WAG Documents: Meeting Materials and Agendas, Review Documents, and Resources

The Middle Snake River WAG was originally created in 1995 as an outgrowth of the House Bill 1284 (WAG-BAG Law). The primary purpose and concern was to provide input to DEQ and EPA in restoring the beneficial uses and water quality standards of the Snake River, Rock Creek and their major tributaries. The Middle Snake River WAG encompasses one major subbasin, the Upper Snake Rock Subbasin. From this group, and in cooperation with DEQ, have come the Middle Snake River Watershed Management Plan (approved 1997), the Upper Snake Rock Watershed Management Plan (2000) and the Upper Snake Rock TMDL Modification (2005). The WAG has stakeholder industries that represent irrigation agriculture, confined animal feeding operations, food processors, aquaculture, municipalities, grazing, recreation, and forestry. Ground water is also a concern to the WAG and is also included in the approved TMDLs.

Currently, the WAG meets quarterly (or as needed) and continues to provide input to DEQ and EPA on TMDL issues and other water quality related issues. Content on this page is provided for informational purposes while the Middle Snake WAG and DEQ work to conduct a 5-year review of the Middle Snake River Subbasin Assessment, TMDL, and Implementation Plan.
