Abstract: A series of curves were developed which can be used to forecast the date of ice formation at 1 bay, 10 lake and 17 river locations in Canada. The numerical constants necessary to develop these curves were obtained from a relationship between mean daily air temperatures and previously observed dates of ice formation. Two ice formation periods are considered: 1) first appearance of ice in the fall; and 2) the date of complete ice coverage. For 19 stations, however, numerical constants and forecast curves are derived for only one of the periods because of insufficient data. To apply the curves, an adjusted temperature record, based on a numerical constant (N) and daily air temperatures, is maintained starting in early summer. Subsequently, this daily-adjusted temperature is applied to the family of curves to provide a day-to-day forecast of the date of ice formation. The procedure is discussed in detail, using Fort Good Hope as an example.
