Season windows
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: BC Freshwater Fishing Regulations Synopsis 2025-2027, confirmed current. "Most waters in B.C. are open to fishing for some species 24 hours of the day, every day of the year", with five basic exceptions including year-round no-fishing areas listed in the Regional Tables. The structure is three tiers: General regulations, then Regional Regulations at the head of each of the nine regional chapters, then Water-Specific Tables which are exceptions or additions to those. No additional dated harvest closure applied beyond the MU table.

What's in this reading
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 this read cannot tell you
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
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.
Temperature
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 Howe Sound is doing today — put a thermometer in it and the drawing will show you where that number lands.
Stays on this device. It is not saved, not synced and not sent anywhere — this instrument has no account to attach it to.
Temperature
Preference and distribution mixed. A band for the species, not a forecast for Howe Sound.
What the edges are. No cold edge published. Warm edge: EPA short-term maximum. 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. Wismer & Christie 1987, GLFC Special Publication 87-3 (final preferenda from Coutant 1977a; growth optima from Jobling 1981 and Beltz et al. 1974). 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
Enter a water temperature above and the ceiling for this water appears on the curve.
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.
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 Howe Sound on any particular day. Agencies publish measured dissolved oxygen at many gauges — that number outranks everything on this drawing.

Reading this water
Coastal water is a clock as much as a place. The same mark is three different marks across a tide, so before you pick the mark, work out the window: which stage you want, and what the water will be doing then.
Craft, not observation — this is the standing read for a marine. It holds no clarity, temperature, level, flow, tide or hatch for this water today, and it does not name a spot.
Water section
A section through water of this class, near side on the left. It is craft, not a survey of Howe Sound — the shape of this particular bank is yours to read when you get there.
Not drawn: tide stage sets the terms. Those describe the whole system rather than a place in it, and putting them somewhere on this picture would be inventing a location to make it look fuller.
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
Beach, bar, trough and a rip, with an estuary mouth at one end. The tide is the current here, and it rearranges the whole picture twice a day. It is a schematic of this class of water, not a survey of Howe Sound — 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.
Tap the point the wind is coming from. The shore it is blowing onto is the one that collects the drift — and the one that is least pleasant to stand on.
Water state
Tide
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
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.
When the water changes
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 marine. 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.

Predictions cover the astronomical tide only. Wind, rainfall, runoff and pressure are not in the model, and CO-OPS names places where wind routinely puts the real water level a foot or two off the table. This is why you check the observed level on a windy day, not just the prediction.

A good model of how a state regulations system is built: an annual pamphlet of statewide rules, water-specific exceptions that override them, and an emergency rule feed that supersedes the printed pamphlet mid-season. That three-part shape is near-universal, so it teaches you what to go looking for in your own state.
