OVERVIEW
Geography. The Tenmile Creek
watershed occupies northwestern Grant County and adjacent corners of Gallatin,
Boone, and Kenton Counties. The land is in the hills of the bluegrass subregion
of the Bluegrass physiographic region, characterized by hilly terrain, very
rapid surface runoff, and slow groundwater drainage. The watershed lies partly
above thick layers of easily dissolved limestone that form carbonate aquifers.
Groundwater flows through channels in the limestone, so caves and springs are
common in regions with this geology. Other areas lie above interbedded
limestones and shales (>20% limestone, allowing groundwater flow where the
clay content is low enough).
Waterways. Tenmile Creek empties into Eagle Creek near Folsom. Among
the creeks that feed it are Kittle Run, Bullock Run, Sulphur Lick Branch, North
Fork, Little Tenmile Creek, Arnolds Creek, Flat Creek, and Napolean Branch.
Land and water use. Land in the watershed is about 60% agricultural,
30% rural and wooded, and 10% residential or commercial. The surface waters of
the watershed supply the drinking water for the Bullock Pen Water District. Five
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 one (Arnolds Creek) that only partially supports its designated uses,
based on biological and/or water-quality data. Siltation contributes 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.
