The Ronald B. Robie papers consist of files and documents assembled by Robie during his years with the Assembly Committee on Water, the State Water Resources Control Board, and the California Department of Water Resources. The collection contains materials whose dates span from 1963-1982; the majority, however, are concentrated in the period from 1967-1979.

The collection consists primarily of speeches by Warne during his tenure as Director of the California Dept. of Water Resources, 1961-1966; also includes miscellaneous correspondence and articles written by Warne during this period.
