Geography. The Fourmile Creek
watershed occupies south-central Clark County. The land is in the Bluegrass
physiographic region, characterized by hilly or undulating terrain, medium to
very rapid rates of surface runoff, and slow to medium groundwater drainage.
Much of the watershed lies 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 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). Still other
areas are underlain by interbedded limestones and shales (>20% limestone,
allowing groundwater flow where the clay content is low enough).
Waterways. Fourmile Creek empties into the Kentucky River east of
Ford. Among the creeks that feed it are Stoner Branch, Harris Branch, and East
Fork Fourmile Creek.
Land and water use. Land in the watershed is 85% agricultural, more
than 10% rural and wooded, and almost 3% residential. No businesses or
organizations hold permits for discharges into the creeks. See tables for
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. No volunteer data were collected in this watershed in
