13.ABSTRACT (Maximum 200 words)
Lock and Dam 3 is located on the Red River, in a cutoff channel between 1967 river miles 140 and 142, and about
53 channel miles above J ohn H. Overton Lock and Dam. The lock and dam will be the third lock in a series of five locks and
dams des igned to furnish the required maximum lift of 141 ft to provide year-round navigation on the Old and Red River
Waterway from the Mis siss ippi River to Shreveport, LA, a distance of 236 miles . The principal structures are an 84-ft-wide
by 685-ft-long lock, a s pillway containing six 60-ft-wide by 42-ft-high tainter gates, and a 315-ft-long fixed-crest weir
adjacent to the gated spillway. The dam provides a navigation pool that extends upstream to Lock and Dam 4. The dam is
operated to maintain a navigation pool of el 95.0 at the dam (all elevations (el) cited herein are in feet referred to the National
Geodetic Vertical Datum). A fixed-bed model reproduced about 3.5 miles of the Red River and adjacent overbank from
about 13,500 ft upstream to about 4,800 ft downstream of the dam to an undistorted scale of 1:100.
Since Lock and Dam 3 was to be constructed in an excavated channel bypass ing the natural river channel, it was important
that the alignment of the channel and the arrangement of the lock and dam be satisfactory for navigation. The model
investigation was concerned with evaluation of navigation conditions for proposed lock designs and development of
modifications required to ensure satisfactory navigation conditions. The study identified any needed modifications to the
