U.S. Geological Survey Streamflow Gaging

The Commission on Water Resource Management, along with various other government agencies, maintains an annual cooperative agreement with the U.S. Geological Survey (USGS) to establish and maintain continuous-record stations on streams throughout the State of Hawaii. The program began in 1909 when the USGS entered into an agreement with the Territory of Hawaii. Maintaining a long-term hydrologic monitoring program with the USGS is an essential component of the Commission’s mission to manage Hawaii’s water resources.

The link below will access the USGS’ listing of active streamflow gaging stations for Hawaii. The gages listed there are real-time and streamflow data can be found by clicking on each respective gage’s link. Gages in Hawaii are managed by the USGS Pacific Islands Water Science Center.
