demand for recreation increased the need for multiple-use planning. The Multiple-Use Sustained-Yield Act of 1960 for the first time established recreation as well as wildlife as an equal priority for the Forest Service with range, timber, and watershed oversight. The Park Service took a utilitarian approach to its recreation areas, acknowledging their less-than-national significance and focused on providing useful facilities and allowing a wider range of activities. Through the 1950s, many traditionalists at the NPS saw recreation areas championed by Wirth as distractions with open questions of how to manage and square them with the broader aims of the agency. As increased visitation forced answers to these, Lake Mead served as a model for administration at other recreational units, experiencing changing demands of the public, with more day-use visitors. Wirth advocated for changing the Lake Mead's designation to "national recreation park," which would emphasize its importance with autonomy from the USBR. His Mission 66 vision provided capital investment for construction of visitor services and infrastructure across the park system. Standardization and expansion In 1963, the Recreation Advisory Council, created by executive order of President John F. Kennedy and composed of five major government officials, issued a policy that recognized the need for and established criteria for establishing NRAs. The council recommended that NRAs should focus on growing "recreation demand" more than preservation, conservation, or development; have significant natural and recreational quality greater than that of state lands, even if not as unique as other parts of the National Park System; and provide opportunity for recreation consistent with other federal public lands programs. It outlined seven mandatory criteria and six secondary criteria for establishing NRAs, including a minimum size, ability to attract a significant number of visitors from nearby and beyond its state, and filling a regional need with recreation as the dominant purpose. The policy also called for national recreation areas to be established by acts of Congress and for them to be able to be managed by multiple agencies as necessary, including as partnerships with states. The Bureau of Outdoor Recreation (rather than the NPS) was charged with studying proposals and referring them to the council for recommendation. This process gave flexibility to the NPS and USFS to develop their own guidelines for unmet future recreational needs. In response Congress made Lake Mead National Recreation Area the first such area to be established by statute in October 1964, finally
