The One Hundred and Two River is a tributary of the Platte River in northwest Missouri. It originates in Nodaway County and flows generally southward for approximately 50 miles before joining the Platte River in Andrew County. The river's watershed drains portions of Nodaway and Andrew counties in the rolling hills of Missouri's glaciated plains region.

Paddling opportunities on the One Hundred and Two River are limited and best suited for experienced paddlers comfortable with flatwater conditions and potential obstacles. The river is relatively narrow and shallow in many sections, with a gentle current. Water levels can fluctuate significantly based on recent rainfall, so checking conditions before a trip is essential. The most commonly paddled section runs from near Maryville to the Saxton Access near St. Joseph, offering a casual float trip experience through rural Missouri farmland and wooded corridors. The difficulty is generally considered flatwater, though fallen trees and occasional riffles may be encountered, especially after high water events. Basic river reading skills and the ability to maneuver around obstacles are recommended. Late spring through early fall typically provides the best paddling conditions when water levels are moderate and temperatures are favorable.

Wildlife viewing opportunities abound along the river corridor. Paddlers may spot white-tailed deer, wild turkeys, various waterfowl, and occasionally river otters. The riparian zones support diverse plant communities, including stands of cottonwood, sycamore, and silver maple trees.

Key access points include: - Unknown location near Maryville (put-in) - Saxton Access near St. Joseph (take-out)

The river played a role in early settlement patterns of northwest Missouri, with several small communities established along its banks in the 19th century. Today, it primarily serves agricultural needs and provides recreational opportunities for local residents.

Safety considerations include checking water levels before trips, being prepared for weather changes, and watching for strainers or log jams. Missouri fishing regulations apply for those interested in angling opportunities. While most trips are done as day floats, primitive camping may be possible on gravel bars for those seeking multi-day adventures, though public lands are limited along the river corridor.

The One Hundred and Two River offers a peaceful paddling experience through a less-traveled portion of Missouri, providing a glimpse into the state's rural landscapes and natural beauty for those willing to explore its gentle waters.
