Spread Creek EcoFlows Sites

Spread Creek streamflow monitoring sites.

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.
