Ohio River Tributary Watersheds: South

Ohio River Tributaries SouthThe Ohio River tributaries (south) watershed is located in southern Ohio. It drains a total of 640 square miles and flows through all or part of five counties. Major municipalities partially or fully in the watershed include Portsmouth and Cincinnati.

The eastern portion of the watershed is predominantly comprised of forest with some areas of cultivated crops pasture and hay lands. The central portion of the watershed is a mixture of cultivated crops, pasture and hay lands and forest. The western portion of the watershed is primarily comprised of urban development.

Ohio Brush Creek Watershed

Ohio Brush Creek watershedOhio Brush Creek is located in southern Ohio. Ohio Brush Creek flows into the Ohio River in Adams County. The Ohio Brush Creek watershed is located in Adams, Brown, Highland, Pike and Ross Counties. Land use is dominated by forest and pasture/row crop. Villages within the watershed include Winchester, Seaman, Peebles and West Union.













Monitoring

The entire watershed was studied during 2007.  The Ohio Brush Creek watershed is divided into three subwatersheds, as follows:

  • 05090201 03        Headwaters Ohio Brush Creek
  • 05090201 04        West Fork Ohio Brush Creek
  • 05090201 05        Lick Fork-Ohio Brush Creek

Pine Creek, Ice Creek and Little Scioto River Watersheds

Pine and Ice Creeks and Little Scioto River watershedsThe Little Scioto River and Pine and Ice Creeks are the largest tributaries in the study area and they flow into the Ohio River near Portsmouth in Scioto County. The majority of the TMDL area is in Scioto and Lawrence Counties, with smaller proportions in Jackson and Pike Counties. 65 percent of the area is forested while pasture and cropland accounts for 14 and 6 percent of the area respectively. Open space to high intensity development account for 9 percent while the remaining 9 percent of the land area is distributed across other land classifications.









Monitoring

Several tributaries to the Ohio River in southeast Ohio were studied during 2010.  The project area is divided into four subwatersheds, as follows:

  • 05090103 01        Ice Creek – Ohio River
  • 05090103 02        Pine Creek
  • 05090103 05        Headwaters Little Scioto River
  • 05090103 06        Little Scioto River – Ohio River

White Oak Creek

White Oak Creek watershedThe White Oak Creek watershed drains 234 square miles of southwest Ohio. White Oak Creek drains directly into the Ohio River and covers portions of Highland and Brown counties. Larger municipalities include Mount Orab, Georgetown, Mowrystown and Sardinia.













Monitoring

Ohio EPA conducted a comprehensive physical, chemical and biological survey of the White Oak Creek watershed in 2006, and several problems were identified.  The survey results were published in December 2008 (see below).  Major causes of impairment are nutrients, sedimentation/ siltation, degraded habitats, bacteria and atrazine.  Major sources of impairment include nonpoint source pollution and habitat degradation associated with farming practices and drainage improvements; urban land uses; and failing home sewage treatment systems.

TMDL Report

The White Oak Creek Total Maximum Daily Load (TMDL) report was approved by U.S. EPA on February 25, 2010.  TMDL reports identify and evaluate water quality problems in impaired water bodies and propose solutions to bring those waters into attainment with water quality standards.

TMDLs were prepared for fecal coliform, nitrate+nitrite, total suspended solids, total phosphorus, ammonia, and atrazine.  This was Ohio’s first TMDL for a public drinking water supply.

Potential solutions include:

  • habitat improvement and stream restoration
  • reduction of nutrients through agricultural best management practices
  • reduction of bacteria through repairing or replacing failing home sewage treatment systems and reducing manure applications
  • reduction of atrazine through wider stream buffers and better education of product label instructions

Southwest Ohio River Tributaries

Other Ohio River tributaries

This area includes multiple tributaries to the Ohio River along the southern border of Ohio west of the Scioto River. Major tributaries include Salt Lick Creek, Cabin Creek, Eagle Creek, Straight Creek, Bullskin Creek, Twelvemile Creek and Muddy Creek. In the eastern tributaries, forest predominates the land use. Land use in the central tributaries is a mixture of forest, pasture and hay lands and cultivated crops. In the western tributaries, urban development becomes much more prevalent.









Monitoring

This watershed was studied in 2014 and 2016.  

The 2014 watershed survey included Upper Mill Creek, Rapid Run, Muddy Creek, Bullskin Creek, Crooked Run, Bear Creek, Maple Creek, Little Indian Creek, Big Indian Creek, Boat Run, Twelvemile Creek, Tenmile Creek, Ninemile Creek, Eightmile Creek and Fivemile Creek.

The 2016 watershed survey included Turkey, Straight and Eagle Creeks.
