Earthquakes struck New Madrid,Missouri during the winter of 1811-1812 and changed the course of what?
Probably a river. What river is nearby?
Im not sure im trying to find it on google and can't find the right one

Read through SEVERAL of the links in there until you find it.
As Writeacher suggested, look at the closest major river in this region.

IT could be several rivers like the Mississippi River the Missouri River the Ohio River, and maybe even the Colorodo River
The earthquakes that struck New Madrid, Missouri during the winter of 1811-1812 were a series of powerful seismic events that have been historically significant. They had a profound impact on the region, and one of the notable effects was a significant change in the course of the Mississippi River.
To understand how the earthquakes changed the course of the Mississippi River, it is important to recognize the geological processes involved. The New Madrid earthquakes were caused by the movement along the New Madrid Fault System, which stretches across parts of Missouri, Arkansas, Tennessee, and Kentucky. These earthquakes were some of the most powerful to ever hit the contiguous United States and are estimated to be between magnitude 7 and 8.
The powerful shaking caused by the earthquakes had several repercussions. One of the most significant effects was the formation of temporary land uplifts known as "earthquake domes" in the region. These uplifts created new barriers across the Mississippi River, leading to the rerouting of the river's course.
The force of the earthquakes caused the earth to uplift near the town of New Madrid, effectively damming the Mississippi River in multiple locations. As a result, the river deviated from its original course and created new channels. The river flowed backwards for a short period, creating what is now called "Reelfoot Lake" in Tennessee. Over time, the river gradually established its new course and abandoned some of the old river channels.
The changes in the Mississippi River's course disrupted navigation routes and affected transportation and settlements in the region. The earthquakes also caused other significant geological changes, such as the formation of new sand blows, landslides, and additional geological features.
In summary, the earthquakes that struck New Madrid, Missouri during the winter of 1811-1812 changed the course of the Mississippi River by creating temporary uplifts and barriers, leading to the formation of new channels and the abandonment of old ones.
