Thousand Islands River : study of solutions to address critically low water levels : summary report; Riviere des Milles Iles : etude des solutions de soutien des etiages critiques : rapport sommaire

Abstract

A study was conducted to find solutions to very low water flow in the Thousand Islands River, near the Island of Montreal, Quebec. It was launched in response to the critically low water levels that were experienced in 2001 and 2002. In the summer of 2001, municipalities served by the Thousand Island River were faced with problems in the supply of drinking water when the river flow reached approximately 13 cubic metres per second. Since 1970, the minimal values of flow observed for this time of year had seldom passed under 20 cubic metres per second. Under such conditions of flow, the dilution of any water discharged into the river became so weak that the aging water treatment facilities had to work beyond their capacity. In addition, the population served by this river has increased significantly in the past 2 decades. During this episode of critically low water levels, Quebec's Center of Water Expertise (CEHQ)intervened in an emergency measure to drain flows from a water reservoir in the catchment area to ensure a minimal flow of approximately 25 cubic metres per second. Thereafter, the affected municipalities had to ask the Quebec Environment Ministry to define permanent interventions to ensure a  More>>

The CEHQ carried out a preliminary study of possible solutions to address the critically low water levels and presented its report in the spring 2002. In the winter of 2002, CEHQ created an emergency management procedure in preparation of a repeat episode. 28 refs., 11 figs.}
