白河 1 号船闸和大坝（LIHI #179）, 2号船闸和大坝（LIHI #180）, and the “Shelby M. Knight” Lock and Dam No. 3 Hydroelectric Projects (LD1, LD2, LD3) collectively known as the “White River Hydroelectric Project”, are located on the White River in north central Arkansas. The river begins in northwestern Arkansas in the Boston Mountains and flows east toward Fayetteville where it then turns north. The river enters Missouri near Eureka Springs. It then flows southeast back into Arkansas past Bull Shoals, Mountain Home, and Calico Rock. At Batesville, the second section of the river, known as the Lower White, begins. From Batesville, the river flows south for 295 miles through Arkansas’s Delta region before emptying into the Mississippi River. The river passes multiple lakes created by eight USACE dams. Six lakes are operated together as a system to reduce the frequency and severity of floods.
Between 1900 and 1908, USACE built the three timber-crib and concrete dams and locks associated with the Projects. The locks were used for navigation, moving boats containing shipments of timber, cotton, and mining products such as limestone and silica. By the mid-1950s, trains had replaced boats as the primary method for transporting these products. USACE decommissioned the locks and sold the properties. Development of the new hydropower capacity involved a utility, a college, a city, a county, the U.S. Congress, 27 years, a myriad of engineers and lawyers, and lots of tenacity and perseverance by a dedicated group of individuals. Project construction began in 2003 and the Projects came online in 2006-2007. LD3 is the most upstream of the three Projects located in Stone County, AR at river mile 320.2.
LD3 includes a concrete and 木制婴儿床 坝 approximately 750 feet long and 21feet high with a 3-foot-high concrete cap added in 2010 that raised the dam height to a 泄洪道 crest elevation of 275.5 feet (胃肠疾病).
The dam creates an impoundment with a surface area of 787 acres. The 发电站 contains a single vertical Kaplan turbine and generating unit rated at 4.3 MW with a design flow of 3,163 cubic feet per second (cfs). The average annual generation is approximately18,700 MWh. An open-水槽 tailrace returns flow to the river 300 feet downstream of the dam. The Project boundary encompasses the high-water mark and about 42 acres of land around Project structures.
该项目以瞬时 径流 mode. Inflows for LD1, LD2 and LD3 are dependent on the outflow from the upstream USACE dams at Bull Shoals on the White River and from Norfolk Lake on the North Fork River along with other tributaries. There are no spillway 门 在任何一座水坝。与河流流量相比，工厂流量较低，蓄水水位很少下降到或低于 泄洪道. 径流式 根据阿肯色州贝茨维尔白河沿岸的美国地质调查局测量仪对运行和流量进行监测。
这三个设施所覆盖的水域被列为支持鱼类和野生动物繁殖、主要和 二次接触娱乐以及生活、农业和工业供水用途。2014年至2019年进行了水质监测，以确保这些设施不会对项目河段的溶解氧和水温产生不利影响。
最初建造的船闸和水坝设施包括 鱼道 梯子或 鱼道。然而，目前这些设施仅剩残骸。项目区域的高流量和洪水必将破坏在项目区提供永久鱼类通道的任何尝试。阿肯色州鱼类和野生动物委员会和项目业主已经联系，讨论季节性鱼类通道结构的可能性，但尚未提供正式的建议或方案。常驻鱼类包括虹鳟和割喉鳟（每年在布尔肖尔斯湖放养）、克拉皮鱼、黑鲈鱼、白鲈鱼、鲶鱼、溪鳟鱼、西鲱和大眼鲷。鳟鱼并非阿肯色州本土物种，但据指出，这些渔业是由于美国陆军工程兵团在怀特河沿岸的水坝排放冷水造成的。
The project lands consist of roughly 42 acres. The property surrounding LD3 are primarily undeveloped forested and agricultural lands. An Erosion and Sedimentation Control Plan, Wildlife/Vegetation Management Plan and 湿地/洪泛区 管理计划和猛禽保护计划均已在项目实施。美国鱼类及野生动物管理局 (USFWS) 和 AGFC 已审查这些计划，但未提出任何意见。
项目区域内可能存在的受威胁和濒危物种包括北长耳蝠、印第安纳蝙蝠、灰蝙蝠、东部黑秧鸡、环颈鸻、红腹滨鹬、欧扎克大鲵、密苏里囊豆和奔牛三叶草。项目区域内不存在这些物种的关键栖息地，项目运营不会对它们造成影响。
这些船闸和水坝被确定有资格列入 国家历史遗迹名录 and construction of the hydroelectric stations would require removal of portions of the existing lock and dam structures. At that time, the Arkansas State Historic Preservation Officer (SHPO) noted this would constitute an adverse impact on the eligible properties and recommended documentation of the projects prior to demolition. LD3 required coordination with the Arkansas SHPO to record all or part of the Lock and Dam No. 3, construct a scale map to show the relation of the lock and dam to other historic complexes on the White River. The project owner complied and produced such materials for the historical record.
Recreational resources at the project are limited due to lack of access points to the river. Some boating occurs upstream and downstream of the project. Public access is provided free of charge where safe.
