USGS Water Watch- Current Water Resources Conditions DLESE Reviewed Collection
This interactive map depicts real-time steam flow compared to historical stream flow for selected gauging stations in the United States and Puerto Rico. Users may select a state and choose a list of all stations in the state, a state map, or a list of the nearest stations. The map tracks short-term changes (over several hours) in rivers and streams. Its appearance may change very little from one hour to the next, but individual sites may change rapidly in response to major rain events or reservoir releases. Colored symbols represent real-time stream flow as percentiles of historical stream flow for the day of the year.
