Topic: ottawa river rise and fall

Thanks Christian!
I've never actually checked that the gauge was in ft (at 45 degrees therefore x.707). Thanks for the confirmation.

Hi Adam.

Depends where. At Britannia, lowest can be around 57 m and highest around 59 m. So 6-7 feet let's say for yearly swing. At Mattawa, the level is nearly constant all year long, within 1 m. Below McKoys, the gauge swings from about -3 to about +24 feet on the gauge. But that gauge is at 45 degrees so the total swing there is about 70% of this range, so about 20 feet yearly. Elsewhere, I do not know for sure, someone else might pipe in. Hope this helps.

Does anyone know the actual physical rise and fall of the Ottawa river in ft?
