Baseflow measurements of field parameters

Detailed Description

The team of USGS scientists collected stream water samples before and after rainfall events for this study. In this photo a USGS scientist is taking measurements of field parameters (dissolved oxygen, water temperature, specific conductance, and pH) from New York Branch, Iowa, at low flow (baseflow) conditions.
