2 Geography. The watershed covers southwestern Carroll County and north-central Henry County, with a sliver of Trimble County. The higher, Henry County portion of the watershed is in the outer subregion of the Bluegrass physiographic region, characterized by undulating terrain, moderate to rapid surface runoff, and moderate rates of groundwater drainage. The lower, Carroll County portion of the watershed is in the hills of the bluegrass subregion, characterized by hilly terrain, very rapid surface runoff, and slow groundwater drainage. Parts of the watershed lie over interbedded shales and limestones (these are % limestone; water conduction is poor because of the clay content of the shale). Other areas are underlain by interbedded limestones and shales (>% limestone, allowing groundwater flow where the clay content is low enough). Waterways. empties into the Kentucky River east of English. Among the creeks that feed it are Long Branch, East Fork, West Fork, Gilgal Branch, Pryor Branch, and Lees Creek. Land and water use. Land in the watershed is about 5% residential and commercial; the rest of the watershed is roughly equally divided between agricultural and rural and wooded land. No businesses or organizations hold permits for discharges into the creeks. See tables for details. Agency data assessment. The assessed creek segments in this watershed include one (West Fork) that only partially supports its designated uses, based on biological and/or water-quality data. Siltation and stream modification contribute to the impairment of the stream. See tables for details. Watershed rankings. The ranking formula provides a preliminary ranking by synthesizing a broad spectrum of watershed characteristics, current conditions, and threats. This watershed ranks in the group with the lowest need for protection and/or restoration. This rating is for the watershed on average: particular sites and particular waters within the watershed may vary widely. See tables for details. Volunteer data. No volunteer data were collected in this watershed in 1999.
