The Brush Creek
watershed covers northeastern Owen County and an edge of Grant County. 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. 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).
Waterways. Brush Creek empties into Eagle Creek just over the Owen
County line in Grant County, north of Jonesville. Among the creeks that feed it
are Sand Lick Branch, Rudder Branch, Slab Lick Branch, Long Branch, and Buffalo
Branch.
Land and water use. Land in the watershed is more than 75%
agricultural and about 25% rural and wooded. No businesses or organizations hold
permits for discharges into the creeks. See tables for details.
Agency data assessment. The assessed creek segment in this watershed
fully supports all its 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
1999.
