Real-time Data

Our scientists gather information through periodic or continuous measurement in the field to provide a view of current conditions. In some instances, observations may not be subject to rigorous review before release; this will be noted in the documentation accompanying the data.

California Wildfires

Wildfires pose significant threat in an increasingly arid California landscape, threatening life, property, and air quality, and having long-term impacts on the state's water. Knowing the location and extent of wildfires may help scientists and resource managers predict and manage potential impacts burns may have upon California's water quality, availability, and movement.

WaterWatch (surface water)

WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including flood and droughts. Real-time information generally is updated on an hourly basis.

WaterNow

The USGS WaterNow service lets users receive current conditions for USGS water-data-collection stations on demand via email or cell-phone text message. The user sends an email or text message containing a USGS current-conditions gaging site number, and will quickly receive a reply with the station's most recent data for one or more of its monitored parameters.
