Abstract

The fall flow of a stream is an indication of the soil moisture content over the entire watershed. A correction based on October, November and December flow in acre feet has been applied to the April 1 water content of the snow. This procedure is applied to many streams in Wyoming, Colorado and New Mexico to improve the accuracy of runoff forecasts. A graph is used to illustrate that the introduction of the fall-flow factor tends to produce a smoother curve than with snow survey data only plotted against runoff.Discussion by G.B. Jacobson.
