Flow Report - UNITED STATES

March 18 2024

Rivers across the nation are experiencing a mix of swollen waters and high streamflows, posing various challenges and opportunities for communities and outdoor enthusiasts. Recent data indicates that the Mississippi and Ohio Rivers, vital waterways for commerce and recreation, have reported significantly high streamflows, with the Mississippi River at Vicksburg, Mississippi, hitting a streamflow of 686,000 cubic feet per second (cfs) amid showers and the Ohio River at Old Shawneetown, Illinois-Kentucky, reaching 361,000 cfs in sunny conditions. Cities such as Memphis, Tennessee, and Greenup, Kentucky, along these rivers may need to brace for impacts on infrastructure and water management.

Streamgauges in watersheds like the Middle Tombigbee-Lubbub and the Lower Ocmulgee have indicated flows up to 329% above normal, which are critical for researchers monitoring ecological health and water supplies. With various regions receiving heavy rainfall, the Wax Lake Outlet at Calumet, Louisiana, and the Apalachicola River near Sumatra, Florida, are also swelling, affecting not just water levels but potentially altering fishing and rafting conditions. Seasonal outdoor activities along the Willamette River at Portland, Oregon, and the Connecticut River in Connecticut could see increased water levels, with implications for boating and wildlife observation.

As the data reflects, the landscape of America's rivers is dynamic, with certain areas like the Buttahatchee River and the Santee River observing streamflows nearly double their normal levels, while the Flint River in Georgia is flowing at over 250% of its average. Conversely, regions such as the Strait of Georgia and the Duwamish are below their typical flow rates, indicating potential drought conditions that could impact water conservation strategies. For river enthusiasts and professionals alike, these fluctuating conditions underscore the importance of adaptive water management and the need to stay informed about changing river conditions that affect both local communities and the broader environmental landscape.

What is a Streamgage?

Surface flow data in the US is crucial for managing our water resources sustainably. Thousands of streamgages across the nation provide vital insight for understanding hydrological patterns, forecasting floods and droughts, and guiding water management decisions. But what is a streamgage exactly?


Strong El Nino Climate Pattern

Oceanic Nino Index

The Oceanic Niño Index (ONI) is a rolling 3-month average temperature anomaly, and used for tracking El Niño-Southern Oscillation climate patterns. Based on the latest data for the last 3 months (DJF), the Oceanic Nino Index is currently 1.8, signifying a strong El Nino period. A persistent above average sea surface temperature may signify an El Niño episode. Conversely, a below average sea surface temperature will signal the onset of La Nina occurences.

Some notable tributaries with traditionally high stream flow include the mighty Mississippi, the iconic Colorado, and the scenic Columbia. In addition, there are numerous reservoirs and dams across the country that play a pivotal role in water storage and distribution. Understanding surface flow data is critical for ensuring water security and supporting sustainable development.
