Welcome to the NWIS-Web for the Arizona Water Science Center

The majority of USGS Gaging Stations are funded though a cooperative program between the USGS other interested agencies.

Daily Streamflow Conditions

Stream gage levels in Arizona, relative to 30 year average.

Explanation
	High
	> 90th percentile
	76th - 90th percentile
	25th - 75th percentile
	10th - 24th percentile
	< 10th percentile
	Low
	Not ranked

The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.

The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

Statewide Streamflow Table

Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from current sites are relayed to USGS offices via satellite, telephone, and/or radio telemetry and are available for viewing within minutes of arrival.

All real-time data are provisional and subject to revision.
