Land use in the Snake River - St. Croix Basin ranges from largely agricultural and urban in the south to largely forest and wetland in the north.
What's being done
Monitoring and assessment
Monitoring work for the watershed study began in 2010.
Ann River TMDL Project: Stressor identification report (wq-iw6-07m)- Mud Creek (Snake River Watershed) Stressor Identification Report (wq-iw6-11n)
- Snake River Watershed Monitoring and Assessment Report (wq-ws3-07030004)
The Snake River Watershed was sampled for stream biology in 2007, and served as a pilot for what would become the MPCA's "Watershed Approach" to monitoring and assessment in future years. Since then, stream chemistry and lake monitoring have been incorporated into the Watershed Approach. In addition, the assessment methods have changed since 2007. The assessments for the Snake River Watershed have been revised according to the new methods, but the report above was not rewritten to reflect these changes. As such, the assessment decisions in the report may differ from those recorded in the MPCA's databases. The Snake River Watershed is being resampled in 2017 and 2018. We anticipate these data will be assessed in 2019.

Implementation plans
There is currently one sub-watershed TMDL complete (Groundhouse River), and one currently underway (Ann River subwatershed for biota, bacteria, and excess nutrients).
