A high correlation was found between the precipitation that fell when soils were frozen (defined as the ‘cold period’) and the early spring runoff in eight of 10 watersheds in southern and central Minnesota. The cold period precipitation thus becomes a useful tool in predicting early spring runoff amounts in those areas where soils freeze. Results also indicated that cold period precipitation can be entirely accounted for by runoff and sublimation (or evaporation). Additions to the soil water reserves need not be called on to satisfy an accounting of the disposal of the ‘cold precipitation.’ This runoff prediction method has the advantage of simplicity once the linear regression equation for a watershed is calculated. The method requires only the measurement of soil temperature and precipitation at one station in each watershed.
