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

42% of Lac Stevens is deeper than 5 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 1961 records a maximum depth of 15.8 m, drawn from 27 depth contours.

Water

Trophic status from the latest monitoring: oligotrophic.

Clarity was measured with a Secchi disk in 17 years between 2008 and 2025; the latest annual mean is 4.2 m.
