The Logan Creek
watershed lies in central Lincoln County. The land 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 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. There are also areas of interbedded shales and limestones
(these are 20% limestone; water conduction is poor because of the clay content
of the shale) and areas of interbedded limestones and shales (>20% limestone,
allowing groundwater flow where the clay content is low enough). Interbedded
clay shales and siltstones underlie the rest of the area.
Waterways. Logan Creek empties into the Dix River northeast of
Stanford, near Logantown. Among the creeks that feed it are Saint Asaph Creek
and Neals Creek.
Land and water use. Land in the watershed is about 70% agricultural,
20% rural and wooded, and 10% residential or commercial. The surface waters of
the watershed supply the drinking water for the municipal system in Stanford.
Two businesses and organizations hold permits for discharges into the creeks.
See tables for details.
Agency data assessment. The assessed waters in this watershed include
Stanford Lake, which only partially supports its use as a drinking water supply,
based on biological and/or water-quality data. Excess nutrient enrichment
contributes to impairment of the lake. 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. See tables for details.
