White River Lock and Dam No. 1 (LIHI #179), Lock and Dam No. 2, and the 「Shelby M. Knight」 3 號船閘與大壩 (LIHI #181) (e.g., LD1, LD2, LD3) Hydroelectric Projects are 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. LD2 is located in Independence County, AR at river mile 308.3 between LD1 and LD3.
LD2 includes a concrete and 木製嬰兒床 壩 approximately 658 feet long and 29 feet high with an integral navigation lock approximately 175 feet long and 36 feet wide on the right side of the dam. A multi-level intake 水槽, approximately 120 feet long and 100 feet wide is located within the lock structure.
The dam creates an impoundment with a surface area of approximately 1,072 acres at maximum pool elevation. The 發電站 contains a single vertical Kaplan turbine and generating unit with a capacity of 3.9 MW and a design flow of 3,180 cfs. The average annual generation is approximately 15,400 MWh. An open flume tailrace, approximately 120 feet long conveys water back to the river. The Project boundary encompasses the high-water mark and about 10 acres of land around Project structures.
The Project is operated in an instantaneous 徑流 模式。 LD1、LD2 和 LD3 的流入量取決於懷特河布爾肖爾斯上游美國陸軍工程兵團水壩和北福克河諾福克湖以及其他支流的流出量。沒有 溢洪道 蓋茲 在任何一座水壩。與河流流量相比，工廠流量較低，蓄水水位很少下降到或低於 溢洪道. 徑流 根據阿肯色州貝茨維爾白河沿岸的美國地質調查局測量儀來監測運作和流量。
這三個設施所及水域被列為支持魚類和野生動物繁殖、主要和 二次接觸娛樂以及生活、農業和工業供水用途。 2014年至2019年進行了水質監測，以確保設施不會對工程河段的溶氧和水溫產生不利影響。
最初建造的船閘和水壩設施包括 魚道 梯子或 魚道. However, only remnants of these facilities currently remain. High flows and flooding in the project area would certainly destroy any attempt to provide permanent fish passage at the projects. Arkansas Fish and Game Commission and the project owner have been in contact to discuss the potential for seasonal fish passage structures though no formal recommendations or prescriptions have been provided. Resident fish species include rainbow and cutthroat trout, (stocked annually in the Bull Shoals Lake) crappie, black bass, white bass, catfish, brook trout, shad, and walleye. Trout are not native to Arkansas, but the fisheries have been noted to be a result of the cold water discharge from the USACE dams along the White River.
The project lands consist of roughly 10 acres. The property surrounding LD2 is primarily undeveloped forested and agricultural lands. An Erosion and Sedimentation Control Plan, Wildlife/Vegetation Management Plan and 濕地/洪氾區 管理計劃和猛禽保護計劃均已在專案中實施。美國魚類與野生動物管理局（USFWS）和 AGFC 審查了該計劃，但未發表任何意見。
Threatened and endangered species potentially present in the project area includes Northern long-eared bat, Indiana bat, gray bat, Eastern black rail, piping plover, red knot, Ozark hellbender, Missouri bladderpod, and running buffalo clover. No critical habitats for these species are present in the project area and project operations do not impact them.
這些船閘和水壩被確定為有資格列入 國家歷史遺跡名錄 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. LD2 required coordination with the Arkansas SHPO to record all or part of the Lock and Dam No. 2, 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 include boating access, informal camping areas, and fishing access downstream of the dam. The powerhouse and lock are fenced in for safety. Public access is provided free of charge where safety and private property do not preclude access.
