The use of snow pillows for measuring solid precipitation in a prairie environment has been seriously questioned. However, our experience indicates that this gauging device can provide valuable information even under very unfavourable conditions such as: 1) Shallow snow packs (snow depth 20 inches) 2) Heavy drifting 3) Chinook areas 4) Isolated locationsComparisons of total catch under these conditions are made with Fischer & Porter, Belfort, Sacramento and Nipher precipitation gauges, and also with Standard snow course measurements. Guidelines for selecton of representative sites for precipitation gauges and snow courses under prairie conditions are presented. Snow pillow operational costs are also discussed.
