USACE CWMS - Kentucky River Watershed

The Corps Water Management System (CWMS) includes four interrelated models to assist with water management for the basin:

- GeoHMS (Geospatial Hydrologic Modeling Extension)
- ResSIM (Reservoir System Simulation)
- RAS (River Analysis System)
- FIA (Flood Impact Analysis)

The Kentucky River is formed in eastern Kentucky at Beattyville, in Lee County, by the confluence of the North, Middle and South Forks at about 670 feet (200 m) elevation, and flows generally northwest, in a highly meandering course through the mountains, through the Daniel Boone National Forest, then past Irvine and Boonesborough, then southwest, passing south of Lexington, then north through Frankfort. It joins the Ohio at Carrollton.

The North Fork Kentucky River is approximately 168 miles (270 km) long. It rises on the western side of Pine Mountain, in the Appalachians of extreme southeastern Kentucky, in eastern Letcher County near the Virginia state line in Payne Gap, near the intersection of US 23 and US 119. It flows generally northwest, in a winding course through the mountainous Cumberland Plateau, past Whitesburg, Hazard and Jackson. It receives Rockhouse Creek at Blackey near its source. Approximately 8 miles (13 km) southeast of Hazard, it receives the Carr Fork. It receives Troublesome Creek at Haddix, southeast of Jackson. Three miles upstream from its confluence with the South Fork, it receives the Middle Fork. It joins the South Fork to form the Kentucky at Beattyville.

The Middle Fork Kentucky River is a tributary of the North Fork Kentucky River, approximately 105 miles (169 km) long, in southeastern Kentucky. It rises in the Appalachian Mountains in southernmost Leslie County, approximately 16 miles (26 km) from the Virginia state line, and flows north through the Cumberland Plateau past Hyden. At Buckhorn, it is impounded to form the Buckhorn Lake reservoir. North of the reservoir it flows generally northwest and joins the North Fork in Lee County, approximately 5 miles (8 km) east of the confluence of the North and South forks at Beattyville.

The South Fork Kentucky River is approximately 45 miles (72 km) long. It is formed in Clay County, at the town of Oneida in the Daniel Boone National Forest, approximately 10 miles (16 km) northeast of Manchester, by the confluence of Goose Creek and the Red Bird River. It flows generally north in a highly meandering course through the mountainous Cumberland Plateau region. It joins the North Fork to form the Kentucky at Beattyville.

美国陆军工程兵团水资源管理系统（Corps Water Management System, CWMS）包含四个相互关联的模型，用于辅助流域水资源管理：
- 地理空间水文建模扩展模块（Geospatial Hydrologic Modeling Extension, GeoHMS）
- 水库系统模拟模块（Reservoir System Simulation, ResSIM）
- 河流分析系统（River Analysis System, RAS）
- 洪水影响分析模块（Flood Impact Analysis, FIA）

肯塔基河形成于肯塔基州东部比蒂维尔（李县），海拔约670英尺（200米）处，由北、中、南三条支流汇流而成。河道整体大致向西北方向蜿蜒穿行于山区，流经丹尼尔·布恩国家森林，随后途经欧文和布恩斯伯勒，继而转向西南，从列克星敦南侧经过，再向北流经法兰克福，最终在卡罗尔顿汇入俄亥俄河。

北支肯塔基河全长约168英里（270公里），发源于肯塔基州极东南部阿巴拉契亚山脉的松山西侧，地处莱特彻县东部靠近弗吉尼亚州界的佩恩加普，临近美国23号与119号公路交汇处。河道整体大致向西北方向蜿蜒流经多山的坎伯兰高原，途经怀特斯堡、哈泽德和杰克逊。其在源头附近的布莱基处接纳罗克豪斯溪（Rockhouse Creek）；在哈泽德东南约8英里（13公里）处，它接收卡尔弗特支流；在杰克逊东南的哈迪克斯处，它接纳塔布尔瑟姆溪（Troublesome Creek）。在与南支汇流上游3英里处，它汇入中支肯塔基河，最终与南支在比蒂维尔汇流，共同形成肯塔基河。

中支肯塔基河是北支肯塔基河的支流，全长约105英里（169公里），位于肯塔基州东南部。其源头位于阿巴拉契亚山脉的莱斯利县最南端，距离弗吉尼亚州界约16英里（26公里）处，向北流经坎伯兰高原，途经海登。在巴克霍恩处，河道被筑坝拦截形成巴克霍恩湖水库。水库以北河段整体大致向西北方向流，在比蒂维尔北、南支汇流点以东约5英里（8公里）处的李县，与北支汇流。

南支肯塔基河全长约45英里（72公里），形成于克莱县丹尼尔·布恩国家森林内的奥尼达镇，地处曼彻斯特东北约10英里（16公里）处，由古斯溪（Goose Creek）与红鸟河（Red Bird River）汇流而成。河道整体大致向北，在多山的坎伯兰高原地区蜿蜒穿行，最终与北支在比蒂维尔汇流，共同形成肯塔基河。
