in 1922, the same year it was signed. Colorado River Compact was signed by the delegates from the seven Colorado River Basin states: Wyoming, Colorado, Utah and New Mexico were designated Upper Basin states and California, Arizona and Nevada as the Lower Basin states. This compact determined that the water would be shared equally among the upper and lower basin states. Prior to the compact, the name of the river was standardized along its length. Previously the portion of the river upstream from its confluence with the Green River had been known locally as the "Grand River". The change was opposed by many local residents in Utah and Colorado, and the new name was enforced locally by acts of the state legislatures in both states in the early 1920s. One of the major concerns both today and back in the 1920s was the expanding population, and this increased the demand for water, particularly in California. In more recent years, mainly because of Las Vegas, Nevada has been looking for more use of the Colorado River. In 1934, Arizona, unhappy with California's decision to dam and divert the river, called out the National Guard and even commissioned a two-boat "navy." The matter was eventually settled in court. The agreement was controversial even at the time, however. Arizona, for example, was dissatisfied with the lower basin allotment. Led by Fred Colter, the state refused to sign the agreement, and did not do so until two months after Colter's death in 1944. The specific allotments were disputed by Arizona until the United States Supreme Court upheld the amount in the 1963 decision in Arizona v. California. The agreement ended many years of dispute, clearing the way for the Central Arizona Project, authorized by Congress in 1968 – though the Supreme Court has been asked to readjust Arizona's water allocation a half-dozen times in the interim. Mexico was able to gain some of the river rights, and Arizona took steps as well to protect its water rights and keep California from gaining too large of a share, which ultimately led to the Arizona v. California Supreme Court case. The case lasted 11 years and cost over $5 million, requiring the work product of over 50 lawyers. Based on an assumption that California was using more than its contractually allotted water amount, Arizona set the precedent of the Supreme Court using water rights. The case
