June streamflow

More than 90% of the key index gaging stations across the country reported average to well-above average streamflows in June, and record-high flows were set on streams in Mississippi, Kansas, Nevada, and California, according to a month-end summary of water-resources conditions by the U.S. Geological Survey (USGS).

USGS hydrologists said that the unusually wet conditions were also evident in the combined flow of the three largest rivers in the lower 48 states—the Mississippi, St. Lawrence, and Columbia rivers—which averaged 5841 billion liters per day (bid) (1,298 billion gallons per day) during June, 49% above the long-term average. The combined flow of these major rivers has been above average now for 16 of the past 17 months. These three large river systems, which include the flow of the Missouri and Ohio rivers, account for runoff from more than half of the conterminous United States and provide a quick check on the status of the nation's surface-water resources.
