| Study Name | Weaver Creek (Mason County) Fecal Coliform TMDL Attainment Monitoring |
| EIM Data Entry Review Status | Reviewed |
| Study Type | Total Maximum Daily Load (TMDL) effectiveness monitoring |
| Study Purpose | Ecology’s 2007 water quality attainment monitoring report on the Skokomish River Basin concluded that all sites assessed, with the exception of Weaver Creek, met the 2001 TMDL target limits for fecal coliform (Sargeant et al., 2007, Seider et al., 2001). Although Weaver Creek met the Extraordinary Primary Contact classification water quality standard (50 cfu/100ml) for recreation, an additional 20% reduction in fecal coliform levels is needed to meet the TMDL target value. Since 2007, more restoration work has been done on Weaver Creek. It is believed that sufficient progress has been made to meet TMDL target limits for fecal coliform.
This addendum uses methods, sampling designs and quality control procedures outlined in the original attainment monitoring QAPP (Batts D., 2005) to develop a monitoring strategy for Weaver Creek. This sampling strategy will provide sufficient data to determine if Weaver Creek is currently meeting the original TMDL target values for fecal coliform. |
