Mississippi River Watershed Receives a Grade of C-

America’s Watershed Initiative (AWI) released its second Mississippi River Watershed Report Card, resulting in a grade of C- for the entire watershed, which covers more than 41 percent of the continental United States and 31 states.

The Mississippi River Watershed Report Card brings together data from multiple sectors and basins, allowing an examination of the status and trends in the watershed. The report card measures the health of the Mississippi River Watershed across six goal areas: water quality and ecosystems; flood control and flood risk management; recreation; transportation; economy, and; water supply.

The Report Card also grades the five major sub-basins—the Upper Mississippi River, Lower Mississippi River, the Ohio and Tennessee Rivers, the Arkansas and Red Rivers, the Missouri River. AWI last prepared a Mississippi River Watershed Report Card in 2015, resulting in a grade of D+. Despite some modest improvements, the watershed remains threatened by more frequent and extreme flooding, aging infrastructure, chemical pollution, nutrient runoff and continued urbanization and agricultural intensification. 

Without this, it’s too difficult to know whether we’re making a difference at the scale of the Mississippi River.

“The Mississippi River Watershed, which shapes thousands of communities and powers the nation, faces pressing challenges, with significant implications for the health and safety of all Americans, as well as our economy,” said Kimberly Lutz, Executive Director of America’s Watershed Initiative. “As the United States looks to recover and rebuild our economy amid the coronavirus pandemic, the health and resilience of this critical natural resource—through investments in infrastructure, research, education and flood and water management—must be part of the solution.”

Michael Reuter, who serves as the U.S. Midwest director for TNC and who played a key role in launching AWI, said a national investment in scientific data is necessary to inform the management of the massive Mississippi River watershed. “Without this, it’s too difficult to know whether we’re making a difference at the scale of the Mississippi River. Without consistent standards and funding to measure water quality, flooding and more, we are driving our best car without regularly checking the oil or kicking the tires.”
