Scientists have been using both global and local technologies to monitor the amount of water in the Colorado River Basin. The technologies have helped government agencies to conclude that:
the amount of water in waterways is influenced by the presence of minerals dissolved in the water requiring more water purification plants
flood mitigation plans are needed because the amount of water in the Colorado River Basin is increasing at a slow rate
there was a cyclic trend to the amount of water in the Colorado River Basin between 2000 and 2022 therefore no new mitigation plans are needed
water conservation plans are needed because water levels in the rivers leading into Lake Mead are a major cause for the downward trend in lake surface elevation
