How much water is in Lake Powell? The water level in Lake Powell depends on how much water comes in from river flows, and how much water goes out every year. This graph shows total monthly inflow into Lake Powell for the months of May, June, and July from 2000-2023. The black line shows how full Lake Powell was as a percentage of total capacity.
