INTRODUCTION HISTORY OF COLORADO RIVER BASIN DEVELOPMENT The Colorado River flows 2300 km about 1400 mi from the high mountain regions of Colorado through seven basin states to the Sea of Cortez in Mexico Figure 1 . The river supplies much of the water needs of seven . states two Mexican states and 34 Native American tribes. These represent a population of 25 million inhabitants with a projection of 38 million by the year 2020. Approximately 2 of the basin is in Mexico. The Colorado does not discharge a large volume of water. Because of the scale of impoundments and withdrawals relative to its flow the Colorado has been .
