Book Description
McAlpine Locks and Dam are on the Ohio River at the northwestern end of Louisville, KY, 606.8 miles below Pittsburgh, PA. The structures, including the dam, the canal, and locks, extend from mile 604.4 to mile 607.4. The upper pool of the dam extends approximately 75 miles upstream to Markland Locks and Dam near Warsaw, KY. The provisional plan recommended in the McAlpine Navigation Feasibility Report consists of constructing an additional 110 by 1,200 ft. lock in place of the existing auxiliary chamber. This would result in two locks 110 ft. wide by 1,200 ft. long. The new lock would be parallel to the existing 1,200 ft. lock, with the upper gates in approximately the same location as the existing lock upper gate. A guide wall would extend upstream 1,275 ft. beyond the upper miter gate monolith and tie into the existing canal wall. A south guide wall would extend 1,200 ft beyond the lower miter gate monolith. A fixed bed model reproduced the Louisville and Portland Canal, the existing locks, a limited section of the Ohio River immediately upstream of the canal, that part of the river channel between Shippingport Island and the fixed crest weir connecting the upper and lower spillways, and the lower approach to the locks at an undistorted scale of 1:80. Upstream of the lower spillway, the right descending model limits followed the alignment of the fixed crest weir from the upper gated spillway to the lower gated spillway. However, as the model would not be reproducing any river flows that would create flow over the fixed crest weir, the crest elevation of the weir was not reproduced in the model. The general design of the new 1,200 ft. long lock was complicated by its proximity to the existing 1,200 ft. lock, its placement at the downstream end of a long approach canal, and the restricted area downstream of the lock available for lock discharge laterals.

Book Description
McAlpine Locks and Dam are located on the Ohio River near Louisville, Kentucky, 606.8 miles below Pittsburgh, Pennsylvania. The locks are located in a bypass canal on the left overbank landward of Shippingport Island. A powerhouse is located along the left bank adjacent to the downstream end of Shippingport Island, and a four-gated spillway section is located adjacent to the powerhouse. A fixed-crest weir extends for the four-gated spillway section upstream 6,600 ft generally parallel to the right band to an upper five-gated spillway section which is connected to the right bank with a 1,200-ft-long fixed-crest weir just upstream of the Pennsylvania Railroad bridge. The structures, designed to maintain a minimum upper pool during low flows extending about 75 miles upstream to Markland Locks and Dam near Warsaw, Kentucky, include a navigation lock with clear chambers dimensions of 110 ft wide by 1,200 ft long located at the lower end of a 1.75-mile-long canal along the left bank and two auxiliary locks between the main lock and left bank that are out of service. A fixed-bed model reproduced about 8.5 miles of the Ohio River channel, the lock approach canal, and adjacent overbank areas to an undistorted scale of 1:120.

Book Description
Since the early 1800s, people have made a living fishing and harvesting mussels in the lower Ohio Valley. These river folk are conscious of an occupational and social identity separate from those who earn their living from the land. Sustained by a shared love of the river, deriving joy from the beauty of their chosen environment, and feeling great pride in their ability to subsist on its wild resources and to master the skills required to make a living from it, many still identify with the nomadic houseboat-dwelling subculture that flourished on the river from the early nineteenth century to the 1950s. Today's community of fisherfolk is small and economically marginal, but their activities sustain a complex set of traditional skills and a body of verbal folklore associated with river life. In Flatheads and Spoonies, Jens Lund describes the activities, boats, gear, verbal lore, and sense of identity of the fisher folk of the lower Ohio River Valley and provides historical and ethnobiological background for their way of life. Lund connects the importance of river fish in the diet of inhabitants of the valley to local fishing activities and explores the relationship between river people and those whose culture is primarily land-based, painting a colorful portrait of river fishing and river life. This book offers a look—historical and ethnographic—at a little-known aspect of traditional life in the American Midwest, still surviving today despite immense changes in environment, resources, and economic base.
