Water quality data collection (Turbidity, Dissolved Oxygen, Specific Conductance, pH, Nitrate, and Water Temperature) will be discontinued on March 1, 2026, due to loss of project staff. Due to the Federal Hiring freeze we are incapable of replacing staff at this time. If you have any questions or concerns, please contact the Central Midwest Water Science Center, Heather Krempa (hkrempa@usgs.gov).
