choices have to survive it.
  6. 06KnotKnot AnalystWhich connection holds for this line class and this structure?The knot is usually where it lets go. Line class and the structure you are fishing decide which one to tie.
  7. 07Field opsField Ops DeskHow does this become a trip — travel, timing, kit and the checks still open?3 same-day checks still open, plus 2 named access sites. Turn it into a trip.
