How much has Lake Powell fluctuated since 1963?
Lake Powell reached its full capacity for the first time in 1980, 17 years after the completion of Glen Canyon Dam. Since 2000, shrinking snowpacks, rising temperatures, thirsty crops, and growing populations have strained the Colorado River and its reservoirs Lake Powell and Lake Mead. See the graph below.
