Has the Mississippi river ever dried up before now?
The worst-ever dry period occurred in the late 1500s. However, the dry years of 2021 and 2022 exceeded the 1500's drought length. This means the last 22 years are the driest in 1,200 years.

Before 2022, the last time the river experienced such a severe drought was a decade prior. Despite the improved conditions, more precipitation is needed before the river reaches above average levels. The elevation is average and below average depending on which gauge along the river system, Parker said.
The Colorado River is drying up due to a combination of chronic overuse of water resources and a historic drought. The dry period has lasted more than two decades, spurred by a warming climate primarily due to humans burning fossil fuels.
Seven states and 30 Native American tribes lie in the Colorado River Basin. As we first reported in 2021, the river has been running dry due to the historically severe drought. The majestic, meandering Colorado River that cut through these red cliffs, carving the Grand Canyon, is a wonder of nature and human ingenuity.
As crazy as it sounds, engineers say the idea is technically feasible. It would involve building a system of dams and pipelines to move the water uphill across multiple states over the Continental Divide. Gravity would then work in our favor to drop the water down to the Colorado River watershed.
The drought crisis that grounded barges and unearthed fossils may finally be over. The US Army Corps of Engineers has been dredging the Mississippi River 24/7 since July. Drought along the Mississippi has dropped water levels to lows that haven't been seen in a decade.
Levels are rising now but to a point where it may introduce other complicating factors. Water levels along the Mississippi River near Memphis are more than 21 feet, which is nearly a foot higher than where they were in April 2023, according to the U.S. Geological Survey.
Over the years, a proposed solution has come up again and again: large-scale water diversions, including pumping Mississippi River water to the parched west.
Hoover Dam, a concrete-arch gravity dam, captures water from the Colorado River and fills Lake Mead. At capacity (1,221.4 feet above sea level), the lake is the nation's largest reservoir, able to contain 28.9 million acre-feet of water covering about 248 square miles.
Since 1983, years of drought along with high water demand have caused the lake to drop by 132 feet. Today, the lake is at only 30% capacity, its lowest level since it was built in the 1930s. Fortunately, heavy rainfall early in 2023 has relieved the situation a little, but only temporarily.
Colorado River crisis is so bad, lakes Mead and Powell are unlikely to refill in our lifetimes. Boaters are dwarfed by a white bathtub ring around Lake Mead.
Right now, there is only about 7 million acre-feet flowing into the Canyon in 2022. But levels are still declining, and we are getting closer to the point where Glen Canyon Dam cannot generate electricity, and potentially even worse, where water really can't safely flow through the dam at all.
