"The Town of Hay River, N.W.T., is situated at the mouth of the Hay River on the south shore of Great Slave Lake. A significant portion of the Town is located on the low-lying land of the Hay River delta and is subject to severe ice jam floods every decade or so. The most recent was in 1985, when an ice jam flood that exceeded the designated flood risk elevation occurred suddenly, with significant risk to life. As a first line of defence against a repetition of such an event, it was proposed that the ice jam flood forecast procedure traditionally undertaken by the Town be formalized and, if possible, refined. To do this the present two-phase study was commissioned. This report presents the results of the first phase"--Summary. Flood forecasting Northwest Territories Hay River.
