Because some doubt has been expressed about the existence of true fresh discharge sloughs, three sloughs believed to have a discharge flow pattern were selected for detailed study in the Oak River Basin in southwestern Manitoba. The flow systems around each were investigated by installing piezometers and water table wells. In this manner it was discovered that a simultaneous inflow-outflow system (here termed throughflow) exists around each slough. In order to establish the relationship between the general groundwater flow system and the water level in the slough, comparative studies were made of slough recession and evaporation rates. It was discovered that net groundwater inflow occurs in two of the sloughs. Net groundwater outflow characterizes the third slough during the spring when evapotranspiration is at a minimum.All groundwa
