Lower Boise River 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 Lower Boise River WAG was formed to develop and implement TMDLs to improve water quality in the Lower Boise River. DEQ will consult with WAG participants on a regular basis throughout the TMDL development and/or five-year review process.
