The prediction of the Missouri River flowing into Fort Peck Reservoir presents many problems where the reservoir is 225 miles east of the nearest snow survey course. The river transverses an entirely different environment from the headwaters basins. Many unmeasured diversions are encountered as well as unmeasured tributary streams. Precipitation data appeared to show a better relation to percent normal than the snow survey data, probably due to the remote location of the reservoir and the large area in the rain fall altitudes. In order to produce a more reliable forecast from snow surveys a longer record of data is needed and considerable study will be necessary.
