Run, flowing out of the hills behind Ben Lomond, a mile to the south. The combined stream then meanders through the bottomland before discharging into the Ohio, just above the mouth of Raccoon Creek on the opposite shore. Flatfoot Creek flows southeast out of the hills behind Hogsett, reaching the floodplain above Apple Grove, then running along the base of the hills north to Hogsett. Here the creek historically turned southward, and gradually meandered toward the Ohio, which it joined at the boundary of Clendenin and Hannan Districts. In the 1990s, part of the western portion of the floodplain along the Robert C. Byrd Locks and Dam was removed and flooded to build two auxiliary locks, and Flatfoot Creek diverted to empty into the Ohio at Hogsett. The original lower course of the creek was used to create a series of ponds below the locks. The Ohio Sixteenmile drains much of the southern part of the district. Its upper waters are in western Arbuckle District, along with its tributaries, the Wolfpen Branch and the Willow Branch, which join the main branch southeast of Arlee, along the district boundary. Sixteenmile curves around the base of Loggerhead Ridge, meeting the Loggerhead Fork, and flows south for about three miles past Potts Hollow and Potts Chapel Ridge, and meets the Righthand Fork flowing west from the hills near Sevenmile Ridge. From here, Sixteenmile flows west, meeting with Millstone Creek flowing from the north, and then turning southwest, meeting with Daves Run, and crossing into Hannan District. The creek makes a dogleg turn to the southeast, and briefly crosses back into Clendenin District, where it meets Jerrys Run, flowing westward, then continues southwest through Hannan District to the river. As it exits the hills, Sixteenmile is joined by Stonecoal Run, the upper waters of which are in Clendenin District. The main branch of Eighteenmile Creek only flows for a short distance through the southernmost part of Clendenin District, as it travels from western Putnam County to the Ohio River below Ashton in Hannan District. However, several of its tributaries flow out of Clendenin District, including the Spring Branch of Whitepine Creek, which joins Eighteenmile at the Putnam County line; Road Fork, all of which lies in Clendenin District; and the upper waters of Mud Run and the Hughes Branch of Eighteenmile. Other streams of Clendenin District include a Willow Branch that flows into the Ohio below Henderson; Mile Creek, which flows into the Ohio between Willow Branch and Salt Creek; Ohio Threemile, which enters the river opposite Gallipolis Island; Ferry Creek, of which several branches flow from the hills northeast of Gallipolis Ferry, and which joins the Ohio just above the old ferry landing; and the upper waters of the Kanawha Sixteenmile, or Big Sixteen, including its Fivefork Branch, drain the southeastern part of the district, before flowing into Arbuckle District. Communities Henderson is the only incorporated town in Clendenin District. It was first laid out by Frank Sisson in 1879, on land that had belonged to Samuel B. Henderson, one of the district's earliest settlers. Within a few years, it had its own post office, a general store, and about a dozen houses. The town developed around the intersection of two roads, one following the Ohio River northward to Point Pleasant, and one following the southern bank of the Kanawha. There was a ferry landing to carry passengers between Henderson, Point Pleasant, and Kanauga, a village in Gallia County opposite Point Pleasant. Since 1931, Henderson has stood at the southern end of a north-south bridge carrying traffic to Point Pleasant, and since 1969,
