How waves are estimated

Significant wave height from the forecast hourly wind and the open-water distance (fetch) upwind, using the SMB method (US Army Corps of Engineers Shore Protection Manual, 1984), rounded up to the next 0.1 m. It is not a measurement: gusts, leftover swell and shoals can make water rougher. Under 0.2 m: calm; 0.2–0.5 m: choppy; over 0.5 m: rough.

Depth

18% of Norway Lake is deeper than 20 m.

How to read it: the lake’s area is sorted from the shore to the deepest point. Where the curve is flat, large areas share one depth (flats and weed beds); where it drops, depth changes quickly (drop-offs).

The government depth survey from 1971 records a maximum depth of 38.1 m, drawn from 32 depth contours.

Eating your catch

The provincial guide to eating fish (2026) sets limits for 4 species from Norway Lake. Maximum meals per month:

SpeciesLengthGeneral populationSensitive population*Contaminant
Largemouth Bass30-35 cm124Mercury
Northern Pike55-60 cm124Mercury
Smallmouth Bass35-40 cm84Mercury
Walleye40-45 cm124Mercury

* As defined in the guide, including children and people who are or may become pregnant. Limits are for the length the guide lists most often; they change with the size of the fish. Read the official guide

Fishing regulations: Fisheries Management Zone 15. Check seasons and limits before you fish.

Clarity was measured with a Secchi disk in 9 years between 1996 and 2004; the latest annual mean is 5.6 m.
