Water Quality Plans & Reports in DEQ's Twin Falls Region

This region boasts a myriad of water resources: renown hot springs; lakes, reservoirs, and rivers that attract anglers, boaters, and swimmers; and the Lower Portneuf River Valley Aquifer that supplies drinking water to tens of thousands of Idahoans.  Economic activities in this portion of the state include phosphate mining and processing and agricultural production of wheat, potatoes, and sugar beets. These activities have the potential to impact the region's water quality.
