This new growth from 2020 is also visible in the USGS chart above. Keep in mind that 2022 is not over yet.
"18 October, 2022. Mississippi River hits all-time low water record in Memphis
At 8 P.M. on Tuesday, October 18, the Mississippi River water level gauge in Memphis officially hit a new all-time low record water level of -10.79 feet.
Tuesday’s mark broke the previous cd low of -10.70 feet which was set on July 10, 1988.
"20 October, 2022. Mississippi River hits record low levels
Though the low level of the Mississipi this year is unprecedented in modern history, it’s normal, however, to see lower levels in the mighty river at this time of year, around areas such as Memphis. To be sure, during late summer and early fall, the waters can run low after hot and dry summers.
Previously, the low-level record at Memphis was at -10.7 feet on July 10, 1988. Later, two other record lows happened on August 30, 2006, and September 19, 2012.
The 2022 level of the Mississippi’s water is, significantly, the lowest anyone has seen since records began being kept in 1954."
I also decided to check and download data for the Mississippi River in the Memphis area. The result can be seen below, the river level has reached its lowest level ever! Data can be downloaded here:
