Cedar Creek flows through southeastern Iowa, traversing Jefferson, Van Buren, and Henry Counties as a tributary of Competine Creek. This waterway enters Jefferson County along its western border and flows southeasterly for approximately 25 miles through the county before continuing into Van Buren and Henry Counties. The creek exhibits characteristics distinct from larger southern Iowa rivers, featuring limestone outcroppings and a narrow channel that creates an intimate paddling environment.

The creek's history reflects significant human modification, having been channelized during the 1920s and 1930s throughout much of its length. However, the lower reaches—beginning approximately 1.5 miles past Turkey-Run Wildlife Area—have been allowed to revert to a more natural meandering course, offering paddlers a glimpse of the creek's original character.

Cedar Creek provides established paddling opportunities through Jefferson County, where the conservation board has developed a water trail system. Two documented point-to-point segments exist: Turkey Run Wildlife Area to Round Prairie Park covers 8.4 miles, while Round Prairie Park to Willow Road Bridge extends 8.1 miles and includes a 1.5-foot drop followed by a 20-yard riffle. This slow-moving creek requires active paddling to maintain reasonable progress, distinguishing it from faster-flowing rivers in the region.

The riparian corridor supports mature bottomland hardwoods including silver maple, sycamore, walnut, cottonwood, and river birch. The size of many trees, particularly the maples, indicates considerable age and provides substantial canopy coverage. This vegetation creates habitat for wildlife including wild turkey, deer, squirrels, and various bird species, particularly within the 405-acre Turkey Run Wildlife Area.

Access points include Turkey Run Wildlife Area (2747 Osage Ave, Fairfield) and Round Prairie Park, both managed by Jefferson County Conservation. These areas provide canoe and kayak access along with parking facilities. The creek connects three conservation areas: Cedar Creek Timber, Turkey-Run Wildlife Area, and Round Prairie Park.

Anglers find channel catfish common throughout the creek, with smallmouth bass present in rockier segments where limestone substrates provide suitable habitat.

Water levels fluctuate significantly throughout the year, making advance scouting essential before launching. The creek is designated as a protected stream in Henry County from its mouth to the west county line, and in Van Buren County for a short segment, reflecting recognition of its ecological value. Paddlers should expect occasional shallow conditions requiring portaging, particularly during low-water periods.
