OVERVIEW

Geography. The Drowning Creek watershed lies along the boundary between Madison and Estill Counties. The land is in the Knobs physiographic region, characterized by hilly terrain, very rapid surface runoff, and very slow groundwater drainage. In level parts of the Knobs, runoff and groundwater drainage are slow. The watershed lies partly above fractured shales through which groundwater can easily move but which stores very little water. Other sections of the watershed lie over easily weathered clay shales that store water but allow little groundwater flow. The rest of the watershed lies over interbedded shales and limestones (these are 20% limestone; water conduction is poor because of the clay content of the shale).

Waterways. Drowning Creek empties into the Kentucky River northeast of Bybee. Among the creeks that feed it are Knob Lick Branch, Oldham Branch, Butler Branch, and Black Branch.

Land and water use. Land in the watershed is about 55% agricultural and more than 40% rural and wooded. Two businesses and organizations hold permits for discharges into the creeks. See tables for details.

Agency data assessment. The assessed creek segments in this watershed fully support their designated uses, based on biological and/or water-quality data. 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. There is a volunteer sampling site on Drowning Creek. See tables for details.
