Here flows the Platte River. The Platte River is more than just a body of water. It is a story etched in time.
The Platte River is a major American river in Nebraska. It stretches about 310 miles long. Measured to its farthest source via its tributary, the North Platte River, it flows for over 1050 miles. The Platte River flows into the Missouri River. The Missouri itself flows into the Mississippi River. Finally, the Mississippi reaches the Gulf of Mexico.
French explorers and fur trappers first saw the Platte around 1714. They called it the Nebraskier. This was a transliteration of the name the Otoe people gave it. It meant flat water. This is very close to the French words rivière platte or flat river. This likely gave the Platte River its name.
The Platte River forms in western Nebraska. It is east of North Platte, Nebraska. The North Platte and South Platte Rivers join here. Both originate from snowmelt in the eastern Rockies. They are east of the Continental Divide.
The North Platte River starts in north-central Colorado. It is in the North Park valley. Mountains of 12000 feet surround this valley. The North Platte River’s head is essentially all of Jackson County. The Continental Divide borders it on the west and south. Mountain drainage peaks border it on the east. Wyoming forms its northern boundary. Walden is the nearest Colorado town and the county seat. The North Platte flows north about 200 miles out of the Routt National Forest and North Park. It passes near Walden to Casper, Wyoming. After Casper, the North Platte turns east-southeast. It flows about 350 miles to North Platte, Nebraska.
The South Platte River’s drainage includes about 28000 square miles. This covers northeast Colorado, parts of southeast Wyoming near Cheyenne, and a small part of southwest Nebraska. The South Platte drains much of the Front Range mountains east of the Continental Divide. The South Platte forms in Park County, Colorado. This is southwest of Denver in the South Park grassland basin. It is created by the confluence of the South Fork South Platte River and Middle Fork South Platte River. This is about 15 miles southeast of Fairplay, Colorado.
After the North Platte and South Platte rivers merge, the Platte River becomes a sandy, broad, shallow, braided river. Its many shallow channels, islands, and ever-changing sandbars made navigation hard. It was never a major water transportation route. The Platte flows in a large arc. It goes east-southeast to near Fort Kearny. Then, it turns east-northeast across Nebraska, south of Grand Island, and on to Columbus.
The Loup River joins the Platte River from the north. This happens about 2 miles southeast of Columbus. The Elkhorn River joins the Platte on its southbound path. This is southwest of Omaha. The Platte-Missouri River confluence is about 10 miles south of Omaha.
Including the North Platte River, the Platte River stretches over 850 miles. Its drainage basin covers about 90000 square miles. The Platte drains an arid area of the Great Plains. Its flow is much lower than other rivers of similar length in North America. It is a classic wide, muddy, and shallow braided stream. In its lower reaches, it flows in a floodplain bordered by bluffs.
The Platte River valley was a wagon corridor. It sloped gradually upward from the Missouri. The Platte route offered water, grass, buffalo, and buffalo chips for fuel. Native American trails existed on both sides of the wide Platte River. The water was silty and bad tasting but usable. Emigrants let it sit to settle the silt. The trails through the Platte River Valley extended about 450 miles in Nebraska.
Many of Nebraska’s larger cities started on or near the Platte River. These include Omaha, Fort Kearny, Grand Island, and North Platte.
The Platte is in the middle of the Central Flyway. This is a primary north-south corridor for migratory birds.
Since the mid-20th century, the Platte River has shrunk significantly. This is due to irrigation and water diversion for Colorado’s growing population. The Platte River’s story is one of adaptation and resilience. It is a lifeline in an ever-changing world.
