Temporal variations in snowmelt were investigated on an alpine snowfield in the Colorado Front Range. An area of approximately 8 ha collected snow in two large drifts, the upper reaching 12m in depth, the lower, 6m. Losses averaged 8m over the entire pack. Runoff was measured continously with a stage recorder. Total stream discharge was 3.9 x 10(8) m(3). The discharge hydrograph is examined at two sampling intervals, daily and hourly discharge totals. Flow is well described by low order autoregressive equations. There is a trend towards earlier peak flows and decreased lag times through the melt season.
