An Assessment of the Groundwater Resources of Northern Ontario
Hydrogeology of Ontario Series (Report 2) AN ASSESSMENT OF THE GROUNDWATER RESOURCES OF NORTHERN ONTARIO AREAS DRAINING INTO HUDSON BAY, JAMES BAY AND UPPER OTTAWA RIVER BY S. N. SINGER AND C. K. CHENG ENVIRONMENTAL MONITORING AND REPORTING BRANCH MINISTRY OF THE ENVIRONMENT TORONTO ONTARIO 2002 KK PREFACE This report provides a regional assessment of the groundwater resources of areas draining into Hudson Bay, James Bay, and the Upper Ottawa River in northern Ontario in terms of the geologic conditions under which the groundwater flow systems operate. A hydrologic budget approach was used to assess precipitation, streamflow, baseflow, and potential and actual evapotranspiration in seven major basins in the study area on a monthly, annual and long-term basis. The report is intended to provide basic information that can be used for the wise management of the groundwater resources in the study area. Toronto, July 2002.
