OVERVIEW
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.
