Lamoille Creek Basin normals: A case in which extension of normals by comparison with precipitation-data proved more valuable than by comparison with another stream
Normals for snow-courses having only a few years record, can be computed by expanding the mean for the period of record by comparison with precipitation, runoff, or an adjacent snow-course for which longer records are available. Those of runoff may be expanded by comparison with precipitation, snow-cover, or with the runoff of an adjacent stream. In the future, tree-ring studies will probably play an important role in the expansion of normals.In this paper a case is exemplified in which the snow-cover normal was created by comparison to precipitation, and the stream-flow mean was likewise expanded after the available records were carefully analyzed. No special study was made to select a certain case for this paper. A system of normals was wanted for Lamoille Creek in eastern Nevada and therefore this stream was selected for the study here given.
