This dataset shows the recharge rate of the Châteauguay regional aquifer in mm/year. The data shown are the results of the estimated recharge of the regional aquifer using a water balance method based on (evapotranspiration, runoff, hypodermic runoff, recharge). Estimates were made using meteorological and river flow data available from 1960 to 2002. The mean annual recharge of the regional aquifer varies between 0 and 404 mm/yr from one place to another in the watershed.
This map was created to provide a regional frame of the spatial distribution of the recharge within the Chateauguay Aquifer.
