Goose Creek Watershed
Fecal Coliform TMDL 

The Goose Creek watershed is located in Mecklenburg County and Union County, North Carolina. The headwaters of the watershed originate in Mecklenburg County and flow through the Town of Mint Hill into Union County, North Carolina and into the Rocky River.

Stevens and Duck Creeks, which originate in Mecklenburg County, are both tributaries to Goose Creek. Stevens Creek flows into Goose Creek at the Mecklenburg-Union County line west of Stevens Mill Road while Duck Creek joins Goose Creek just upstream of Brief Road.  

North Carolina's 2002 Integrated Report, which includes 305(b) reports and 303(d) lists of impaired waters, was approved by EPA Region IV on March 18th, 2003. The 2002 list identified the 17.0 mile segment of Goose Creek from its source to the Rocky River as impaired due to elevated fecal coliform concentrations. The objective of this study was to develop a fecal coliform TMDL using a watershed approach for Goose Creek. This TMDL encompasses all the stream segments listed in the 2002 303(d) list for this watershed.  The NC DWQ Water Quality Standard for fecal coliforms is as follows:

Fecal coliforms shall not exceed a geometric mean of 200/100mL (membrane filter count) based upon at least five consecutive samples examined during any 30-day period, nor exceed 400/100 ml in more than 20 percent of the samples examined during such period.

In response to the high level of interest in this TMDL from local government officials and concerned citizens, a stakeholder group was formed in 2003. The stakeholder group, led by the Charlotte-Mecklenburg Storm Water Services' County Water Quality Program and the NC Division of Water Quality (DWQ), took an active role in the TMDL development process.  County Water Quality staff was able to take the lead role in both the source assessment and model development.

The TMDL was developed and approved on July 8, 2005 and source allocation is as follows:

Implementation

In August of 2006 the Towns of Mint Hill, Stallings and Indian Trail received letters from the State of North Carolina ordering them to develop a Water Quality Recovery Program for the Goose Creek Watershed.  The Towns, in conjunction with Mecklenburg and Union Counties, have elected to work together to develop the program.  The Water Quality Monitoring portion of the plan has been developed and is currently in review.
