The mighty Mississippi, which flows from its headwaters in northern Minnesota to the Gulf of Mexico, has topped an endangered rivers list.

A report from nonprofit conservation organization American Rivers states that a combination of extreme flood, drought cycles, toxic runoff, and poor river management threatens the Mississippi. The 2,300-mile-long river is a water source for more than 50 cities in the U.S., including several in Minnesota.

Cuts to the Federal Emergency Management Agency (better known as FEMA) are also a concern.

“There's just a lot of questions about what's going to happen to that agency,” said MPR News correspondent Kirsti Marohn​. “FEMA plays a role in reducing flood risks and supporting resilient development in communities along the river, and then also helping communities prepare for disasters and recover from them.”

Marohn covers central Minnesota communities, water and the environment. She joined MPR News chief meteorologist Paul Huttner to explain the threats the river is facing.
