Water-level Data

The District has 217 water-level gages on streams, channels, basins and dams throughout the Maricopa County region, measuring water depth and transmitting that data in real time. Using a rating relationship between depth and discharge, flow can be estimated from depth readings on streams. This information is available in different formats such as tables, maps and reports.
