Portneuf River & Tributaries Watershed Advisory Group (WAG)
Watershed advisory groups (WAGs) are groups of interested citizens that provide local public input and guidance to DEQ during the development of water quality improvement plans or "Total Maximum Daily Loads" (TMDLs) for water bodies that fail to meet water quality standards. TMDLs are designed to reduce the levels of pollutants, such as bacteria and sediment, in impaired water bodies.
The Portneuf River & Tributaries WAG was formed to develop and implement TMDLs to improve water quality in the Portneuf River Subbasin. A water body assessment and TMDL document was developed in 1999, followed by a supplement and implementation plan in 2001 and 2003. The WAG met from November 2006 to December 2008 to develop a revision and addendum, which was submitted to and subsequently approved by EPA in August 2010.
