The Southern Whitewater River Watershed is located in southeastern Indiana along the Ohio state border and drains portions of Rush, Decatur, Union, Franklin, Dearborn and Ripley Counties. The watershed has a surface area of 412 square miles and drains a total of 1,370 square miles. Major waterbodies included in the Total Maximum Daily Load (TMDL) report are Whitewater River, Salt Creek, Bull Fork, Little Salt Creek, Pipe Creek, Clear Creek, Duck Creek, Blue Creek, Yellow Bank Creek, Gobles Creek, Logan Creek, Johnson Fork and Big Cedar Creek.
A preliminary survey of the Southern Whitewater River Watershed was conducted by Indiana Department of Environmental Management (IDEM) in 2007 through the probabilistic sampling program. Impairments include dissolved oxygen, E. coli, and PCB and total mercury in fish tissue. Potential pollution sources in the watershed include nonpoint sources from forested lands and pastures, land application of manure and urban and rural run-off, as well as point sources from straight pipe discharges, and home sewage treatment system disposal.
IDEM will complete a comprehensive sampling program in the watershed that will be based on the current impairments. Approximately 33 sites will be assessed for general chemistry, nutrients, habitat, fish and macroinvertebrate communities, and stream flow. For a comprehensive list of all parameters please reference the approved work plan.
Two TMDL public kickoff meetings will be held on October 29, 2013. The first meeting will be held at 2:00 PM (EDT) at the Franklin County Government Center, 1010 Franklin Avenue, Brookville, IN 47012. The second kickoff meeting will be held at 6:00 PM (EDT) at the Batesville Middle School, 201 North Mulberry Street, Batesville, IN 47006. Meetings will cover the same topics.
Additional meetings will be held as needed. Please check the IDEM calendar for updates.
A draft TMDL meeting will be held in Summer 2015 once the comprehensive sampling program is complete.
