Geography. The Drennon Creek watershed occupies central Henry County. The higher, southern 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, northern 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 20% limestone; water conduction is poor because of the clay content of the shale). Other areas are underlain by interbedded limestones and shales (>20% limestone, allowing groundwater flow where the clay content is low enough). Unconsolidated silts, sands, and gravels occur along the flood plain of the creek.

Waterways. Drennon Creek empties into the Kentucky River east of Drennon Springs. Among the creeks that feed it are Town Creek, Rush Creek, Fivemile Creek, Flag Run, Emily Run, Martini Run, Holy Water Branch, Greens Fork, Boling Branch, and Sulphur Creek.

Land and water use. Land in the watershed is 75% agricultural, 20% rural and wooded, and less than 5% residential and commercial. Four businesses and organizations hold permits for discharges into the creeks. See tables for details.

Agency data assessment. The assessed creek segments in this watershed include two that do not support some or all of their designated uses, based on biological and/or water-quality data. Two are classified as threatened. Siltation, organic enrichment, habitat alteration, and municipal point sources contribute to the impairment of these streams. 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.
