The Missouri River is one of the longest, and one of the most important rivers in the United States. This river passes through multiple states, starting from Montana and ending at the border between Missouri and Illinois where it enters the Mississippi River. Considering the length of this river, it is nothing unusual that it has lot of tributaries, some of which large, some small. The largest tributaries of the Missouri River are the Osage, Cheyenne, Kansas, Platte, Niobrara, and Yellowstone rivers, all coming from southern and western direction, while the James and Milk rivers are coming from northern direction.
All these tributaries make the river and the settlements around it to be well connected deep into the interior of the country, providing easy transport and travel. This river, together with its larger tributaries is crucial for the agriculture in this part of the country, as the majority of the water used for irrigation comes from their waters.
