"For several years, water conservation has been espoused and implemented in various locations througout the country, largely in response to the drought in the West and partially as a political measure to provide new direction or emphasis in national water policy. Since the drough management measures were taken quickly and, by necessity, without supporting data, and since political uses of the concept required no corroboration, it appeared worthwhile to hold a conference of scientists and engineers to discuss the evidence available to recommend conservation and to identify the studies still needed to fill the remaining data and analytical needs." (from the Foreword).
