Abstract
The preliminary results of a water balance study of a graminoid and low shrub fen at Minesing Swamp, Barrie, Ontario, Canada, are presented. The goal is to ultimately estimate each component of the water balance independently so the magnitude of the residual error can be evaluated. Neither channelized nor non-channelized surface flow occur during the monitoring season. Accurate estimates of the atmospheric components of the water balance have been made. Over the 1997 field season, precipitation contributed 402 mm and the evapotranspiration loss was 437 mm. The study area is a flow through system with an average horizontal ground water gradient of 0.002 m/m. In the vertical direction, small recharge gradients are measured within the study area on most occasions. Better estimates of the hydraulic conductivity of the peat are required to quantify the ground water contributions. Preliminary estimates of the change in storage over different time periods can be calculated from measured fluctuations in the water table and an estimated specific yield of 26% for the surface horizons of peat. Continuous monitoring of the water table will be implemented in the next study period and further hydraulic testing of the peat will be conducted to refine the specific yield and hydraulic conductivity estimates.
