The "Law of the River," therefore, <br /> <br />represents a delicate balance of the competing purposes served by the <br /> <br />river system (i.e., flood control, water supply, power, recreation, <br /> <br />etc.) and the demands on the system's water supply amongst the seven <br />Basin States and the Republic of Mexico. <br /> <br />In 1983, an unusually heavy snow accumulation during May culminated a <br />rare hydrologic sequence which had already brought a near normal March 1 <br /> <br />snowpack to far above normal by May 1. The magnitude and timing of this <br /> <br />sequence were impossible to predict, and the end result was the flooding <br />which occurred on the Colorado River in 1983. As a result of this <br /> <br />flooding, suggestions have been brought forth by various segments of <br />Federal, State, and local Governments, and the public for reassessment <br /> <br />of the operation of the Colorado River. <br /> <br />1.2 Purpose and Objectives <br /> <br />~ <br />The purpose of this study is to ~~'l ~ the current operating strategy <br />of the Colorado River Basin ~ with alternate strategies <br />which attempt ,to reduce t~e risk of flooding and powerplant bypasses..
