Lindsay Creek & Hatwai Creek Watershed Advisory Group

Watershed Advisory Groups (WAGs) are groups of citizens that provide DEQ with local public input and guidance regarding specific watersheds. WAGs advise DEQ on development of water quality improvement plans called Total Maximum Daily Loads (TMDLs), and provide guidance on how to implement water quality improvements in these watersheds. WAGs also advise DEQ during periodic checkups on TMDLs. Idaho Code §39-3611(7) requires DEQ to review approved TMDLs every five years to evaluate if assumptions, analyses, targets, and loads developed in TMDLs are still appropriate, or changes are needed.

This WAG was formed to advise DEQ on water quality management in Lindsay Creek, Hatwai Creek, and Tammany Creek. The WAG advised DEQ on development of water quality improvement plans called TMDLs, and provided guidance on how to implement water quality improvements in these watersheds.  In 2018-2019, DEQ is reviewing the Lindsay Creek and Hatwai Creek TMDLs. This page provides information for the WAG and general public relevant to the TMDL review process.
